Motor design with rare earth magnets:
Please be aware of the following risks in the vicinity of a retracted or exposed rotor with a
strong magnetic field:
•People with electronic or metallic implants (e. g. cardiac pacemakers, hearing aids,
plates or pins) are at risk, if the distance between the implant and the magnetic pole
is less than 0.5 m.
•Due to the strong attraction forces exerted on ferromagnetic parts there is a risk of:
oCrushinginjuries
oDamage to measuring and assembly tools, credit cards, watches etc.
oContamination of the rotor assembly due to attracting metal debris or powder.
Thermal hazard:
Caution, risk of burns!
The surface temperatures on the motors may exceed 70 °C. If necessary, fit guards!
Temperature-sensitive parts, e.g., normal cables or electronic components, must not be
placed on or fixed to the hot surfaces.
Thermal overloading can destroy the winding and the bearing and can cause
demagnetisation of the rare-earth magnets. A thermal sensor should be used to monitor
the temperature.
1.3 Prohibition of unauthorized modifications and changes
For safety reasons, unauthorized modifications and changes to the electric motor are not
permitted. If such modifications/changes are necessary, please contact the motor
manufacturer.

2 Operating conditions
2.1 Product description
The "DSD" and “DSD2” series electric motors are 8-pole three-phase synchronous motors with rare-
earth magnets. These motors are capable of excellent acceleration performance thanks to the low inertia
of the rotor.
When operated in conjunction with a motor-controlled pulse converter, these motors respond extremely
well to speed and position control and are highly dynamic. Therefore, they are ideal for applications
associated with machine tools and production machines (e. g. printing, packaging, textile machinery), as
well as handling devices and robots.

2.5 Transport, bearing lock, intermediate storage
Transport:
The permitted environmental conditions which affect the motor during the transport must be
taken from DIN EN 60721-3-2 (class 2K2/2M1). Contrary to the DIN, a reduced
temperature range of – 15 °C to + 60 °C is permitted.
Suitable lifting tackle must be used, e. g. belt webbing, loop belts etc. If provided, the lifting
lugs of the motor can be used for lifting.
The motor connectors are not allowed to be used for securing for transport or as lifting
eyes.
The regulations of the respective countries must be adhered to during transport. Lifting
devices and transport and load suspending devices must comply with the relevant
regulations.
For information on weight of the single motors, please refer to the technical documentation that
accompanies the product.
The motor shaft and the connection surfaces must be protected against corrosion. The motor may only be
transported with a shaft protection cover; damage to the motor shaft must be avoided.
Intermediate storage:
If a motor is not to be commissioned immediately after delivery, it should be stored inside a building in a
dry, dust-free and low-vibration room (V
eff
≤0.2mm/s).
The electric motors should be stored at as uniform a temperature as possible, not outside of the
temperature range -15 to +60 °C, for no more than two years. Elevated storage temperatures within the
framework of the working temperature accelerate the rate at which seals and bearing grease deteriorate
and therefore have a negative impact on the service life even before the unit has been commissioned.
Direct exposure to incident solar radiation, UV light and ozone also lead to an ageing of the gaskets and
must be avoided!
Please note that the warranty periods commence from the date of delivery. For this reason, we
recommend that storage periods be kept to a minimum.
Should nevertheless a longer storage be necessary, the environmental conditions acc. to DIN EN 60721-
3-1 (class 1K2/1M1) have to be observed. Contrary to the DIN, an expanded temperature range of –
15 °C to + 60 °C is permitted.
2.6 Installation conditions, cooling details
Surroundings:
The motor can be installed in roofed rooms in dusty or damp environment and under normal climatic
conditions.
Unless alternative arrangements have been made, the motor is designed by default for the following
climatic conditions:
•Ambient temperature 0 °C to 40 °C
•Installation height ≤1000 m above sea level
•Relative humidity 5 % to 85 %
All other allowed application conditions have to correspond to DIN EN 60721-3-3 (class 3K3/3Z12).
It is absolutely imperative to comply with these climatic conditions when installing the unit.
Aggressive, corrosive, abrasive and plastic-dissolving solutions should be kept well away from the motor
and the air that is used to cool it.
Consultation with the motor manufacturer is essential in the case of installation outdoors.

