Product Description:

The MAF100C-0250-FQ-M2-AK0-05-A1 belongs to the MAF IndraDyn Asynchronous Motors series from Bosch Rexroth Indramat. It is a liquid-cooled asynchronous motor for continuous-duty automation in drive lines built to DIN EN 60034-14. Because it uses an asynchronous rotor principle, it suits machinery that runs for long periods under changing load conditions. The unit uses frame size 100 with length code C, and its shaft has a keyway with half-key balancing for standard couplings. A fixed bearing on the A side supports axial forces, while a shaft sealing ring helps keep coolant and dust out during operation.

At a rated speed of 2500 rpm, the motor delivers constant torque across typical conveyor or spindle profiles. Heat produced by the stator is removed by liquid cooling, and the coolant enters through a factory-machined 1/4-inch connection thread that supports closed-loop plumbing. Position data come from a multi-turn absolute encoder that supplies 2048 increments per revolution over the EnDat2.1 interface and operates on 7 to 12 V. This feedback allows the connected drive to monitor shaft position during motion and after restart without an added external transducer. Electrical power reaches the windings through a connector on the A-side, keeping access on one face of the machine. The housing carries an IP65 rating, which helps keep dust and water jets away from live parts. The motor is supplied without a holding brake, so any static load that must remain fixed requires an external restraint or drive-controlled holding torque.

Internal insulation is graded F, permitting winding temperatures up to 155 °C while meeting vibration level A requirements. This thermal class supports reliable operation during repeated starts and sustained loading in automated equipment. Continuous operation is allowed in ambient temperatures from 0 to 40 °C, after which derating is recommended. The flange mounting interface aligns the motor with gearboxes or machine frames, and this arrangement helps maintain coupling alignment where vibration and bearing load must be controlled. Winding code 0250 indicates the electromagnetic set used by this model.
