Product Description:

The MAF130B-0250-FR-S6-HG0-05-N1 asynchronous housing motor is manufactured by Bosch Rexroth Indramat as part of the MAF IndraDyn Asynchronous Motors series. It is intended to drive conveyors, spindles, and indexing tables in automated lines where tightly regulated speed and high thermal stability are required. The 130 mm frame fits installations that need compact overall dimensions while still supporting high continuous torque. This makes the motor suitable for direct mounting on machine frames and gantry axes where stable operation and predictable heat removal are important during repeated motion cycles.

Thermal management is provided by liquid cooling, delivered through an enclosed rapid-action coupling with a nominal diameter of 1/4 inch. Winding code 0250 gives the rotor a rated speed of 2500 rpm, which suits medium-speed machining and handling tasks without unnecessary overspeed. Position feedback is supplied by a single-turn absolute encoder that communicates through EnDat2.1 and provides 2048 increments per revolution, allowing accurate closed-loop control for both speed regulation and positioning. The encoder receives power through a 7–12 V line routed in a 15 m hybrid cable. Because the motor is supplied without a holding brake, any load that must remain fixed at standstill requires external mechanical restraint.

During installation, the unit is secured by flange mounting, and the plain shaft uses a shaft sealing ring to help maintain the IP65 enclosure. Electrical power enters from the B-side through a turnable terminal box, which helps cable routing when space around the motor is limited. Continuous operation is allowed in ambient temperatures from 0 to 40 °C, and the class F insulation system resists thermal aging under normal service conditions. Internal balancing meets vibration grade A, which helps limit vibration transferred to nearby machine components in accordance with DIN EN 60034-14. The coolant circuit and the frame length B help keep stator temperature more even across the housing during sustained load.