TAM00721 10
DSD-028 / DSD-036 / DSD2-028 / DSD2-036 04/2013
Three-phase-synchronous motor English
Air cooling:
For ambient conditions, see Section 2.4 and the technical documentation that accompanies the product.
Cooling method IC 410 – Self-cooling without a fan.
The following must be observed:
•The installation conditions must not impair thermal convection and radiation.
•The cooling air used for forced ventilation must be able to flow in freely and the hot air must be able
to flow out freely. The hot exhaust air must not be sucked back in.
•A clearance of at least 100 mm must be observed in relation to neighboring machine parts.
•If installed in very dirty locations, the housing surface and airways must be cleaned regularly.
flange connection:
By connecting the motor to the mounting surface, a part of the motor loss performance is lead away via
the flange. The dimensions of the mounting surface based on their axis height are listed in
table 1. This information provides minimum values for the safe heat dissipation via the motor flange
surfaces.

Table 1: Mounting surfaces
The heat dissipation conditions approve on larger mounting surfaces. An insulated mounting of the
motors is not permitted.
2.7 Balancing, output elements, vibration
Do not subject the shaft or bearings to impacts!
On mounting and dismounting output elements, it is not permitted for any axial forces to be
applied to the motor.
The generally applicable measures for the protection of output elements against physical
contact are to be followed.
If a motor is to be commissioned without output elements, measures must be taken to
ensure the key is not flung out.
Balancing
In the optional design, the rotors are dynamically balanced with a half key (in accordance with
DIN EN 60034-14 / ISO 8821 / ISO 1940).
Output elements:
On mounting the output element, pay attention to the related type of balancing. The output elements must
themselves be balanced in accordance with ISO 1940.
Suitable jigs are always to be used for fitting or removing output elements (e.g. clutch disk, gear, pulley).
• Use the threaded hole in the end of the shaft.
• When pulling, use intermediate washers to provide the shaft with mechanical protection.
• When hoisting heat up the drive elements if required (max. permissible temperature at shaft end
150°C).

TAM00721 11
DSD-028 / DSD-036 / DSD2-028 / DSD2-036 04/2013
Three-phase-synchronous motor English
Attention:
• On shaft versions without a key, the output elements are to be fastened to the output shaft with the
aid of suitable clamping sets.
• On shaft versions with a key, it must be ensured that the output elements rest on the shaft
shoulder. Note: The chamfer or radius on the output element and the shaft radius on the shoulder
must be matched.
• Is the tapped hole in the end of the shaft used for axial securing of output elements (e. g. belt pulley),
the maximum tightening torque acc. to following table 2 must not be exceeded.

M5 2,2
M8 10,0
M10 19,0
M12 33,0
Table 2: Tightening torque for safety screw S of a belt pulley
appropriate measures for securing screw must be applied
Vibration:
The site vibration response of the system, which is determined by the output elements, the
mounting conditions, the alignment, the installation, and the effects of external vibrations,
may cause the vibration values at the motor to increase.
In the interest of reliable motor operation and a long bearing service life, the permitted
vibration values in accordance with EN 60034-14 should not be exceeded. Under certain
circumstances, the rotor may need to be fully balanced with the output element (in
accordance with ISO 140).
The vibration value after mounting must not exceed the permitted rates of acceleration
(comp. Section 2.4 )
Where there are deviations from normal operation – e. g., rise in temperature, noises,
vibration – switch off the motor. Identify the cause and, if necessary, contact the
manufacturer.

isolated and there is no potential.
When in operation, electric potential can be found at the motor contacts and at the motor
windings. Never touch these modules / elements while the motor is in operation.
Installing and uninstalling safety devices:
The electric motor must not be commissioned without first mounting the safety devices.
The motor must be put out of operation when installing and dismantling components and
systems which are provided for monitoring the motor for safe operation.
Danger on physical contact:
Make sure that the electric motor has come to a standstill and is secured against accidental
restarting before you touch it.
Only touch the output shaft when it is electrically isolated and the motor has come to a
standstill. Otherwise there is a risk due to the rotating rotor.
Danger of burns! Never touch the motor housing when the motor is running at rated load.
The surface temperatures on the motors may exceed 70 °C.
4.2 Checks prior to commissioning

