Product Description:

The MAF130B-0250-FQ-S2-AH0-05-H1 is a liquid-cooled asynchronous housing motor built by Bosch Rexroth Indramat within the MAF IndraDyn Asynchronous Motors series. Designed for flange mounting inside tight machine frames, the unit provides constant torque delivery for automated production lines and test rigs. It integrates into liquid circuits to remove heat directly from the stator, allowing higher continuous output than air-cooled motors of similar size. In industrial automation, the motor converts electrical energy into rotary motion that can be precisely regulated by an inverter through its integrated absolute position feedback.

The motor relies on liquid cooling carried through an internal jacket and routed by a connection thread on the A-side housing. The thread has a nominal diameter of 1/4 inch and accepts standard hydraulic fittings. With this thermal path, the stator can maintain its rated speed of 2500 rpm without derating. An enclosure rating of IP65 shields the frame from dust and water jets, so the unit can be installed near coolant manifolds. Rotor position is reported by a single-turn absolute encoder that communicates over EnDat2.1 at a supply of 7–12 V, and its feedback grid contains 2048 increments for fine speed regulation. The motor is supplied without a holding brake, and power is routed through a connector on the A-side.

Bearings graded as High Speed support rapid acceleration while keeping vibration within level A. The mounting flange complies with DIN EN 60034-14, helping maintain repeatable alignment on standardized gearboxes. Insulation rated to class F accommodates winding temperatures up to 155 °C, and the motor operates in ambient temperatures from 0 to 40 °C. It uses a plain shaft without a shaft sealing ring to minimize drag, and frame size 130 with length code B fits compact housings. The motor uses winding code 0250 for the electrical variant intended for IndraDrive inverters.
