Product Description:

Bosch Rexroth Indramat manufactures the MAF130B-0250-FQ-S2-BH0-35-H1 as part of the MAF IndraDyn Asynchronous Motors series. This model is a liquid-cooled asynchronous housing motor intended for high-duty machine axes in packaging, forming, or process lines where sustained output and compact installation are important. Its aluminum housing contains internal coolant passages that transfer heat to an external chiller rather than the surrounding air, helping the motor operate steadily in enclosed spaces while reducing the thermal load on nearby electronics. Because heat is removed by the coolant circuit instead of cabinet air, the motor is suitable for layouts where available airflow is limited.

The motor uses winding code 0250 and reaches a rated speed of 2500 rpm, which serves as the reference point for drive tuning and normal operation. Position feedback comes from a single-turn absolute encoder that communicates over EnDat 2.1 and resolves rotor angle into 2048 increments; the sensor operates from 7–12 V supplied by the inverter, allowing the drive to monitor shaft position during closed-loop control. High-speed bearings support operation at that shaft speed, and liquid cooling enters the housing through a threaded port with a diameter of 1/4 inch for standard hoses. Class F insulation supports winding temperatures up to 155 °C, vibration level A limits imbalance, and power is connected on the B-side; the motor is supplied without a holding brake.

Mechanical integration uses flange and foot mounting on a 130 mm frame with B length, which provides a consistent axial dimension and high radial stiffness for machine installation. This mounting arrangement supports both rigid machine-face attachment and base mounting on machine frames. The shaft is a plain shaft without a shaft sealing ring, so external guarding is required if fluid ingress along the journal is expected. The housing is rated IP65, and the assembly can operate in ambient air from 0 to 40 °C without derating when the cooling circuit is in use. Compliance with DIN EN 60034-14 confirms the stated vibration grade.
