Product Description:

The MAF100D-0250-FQ-M2-AH0-35-N1 belongs to the MAF IndraDyn Asynchronous Motors series from Bosch Rexroth Indramat. As a liquid-cooled asynchronous housing motor, it drives conveyor sections, presses, and similar axes that need constant torque in compact machine frames. The housing format suits installations where coolant is already available and floor space is limited. The unit follows DIN EN 60034-14 for vibration limits and supports flange or foot mounting in vertical or horizontal orientations.

This motor delivers a continuous torque of 75 Nm at a rated current of 45.8 A and produces 19.6 kW of mechanical power while running at a nominal speed of 2500 rpm. The motor has an IP65 enclosure that resists dust and water jets, and it uses a plain shaft without a shaft-sealing ring to reduce friction. Standard bearings support the rotor, and vibration level A helps keep structure-borne noise low during operation. Liquid cooling circulates through a 1/4-inch threaded connection on the A side, which helps keep the winding within its F-class insulation limit at ambient temperatures from 0 °C to 40 °C. Three pole pairs establish the rotating field, and position feedback comes from a multi-turn absolute encoder with 2048 increments over an EnDat 2.1 interface powered by 7 to 12 V.

For short bursts the motor can reach 177 Nm, a reserve supported by a rotor inertia of 0.032 kg·m² that balances quick speed changes with mechanical stability. A torque constant of 1.55 Nm/A relates phase current to shaft torque, and the thermal time constant is 10 minutes so overload heat can dissipate through the coolant between load peaks. Because the motor is supplied without a holding brake, external clamping must secure stationary loads, and the housing weighs 88 kg. The installed mass requires a rigid base and secure mounting surfaces.
