Product Description:

The MAF100D-0250-FQ-S2-RH0-35-H1 is a liquid-cooled asynchronous housing motor from Bosch Rexroth Indramat’s MAF IndraDyn Asynchronous Motors series. Designed for integration into automated machine tools and production cells, the unit uses flange and foot mounting together with a right-side power connector for straightforward installation in standard drive trains. Its 100 frame size with length code D provides a compact envelope, while the plain shaft suits belt or coupling transmission. High-speed bearings help limit vibration during continuous service, and the connector-style power lead supports orderly cable routing inside the machine.

The motor reaches a rated speed of 2500 rpm, maintained by a liquid cooling circuit that circulates coolant through the stator. This circuit uses a 1/4 inch connection thread, so installation can be completed with standard hydraulic fittings and a repeatable sealing interface. Axis control uses an EnDat2.1 interface with a single-turn absolute encoder that delivers 2048 increments per revolution, allowing precise commutation and position tracking. Because the encoder is absolute, position data is available immediately after power-up. The encoder electronics operate from a 7–12 V supply, which matches common drive controllers and supports stable feedback transmission over short cable runs.

The cast housing has an IP65 protection rating, which helps keep dust out and directs splashed fluid away from the windings. Insulation class F allows winding temperatures up to 155 °C, and reliable service is specified for ambient temperatures from 0 to 40 °C. The assembly meets vibration grade A according to DIN EN 60034-14, and winding code 0250 matches drive algorithms for torque linearity. There is no holding brake, so any required holding force must come from the drive or an external device. The shaft is supplied without a sealing ring, so the surrounding machine design must protect the output end when contamination could be present.
