2.0 General Overview
This manual will cover both the Push orp 0605 and 1503 Series Servo Motors as
they share many common components. The 0605 and 1503 (motor) are capable of
continuously producing 5 and 3 horsepower, and spinning up to 6000 rpm and 15000
rpm respectively. The motors come in two models; a model SM0605 or SM1503
utilizing a manual collet, and a ST 0605-BT30 or ST 1503-BT30 automatic version
which allows changing out tools via a BT30 toolholder. These versions utilize
identical motor windings, and power amplifiers. Differing only in a few physical
dimensions and how they secure the media. Each of these motors provide a
convenient and effective means to spin and/or change any number of different media
types to support a fully automated workcell.
The Servo Manual (SM) models have a manually tightened collet that is a cost-
effective alternative to the automatic version. The “SM” models use the same motor
winding and housing as the automatic “ST ”, but without the automatic clamping
mechanism. The manual ollet is a standard ER-20 series collet designed to clamp a
½ inch (12.7 mm) diameter Toolholder. The user may choose different sized collets
in the ER-20 series, ranging from .031-.500 inch (1mm – 13mm).
The Servo Tool hanger (ST ) automatic tool-changing models, actuate
pneumatically to secure the BT30 style toolholder. They are comprised of four
primary components: a high-torque Servo Motor, a pneumatic actuator, high force
Belleville springs, and a component to clamp a Toolholder. The ST version uses a
drawbar to pull the ollet/Gripper in. High force Belleville springs located at the back
of the Servo Motor tension the drawbar. Actuating the large pneumatic actuator,
located in the lamping Housing, opens the ollet/Gripper. During pressurization the
cylinder contacts the Belleville springs and compresses them to drive the
ollet/Gripper out, releasing the Toolholder. There is no mechanism to forcibly eject
the Toolholder from the ollet, so gravity or a capturing mechanism must be used.
The ST models use a 30 taper to grip a standard BT30 toolholder. This design
locks the toolholder in the 30 tapered shaft and resists large pull out forces. The shaft
does not have locking keys, so motor indexing for tool change is not required. The
ST motors are fail-safe, in that no air pressure is required to hold the Toolholder.
Therefore, the Toolholder will remain held in the ollet/Gripper even when the air
pressure is un-expectantly lost. Likewise, applying air pressure to a single input port
via a simple manual or electrically operated valve opens the ollet/Gripper and
releases the Toolholder. The clever mechanical design always isolates the motor
bearings from the drawbar tension. This greatly improves reliability by allowing the
motor shaft to spin freely and never be subject to any clamping forces. All Push orp
motors use sealed bearings to ensure a long life. The bearings have additional
contamination protection from a Push orp proprietary contact shaft seal. This special
seal eliminates the need for constant purge air.
During operation the motor generates considerable heat due to the high torque and
compact size of the motor. Excessive operating temperatures will significantly reduce
the life of the motor. Water ooling is required to keep the unit within the internal
temperature operating range. The motor should never be allowed to exceed a
temperature of 176 F (80 ). ontinuously operating the unit above 176 F (80 )
will cause the rotor to de-magnetize and the bearings to fail. High temperatures will

PUSHCORP, INC. 0605 / 1503 Servo Motor Series Manual 4
also cause the O-rings that seal the cooling water channels to fail, possibly filling the
motor with water. Push orp has provided flow through water cooling on the motor to
allow high duty cycles without overheating.
Simple reliable construction combined with high torque and precision speed controlled
servo technology make the PushCorp Servo Motor line a rugged, state-of-the-art tool
capable of providing flexible, cost-effective operations.
3.0 Installation & Operation
3.1 Mounting t e spindle motor
3.1.1 Mounting to a Pus Corp AFD compliant tool
The motors are designed to attach directly to the arriage of any PushCorp
AFD1000/70 Force Device. There are two standard attachment options. The SM
version uses a Mounting Plate, and the ST motor uses the lamping Housing for
attachment.
The Parallel-Axis configuration is shown in Figure 1, where the motor attaches to the
AFD arriage with a Parallel Bracket. The Parallel Bracket is positioned on the
arriage and attached using the four (4) supplied M6x1x20mm Socket Head ap
Screws. The motor is then attached to the Parallel Bracket, as shown, with two (2)
M6x1x20mm Socket Head ap Screws into the front of the Motor Housing. Two (2)
M6x1 Socket Head ap Screws pass through the lamping Housing/Mounting Plate
(length is dependent on motor SMxxxx = 25mm, ST xxxx-BT30 = 145mm). The
fasteners must be tightened to the torque specified in Section 4.0.
To attach the motor to an AFD in a Perpendicular-Axis configuration, position the
lamping Housing/Mounting Plate over the arriage as shown in Figure 2. Then
secure the unit using four (4), M6x1 Socket Head ap Screws (length is dependent
on motor SMxxxx = 25mm, ST xxxx-BT30 = 145mm). Tighten the fasteners to the
torque specified in Section 4.0. 5mm Dowel pins can be inserted and glued into the
arriage to align the motor. The lamping Housings and Mounting Plate have pre-
drilled clearance dowel holes for this configuration.
CAUTION: Make sure t at t e M6x1 fasteners do not exceed a dept of 0.40”
(10 mm) into t e AFD Carriage Helicoils or damage will occur.
CAUTION: Do not press Dowel Pins into t e AFD Carriage, t is will damage
t e linear rails.