4.3 Commissioning, operation
Note on brake function (if present):
The brake is designed as a holding brake with an emergency stop function.
(power failure and emergency stop)
It must not be used as a working brake.
Commissioning must be carried out exclusively by qualified personnel.
Please refer to the commissioning instructions for the converter and the cooling system.
Checks during commissioning:
• Release the brake, if necessary.
• Have all the modules of the motor such as the brake, encoder, etc. been checked and are they in
compliance with the conditions of use?
• Have all electrical connections been made correctly and tightened? (observe wiring diagrams, see
Section 7 and respectively the enclosed wiring diagrams).
• Have all protection measures which eliminate the possibility of physical contact with live parts, hot
surfaces, rotating and moving parts been followed and are these measures fully functional?
• Have all output elements been mounted and adjusted in accordance with the manufacturer's
instructions?
• Are measures in place to ensure that the maximum permitted speed n
max
of the motor cannot be
exceeded? The maximum permitted speed n
max
is the highest permitted operating speed for short-time
duty.
Checks during operation:
• Listen out for unusual noises.
• If scraping, scratching, grinding, or other similar noises occur, stop the drive immediately and locate
the cause.
• Check the motor surface and connection cables for dirt, e.g. layers of dust, oil deposits, dampness
and leaks etc.
• Check the maintenance intervals.
4.4 Malfunctions in operation
Safety instructions:
Troubleshooting and rectification must only be performed by qualified personnel.
Do not disconnect any of the safety devices – even during test runs.
Only disconnect and connect electrical cables when electrically isolated and secured.
Observe the 5 safety rules for "Isolation" (comp. Section 3.3).
Beware of hot surfaces!
In case of malfunctions in operation always
•Refer to the operating instructions for the machine/system.
•Refer to the operating instructions for the converter.
•If necessary, contact the manufacturer of the motor or converter.

5 Inspection and maintenance
Working on the electric motor:
Work must not be carried out on the electric motor until the motor has come to a standstill,
is electrically isolated, de-pressurized and has cooled down. All connections, such as
screws on the motor that were loosened must be tightened again after the inspection and
maintenance work.
When carrying out work on the motor, please observe the technical instructions and notes in
the respective sections in these Commissioning and Maintenance Instructions.
When carrying out maintenance work, observe all safety instructions which also apply to the
commissioning of the motor (see Section 4.1).
Attention!:
If the optional holding brake is fitted, this brake must not perform a safety function during
work on the motor (e. g., retaining loads)!
5.1 Inspection
Depending on the severity of soiling on site, cleaning will have to be carried out regularly to guarantee
the continuous adequate dissipation of heat. The flow rate and the pressure ratio of the cooling system
must be checked.
If an optional brake is fitted, wear limits are specified (e. g., maximum permissible operating air gap,
maximum number of emergency braking operations). The actual degree of wear on the brake must be
checked at regular intervals. When the permissible wear limits have been reached, the brake must be
replaced (see Section 5.2).
If an optional shaft sealing ring is used, it must be checked at regular intervals to ensure it is functioning
correctly (leakage).
5.2 Maintenance
The service life of the bearings and sealing elements can differ greatly depending on the operating
conditions, (e. g. operating mode, temperature, speed and load).
In the case of trouble-free operation, we generally recommend the following maintenance procedures:
• Replacement of the bearings after 20.000 running hours (the bearings are designed for a calculated
service life of 20.000 running hours)
• Replacement of the shaft-sealing ring after approximately 5.000 running hours, if present and if no
leaks have been detected during previous inspections
If an optional brake is fitted, it is essential that it is replaced when its wear limits are reached.
The maintenance work is to be undertaken by Baumüller or a specialist organization authorized by
Baumüller.
Caution!
The specifications of the technical instructions TABG 30026 must be followed during
maintenance and servicing on motors which are used for safety-oriented applications.
6 Disposal
The motor must be disposed of in accordance with the relevant national and local regulations within the
framework of the normal recycling process.
The encoder electronics (if provided) must be disposed of in the proper manner as electronic scrap.
