Product Description:

The MAF100C-0250-FQ-S2-AK0-05-A1 is an industrial motor assembled by Bosch Rexroth Indramat for the MAF IndraDyn Asynchronous Motors series. Designed for integration on production machinery, it converts electrical power into controllable mechanical rotation and supports closed-loop speed control in automated lines. The unit fits a 100-frame housing with length code C, attaches by a flange, and carries its power connector on the A-side to simplify cabinet wiring. An A-side fixed bearing supports radial loads while the internal liquid channels stabilize temperature during high-duty cycles.

Heat is removed through liquid cooling that circulates coolant through a dedicated connection thread, and the inlet and outlet use 1/4 inch ports so standard hydraulic fittings can be used without adapters. Rotor position is monitored by a single-turn absolute encoder that resolves 2048 increments per revolution and communicates over the EnDat2.1 interface, allowing precise feedback when paired with a compatible drive controller. The encoder is powered from 7–12 V supplied by the drive. With its IP65 housing, the motor resists dust ingress and low-pressure water jets, permitting installation near machining fluid or airborne particulate sources. The motor is supplied without a holding brake, so static positioning must be maintained by the drive itself.

The motor can run up to 2500 rpm with winding code 0250. Its shaft is balanced with a half key to comply with the DIN EN 60034-14 vibration limit of grade A. An elastomer sealing ring around the keyed shaft helps keep coolant and contaminants out, and Class F insulation allows winding temperatures up to 155 °C under continuous duty. Operation is specified between 0 °C and 40 °C ambient, and the flange interface plus connector-based power lead simplify removal for service without disturbing plumbing.