3.1.2 Mounting Directly to a Robot
For some processes compliance and force control are not required. The motor can
be mounted directly to the robot. This robotic system is equivalent to a 5-axis
machining center with a very large work volume and lower positional accuracy.
ertain product types and processes are well suited for a Robotic Machining enter
(RM ).
The motor can be attached to the robot mounting flange using a customer supplied
mounting plate. For direct mounting it is recommended that a breakaway clutch is
installed. The breakaway clutch will help protect the motor in the event of a robot
crash. Loads on the motor shaft of over 300 lb (136 kg) radially and 150 (68 kg)
axially will damage the bearings.
To mount the motor, first attach the customer supplied Mounting Plate to the Robot
Mounting Flange or to the Breakaway lutch, per the manufacturer’s specifications.
Once the Mounting Plate is secured, place the motor against the Mounting Plate and
install (4) four, M6x1, Socket Head ap Screws (length is dependent on motor
SMxxxx = 25mm, ST xxxx-BT30 = 145mm). (See Figure 3) Tighten the fasteners to
the torque specified in Section 4.0.
3.2 Media and Tool Presentation
Media and tool presentation refers to how various disks, drill bits, router bits, etc. are
presented so that a robot may maneuver the motor into position to grasp the
Toolholder reliably. It is ultimately the user’s responsibility to provide a means to
present the media and/or tooling in an effective and repeatable way for a given
application.
Figure 3: Spindle Motor Direct Mounting

PUSHCORP, INC. 0605 / 1503 Servo Motor Series Manual 7
As shown above, in Figure 4, many types of media and tools may be accurately
located in a Tool radle. A robot can then be taught approach paths and docking
locations to reliably bring the motor down over the Toolholders and grasp them. The
motor’s ollapsing ollet allows 0.015 in. (0.38 mm) diametrical clearance around the
Toolholder when open. The Toolholder must have a taper that mates to a Tapered
Holder mounted in the Tool radle. The Tapered Holder requires a slot to allow the
Toolholder to pass through. This same method is applicable to the motor’s design.
3.3 Tool and Media Specification
3.3.1 SM Tool older Specification
The motors are designed to grasp a ½ inch (12.7 mm) diameter steel shaft. Figure 6
shows the Toolholder dimensions required for the motor to operate properly. Notice
that the end of the Toolholder can be tailored to any needed configuration to attach to
various disk back-up pads, drill bits, router bits, grinding stones, etc. If desired,
PushCorp, Inc. can fabricate custom Toolholders, at an additional cost, based on
customer supplied drawings and specifications. To prevent interference between the
Toolholder and the ollet an 11° taper must be included in all Toolholder designs.
Toolholders should be manufactured from carbon or stainless steel with a hardness
less than Rc40. The surface finish on the Toolholder lamping Surface should be Ra
16 – 32. To accurately locate the Toolholder axially the front flat surface of the ollet
can be used. This means that the Toolholder lamping Surface and taper must be
shorter than the ollet depth. When using the ollet face for positioning some form of
compliance must be used on the Tool radle to prevent wedging the ollet in too
tightly, or damaging the motor bearings.

