TAM 00682 6
DSC 045-100 07 / 2012
Three-phase synchronous motor English
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:
o Crushinginjuries
o Damage to measuring and assembly tools, credit cards, watches etc.
o Contamination of the rotor assembly due to attracting metal debris or powder.
Thermal hazard:
Caution, risk of burns!
The surface temperatures on the motors may 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 lead to the
demagnetization 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.
No safety devices may be dismantled or decommissioned when operating the electric
motor.
2 Operating conditions
2.1 Product description
With its new DSC 45-100 series, Baumüller is making the torque motor servo-ready.
In developing this series, the focus was on improving ratings in order to achieve a higher torque
density while also drastically reducing the volume of the unit. The typical servo speed range of up
to 4,000 rpm is, however, still covered. The new DSCs are up to 30 % more compact than
conventional servo motors.
The motors of the DSC 45-100 series feature a smooth housing surface to protect against soiling.
These motors are particularly easy to mount and offer a high protection type.
2.2 Items supplied
The delivery is put together on an order-specific basis.
• The carrier must be notified immediately of any damage caused during transport.
• On delivery, please check that the ratings and type of the motor supplied correspond with the
order data. In the event of apparent defects or incomplete delivery, the appropriate Baumüller
office or the Baumüller head office in Nuremberg should be notified immediately.
In both of the above cases, commissioning must not take place until the error has been rectified by
a specialist.
