Product Description:

The MAF100D-0250-FQ-S2-BL0-35-N3 belongs to the MAF IndraDyn Asynchronous Motors series manufactured by Bosch Rexroth Indramat. It is specified as a liquid-cooled asynchronous housing motor and serves as a drive element for industrial automation equipment that needs steady speed regulation while maintaining a compact thermal footprint. By channeling coolant through integral passages in the housing, the unit removes heat directly from the stator so it can deliver continuous torque under confined mounting conditions.

In this design, liquid cooling is routed through a 1/4 inch connection thread located on the motor jacket, simplifying connection to plant chillers. The cooling scheme works with standard bearings and keeps the rotor within vibration grade B. Feedback is handled by a single-turn absolute encoder that supplies 7–12 V and communicates via an EnDat2.1 interface at a resolution of 2048 increments for position control. The rotor is balanced with a half key, and output torque is transferred by a shaft with a keyway. No shaft sealing ring is fitted, so external sealing must be provided when fluids are present. The winding code 0250, frame size 100, and length code D identify the electrical stack. The motor is supplied without a holding brake, so static load retention must be provided by the drive or the machine.

Mechanical attachment uses flange and foot mounting, allowing the 100-frame housing to bolt to base plates or machine faces while keeping the power connector on the B-side for straightforward cable routing to the drive cabinet. The enclosure achieves IP65 ingress protection and uses insulation class F, so the windings may operate up to 155 °C while the ambient temperature remains between 0 °C and 40 °C. At a rated speed of 2500 rpm, the motor matches many pump or spindle requirements, and compliance with DIN EN 60034-14 covers vibration and balancing tolerances.