3.3.3 BT30 Tool older Specification
The ST -BT30 motor is designed to grip a BT30 toolholder. The BT30 toolholder is a
standard machine tool style and may be purchased from several sources including,
MS (www.msc.com), and J & L Industrial Supply (www.jlindustrial.com). The
ustomer can also make their own BT30 toolholder to handle special media (See
Figure 7 for toolholder dimensions). The toolholder must be equipped with a Parlec
(www.parlec.com) retention knob, part number 3003TRK, or equivalent. Figure 8
shows the Parlec retention knob with the required dimensions.

3.4 SM Collet Operation
The ollet for the SM motor is tightened and loosened manually. The Motor Shaft
must be held using the Motor Shaft Flats, while the ollet Nut is turned, see Figure
11. Turning the ollet Nut clockwise forces the ollet into the Motor Shaft causing it
to clamp around the Toolholder. To loosen the ollet, rotate the ollet Nut counter-
clockwise. If the ollet is to be removed, continue rotating the ollet Nut counter-
clockwise and the ollet Nut and ollet will come off together. The ollet is an ER
Series (DIN 6499 Form B) Size 20. The recommended tightening torque for the
ollet Nut depends on the bore diameter of the ollet. For ollet bore diameters
0.276 – 0.512 in. (7.0 – 13.0 mm) the recommended tightening torque is 60 lb.-ft. (80
N·m), and not to exceed 75 lb.-ft. (100 N·m). For ollet bore diameters 0.039 – 0.256
in. (1.0 – 6.5 mm) the recommended tightening torque is 24 lb.-ft. (32 N·m), and not to
exceed 30 lb.-ft. (40 N·m).
CAUTION: Tig tening toques greater t an recommended will permanently
deform t e collet cavity of t e tool older.
3.4.1 SM Collet Assembly and Removal
To assemble the ollet insert the ollet Groove into the Eccentric Ring of the ollet
Nut at the mark on the bottom of the ollet Nut. Push the ollet in while rotating the
ollet up, until it clicks in. See Figure 9.
To remove the ollet, first unscrew the ollet Nut from the Motor Shaft. After the
ollet Nut is unscrewed, press on the face of the ollet while simultaneously pushing
sideways on the back of the ollet until it disengages from the ollet Nut. See Figure
9.
Figure 9: SM ollet Assembly
and Removal

PUSHCORP, INC. 0605 / 1503 Servo Motor Series Manual 11
Improper assembly or removal of the ollet can permanently destroy the concentricity
of the ollet and may also result in a damaged ollet Nut.
NOTE: Only attac Collet Nuts wit correctly assembled Collets, to t e Motor
S aft! Never place t e Collet into t e Motor S aft wit out first assembling t e
Collet into t e Collet Nut.
NOTE: Never clamp oversized, or undersized, Tool olders! E.g., never use a
11-12mm Collet to clamp a 12.2mm Tool older. Always use t e
corresponding Collet for t e Tool older being used.
NOTE: Insert t e Tool older t e full lengt of t e Collet for best results, if
possible. However, never insert t e Tool older less t an 2/3 of t e Collet bore
lengt . Improper tool insertion can permanently deform t e Collet and will
result in excessive run-out.
3.5 Pneumatic Connection
All ST versions of the motor requires a dry, non-lubricated, filtered air supply, with a
minimum pressure of 90 psi (6.2 bar) and a maximum pressure of 100 psi (6.9 bar).
Failure to provide supply air to these specifications can degrade performance and will
void any warranty repairs concerning pneumatic components. If the supply air
pressure is too low then the unit will be unable to fully release the Toolholder.
Exceeding the maximum air pressure could result in permanent damage to the ST .
The pneumatic supply system should be configured as shown in Figure10 . A manual
or electrically operated valve may be used to energize the ST for Toolholder
release, but the valve must exhaust ALL line pressure when unenergized.
Push orp highly recommends the installation of a quick exhaust valve in the Supply
Line to the ST ; the quick exhaust valve should be mounted as close to the ST unit
as possible. This will minimize the distance exhaust air needs to travel, thus
decreasing the time needed for the unclamp cylinder to actuate. Pressure in the line
will cause internal components to come into contact. This will either cause the motor
not to spin, or cause very high internal forces, eventually friction welding components
together. A pressure sensor capable of sensing below 0 psi should be installed in the
supply line between the exhaust valve and the ST . Push orp recommends the
pressure sensor from IFM (PN: 7694); it has the capability to sense a pressure range
of -14.5 psi – 145 psi.

