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. 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
The "DA - W" series electric motors are 4-pole three-phase asynchronous motors. These motors
are liquid-cooled (water-based coolant) and, due to the efficient cooling system, they have a high
torque and power density with a high degree of protection. Since there is no fan unit, the noise
emissions from the motor are significantly reduced.
When operated with a motor-controlled pulse converter, the speed and position of these motors
must also be controlled; they are therefore ideal for applications on tool machines and production
machines (e.g. printing and plastic).
2.2 Items supplied
The delivery is put together on an order-specific basis.
• The carrier must be immediately notified of any damage caused during transit.
• On receipt of delivery, please make sure that the ratings and motor type agree 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.
