CAUTION –Possible damage!
- Please note the wiring data on the specification and the permitted
mechanical loads (see technical data in the data sheet).
- Switch off the supply voltage before mounting and wiring the step-
per motor.
- Stepper motors must not be operated with mains voltage. Stepper
motors require special control units
- While press-fitting couplings or pinions on the motor shaft, the lat-
ter should be supported.
- Remove the PTFE tube only from the lead which you are just con-
necting (chapter 6.2.2).
- Never lift the motor by means of its cables or leads! Care for strain
relief when stripping or shortening the leads!
- Comply with EMC conform wiring (chapter 6.2.2).
- Do not open the stepper motor! If the casing is opened, the motor
may be damaged. Phytron's warranty does not apply if motors are
opened by the customer. When operating a motor that was as-
sembled improperly, danger to life could be caused by electric
shock.
- The customer must not carry out mechanical or electrical modifica-
tions of the motor. The warranty does not apply if the motor is mod-
ified by the customer without the manufacturer's permission
1.4 European Standards and CE Mark
When installed appropriately, space stepper motors fulfil the requirements of the EMC and
Low Voltage Directives. Space stepper motors are qualified to be marked CE and comply
with EN 60034-1 European Standard.
When wired correctly (see Fig. 5), space stepper motors fulfil the requirements of the EMC
Directive. Information concerning the connection of the motor cable to the control unit or
the power stage is given in the corresponding manuals.
According to the European Machine Directive, the stepper motor is only a part of a ma-
chine. Placing into operation is not allowed until the machine manufacturer takes appropri-
ate measures to ensure that the entire system fulfils the requirements of the applicable EU
Directives.

2 Space Stepper Motors
Phytron space stepper motors for in-vacuum and Cryo applications are precision drives
with protection class IP20.
Space stepper motors are manufactured, cleaned, tested and packed with great care and
accuracy. A 4-stage package protects the stepper motor against contamination, moisture
and mechanical damage.
On opening the packaging, several precautions must be observed to maintain the defined
stepper motor's specifications and functionality.

i
The two most important rules for handling space stepper motors:
- Do not touch the stepper motor with bare hands!
- Take care that no particles or moisture can get inside the motor
through openings.

2.1 Heating in Vacuum Environment
Normally, the heat generated by a stepper motor in a vacuum is largely dissipated by con-
duction through the mounting surface.
To avoid overheating the motor, the maximum specified temperatures must be taken into
account when determining duty cycles for setting the peak, run and stop (holding) current
values.

MA 1313-A001 EN 11
3 Packaging
A special 4-stage package –transport package, outer package, transport cover and pro-
tective film –keeps the space stepper motor from contamination, moisture and mechanical
damage.
3.1 Transport Package
The type of transport package depends on the motor type, e.g. a cardboard box with
moulded foam, bubble wrap or similar material protects the motor during transport.
3.2 Outer Package
The outer package is a gas-tight, evacuated 100% LDPE foil package with the rating plate
fixed. A desiccant bag and humidity indicator are enclosed.

Do not touch a space stepper motor with bare hands!
Wearing safety gloves helps to keep away finger sweat and oil residues
from the stepper motor. Such residues cannot be completely removed with
IPA and may need the motor to be returned to Phytron for cleaning.
- Before opening the protective film: Put on some safety gloves.
- After removing from the foil packaging the stepper motor has to be
stored in a clean box, clean room or closed container.

5 Mounting
CAUTION –Possible injury!
- Power down the installation area or the stepper motor control unit.
i
CAUTION –Possible damage!
The stepper motor's rotor is strongly magnetic. Foreign substances, which
penetrate through openings, could decrease motor function.
- Do not touch the space stepper motor with bare hands! Wear safe-
ty gloves!
- Therefore, take care when mounting the motor: metal or soft iron
particles must not penetrate through openings into motor or gear-
ing.
- When handling stepper motors, the environment should be kept
very clean. Penetrating foreign substances, dirt or humidity could
seriously damage motor function or cause breakdown. Keep away
metal particles from the motor! Space stepper motors should
only be handled in a very clean environment.
i
CAUTION –Possible damage!
When flanging the motor, axial or radial force effects on the shaft (e.g.
strokes) must be avoided. Lifetime of the ball bearings will be shortened by
all kinds of load or rough treatment.
- Do not exceed the maximum axial and radial loads!
Avoid high shaft loads, e.g. shock/transient forces. Use suita-
ble couplings.

6 Electrical Connection
Phytron space stepper motors are 2-phase stepper motors. The windings can be connect-
ed differently: 4-leads parallel windings or cold redundant
4-leads parallel windings
Cold redundant
8-leads / unipolar or bipolar
control mode
4-leads / serial windings
bipolar control mode
5-leads / unipolar control mode
6-leads / unipolar control mode
Fig. 6 : Connection scheme for Phytron space stepper motors

phytron
MA 1313-A001 EN 19
8-leads stepper motors have two leads from each of the four motor windings (see Fig. 6).
These motors can be driven by all types of control units in bipolar and unipolar operating
modes.
4-leads stepper motors (windings parallel or serially connected (see Fig. 6) are designed
for bipolar operation mode.
Cold redundant stepper motors are designed for reliable operation within a drive system
(see Fig. 6).
Bipolar operation mode –parallel or series winding connection
Low control pulse frequency: When operated with maximum allowable phase current
(see table below), with both connection modes the same motor torque is generated.
With rising frequency, the torque drops off sooner with serial windings.
Reason: The motor's inductance is four times higher (compared to unipolar operation
or bipolar operation with parallel windings).
Operation with low control pulse frequencies
The motor has up to 40 % more torque in the bipolar mode (compared to unipolar control)
with the same phase current, at low frequencies.
5-lead or 6-lead stepper motors (Fig. 6) can be driven by unipolar control units.
The cable cross section for the connection leads should be selected according to the
cable length. Please follow the advice in the stepper motor power stage manual.
6.1 Maximum Allowable Phase Current
The motor rating plate has the rated phase current [A] as the last digits of the motor's type
number.
Example: phySPACE 25-2-1,2-Ti-red motor size 25, length 2, 1.2 A rated current
The rated current is the maximum allowable current at full step operation, at bipolar con-
trol mode, with parallel-connected windings (standard).
