Product Description:

The MAF100B-0250-FQ-S2-DH0-35-H4 is an asynchronous housing motor produced by Bosch Rexroth Indramat and assigned to the MAF IndraDyn Asynchronous Motors series. It is intended for integration into precision drive trains where regulated speed and continuous torque are required on production machines and automated test equipment. As an asynchronous motor, it works with a matched drive controller to maintain stable output as load conditions change. This operating principle suits machine sections that run for long periods and require predictable thermal behavior.

Liquid cooling is implemented through a 1/4-inch connection thread on the right side of the frame, and this threaded coupling links the external chiller circuit directly to the stator jacket so waste heat is removed continuously. The cooling interface sits beside a rotatable terminal box that brings the power conductors in from the right, allowing flexible cable routing during installation and permitting the cable outlet direction to be adjusted without moving the motor. The motor has a rated speed of 2500 rpm and uses high-speed bearings that support the elevated shaft velocity. Position feedback is provided by a single-turn absolute encoder over the EnDat2.1 interface with a resolution of 2048 increments and a 7 to 12 V supply. The housing has an IP65 protection rating, and the motor comes without a holding brake, which reduces axial length and inertia. The shaft exits the housing without a sealing ring, so external guarding must prevent process fluid ingress.

The mounting interface uses flange and foot mounting, so the unit can be fastened either through the end shield or the base to fit existing machine layouts. The motor has a frame size of 100 and a frame length of B, while winding code 0250 identifies the electrical layout used for this version. Insulation class F permits winding temperatures up to 155 °C, and vibration grade C supports balanced operation on precision machinery. Ambient operation is permitted from 0 °C to 40 °C. Frame length B affects the motor's axial envelope, which is useful when space is limited around couplings or guarding.
