Product Description:

The MAF130B-0250-FQ-S2-BH0-05-N2 is an asynchronous housing motor produced by Bosch Rexroth Indramat within the MAF IndraDyn Asynchronous Motors series. The unit is a liquid-cooled, flange-mounted drive element intended for precise speed regulation in automated machinery that demands continuous torque without large magnetic detent. Its 130 mm frame and plain shaft let it couple directly to gearboxes or pump loads, while the B-side power connector simplifies cable routing inside compact control cabinets.

The motor’s heat is removed through liquid cooling; coolant is fed and returned via a 1/4-inch connection thread built into the housing, so enclosure temperature stays stable even under peak load. Rotor position feedback is handled by a single-turn absolute encoder that communicates through the EnDat2.1 interface. With 2048 increments of resolution and a 7–12 V supply, this feedback system supports fine speed loops and accurate speed regulation on compatible drive controllers. The stator uses winding code 0250 and is rated for a nominal speed of 2500 rpm, allowing the drive to synchronize with standard industrial frequency converters in applications that need stable continuous operation without overspeeding.

A cast housing sealed to IP65 keeps dust and water jets out, so the motor can be mounted in washdown zones when coolant hoses are properly routed. Operation is specified from 0 to 40 °C, matching most electrical cabinets without additional HVAC. Windings with Class F insulation permit temperatures up to 155 °C before thermal limits are reached. The rigid flange mounting pattern, B-length frame, and B-side connector provide clear orientation for mounting and cable routing, while the lack of a shaft-sealing ring reduces friction where fluid ingress at the output end is not a concern. Standard bearings support axial and radial loads typical of belt-driven or direct-coupled applications, and the motor ships without a holding brake.
