Product Description:

The MAF100D-0250-FQ-M6-EG0-05-A1 is manufactured by Bosch Rexroth Indramat as part of the MAF IndraDyn Asynchronous Motors series. It is a liquid-cooled asynchronous housing motor intended for automated stations that run for long durations at stable speed. Frame size 100 and frame length code D keep the envelope moderate, while flange mounting provides a rigid interface to machine beds. The motor complies with DIN EN 60034-14 for vibration behavior. A plain shaft with a shaft-sealing ring suits direct-coupled loads. Power conductors enter on the A-side through a turnable terminal box, allowing cable routing to match cabinet orientation.

Thermal management relies on liquid cooling. Coolant is introduced through a connection thread that uses a 1/4 inch port, so standard fittings can be applied without adapters. The motor delivers its rated performance at 2500 rpm, enabling drive controllers to maintain process speed without overshoot. An enclosure rating of IP65 blocks dust and water jets, protecting the class F windings and the vibration level A rotor assembly. Position feedback is supplied by a multi-turn absolute encoder for Ex-type motors that uses EnDat2.1 communication. It offers 2048 increments and operates from a 7–12 V supply, which helps the axis recover position data after power loss.

A fixed bearing on the A-side supports axial loads while maintaining alignment with the plain shaft, and class F insulation lets the winding code 0250 carry continuous current without thermal degradation. The encoder cable can span up to 15 m, which helps when the drive electronics are mounted away from the motor. The motor operates in ambient temperatures from 0 to 40 °C, matching common factory conditions. The motor is supplied without a holding brake, so external locking devices must secure vertical axes when power is removed.