PUSHCORP, INC. 0605 / 1503 Servo Motor Series Manual 12
The ST and ST -BT30 motors are provided with ¼ inch and 6 mm diameter tubing
push-lock fittings for installation in the R 1/8 (Metric) ollet Unclamp Port located on
the top of the lamping Housing (See Figure 11). Remove the shipping plug and
install the desired size push-lock fitting. If another type of fitting is desired, unscrew
the existing fitting and replace it with any fitting having an R 1/8 (Metric) thread. Be
sure to use a thread seal product and do not over tighten the fitting.
The Unclamp Supply Line to the device should be 1/4 inch or 6 mm diameter flexible
polyurethane tubing. The tubing should be routed to the device such that there are no
kinks and that there is plenty of slack to allow for manipulator motion. Before
inserting the tubing into the ST air fitting, open the Shut-Off Valve to blow out any
contaminates which may be in the Unclamp Supply Line. The tubing can now be
pushed into the self-locking fitting located on the lamping Housing as shown in
Figure 11. harge the Unclamp Supply Line with compressed air and verify that there
are no air leaks and that there is a minimum of 90 PSI (6.2 bar) at the ST . If a
minimum air pressure cannot be achieved, then an auxiliary air compressor or
booster pump must be installed.
NOTE: Pus Corp recommends SMC quick ex aust valves, part number AQ-3-
40F-06-00 for 6 mm diameter tubing or part number AQ-3-40F-07-00 for 1/4 inc
diameter tubing.
NOTE: Pus Corp ig ly recommends t e use of flexible polyuret ane tubing
as opposed to nylon tubing. T is is because nylon tubing tends to crimp s ut
w en it is bent.
To remove the Unclamp Supply Line for service, make sure the air pressure is
discharged, then while pushing inward on the fitting's plastic ring, simultaneously pull
the tubing out. over or plug the self-locking fitting any time the Unclamp Supply Line
is not connected. This will keep contaminants from entering.

3.6 Electrical Connections
The 0605/1503 servo motor has two electrical connections, the Motor Power and
Motor Feedback (See Figure 12). If Push orp supplies the cables and amplifier the
tool should be easily connected to the amplifier. If the customer wishes to use their
own cables and/or amplifier the pin-outs for the Motor Power and Motor Feedback
connectors are shown below in Figure 12. The ollet release mechanism of the
0605/1503 Series relies solely on air pressure to operate; it requires no electrical
connections.
CAUTION: Do not run t e Motor Power Cable in close proximity to any
feedback or control cables because of possible electrical noise
problems.

3.7 Motor Cooling
The 0605/1503 Series have a compact, high speed, Servo Motor which requires
water cooling. The motor is designed to operate below a temperature of 176 F (80
). The optimal motor temperature range is 122 – 140 °F (50 – 60 ° ). The motor
contains cooling channels in the Motor Housing surrounding the motor stator. These
channels allow efficient removal of the heat. The coolant enters and exits the Motor
Housing through two Motor ooling Ports as shown in Figure 11. Either of these
Motor ooling Ports can be used as an input, the other would then become an output.
A closed-loop water cooling system must be used and requires a separate cooling
unit per spindle that circulates water through the Motor Housing to remove the heat.
Typical cooling units are comprised of a pump, liquid to air heat exchange, and a fan.
These units are commercially available from several manufacturers (e.g. Miller
oolmate 3, www.millerwelds.com). The cooling unit should be sized based on the
motor power output of the motor being used with an overall motor efficiency of 90%
and the motor load conditions. See section 4.0 of this manual for motor output ratings
for the motor being used. In the case of a closed-loop water cooling system, all of the
coolant is recirculated in the system, and no continuous supply of discharge is
required. Our standard offering is the Miller oolmate 3, which you can see in Figure
14, P I PN PAR03962. In this case the return line is the bottom connection; it is
recommended that a flow sensor is installed inline with this port and wired back as
part of the control circuit. Push orp recommends the IFM flow sensor (PN
SBG12IF0FRKG). This will ensure the coolant is circulating completely through the
motor and back to the cooler. Domestically, Push orp provides Miller’s pre-mixed
glycol base aluminum protecting coolant (Miller PN 043-809 – P I PN PAR04028).
Any coolant which matches the parameters of this coolant may be used.
