Product Description:

The MAF100B-0250-FQ-M2-RH0-05-N1 is a liquid-cooled asynchronous housing motor produced by Bosch Rexroth Indramat within the MAF IndraDyn Asynchronous Motors series. As a housing motor, it integrates a coolant jacket so waste heat is taken away from the stator, allowing continuous torque delivery in compact automation cells. Deployed on indexing tables, gantry axes, or spindle drives, the unit provides regulated rotary motion where ambient airflow is limited and electrical noise immunity is required by modern feedback loops.

The motor reaches a rated speed of 2500 rpm. An enclosure protection rating of IP65 shields the stator windings from airborne dust and low-pressure water jets, so it can be mounted near cutting fluids or particulate processes. Heat is removed through liquid cooling, and coolant is introduced through a 1/4-inch thread that mates with standard factory manifolds. Position data come from an EnDat interface, and the built-in EnDat2.1 protocol transmits absolute position plus diagnostics to the drive controller. Resolution is 2048 increments per revolution, enabling fine velocity control even during low-speed creep. The absence of a holding brake reduces inertial load and simplifies maintenance, while conformity with DIN EN 60034-14 limits vibration to class A, protecting neighboring sensors.

Electrical power for the encoder electronics is provided at 7-12 V, matching common auxiliary supply rails in control cabinets. The housing attaches with flange mounting, which centers the 100 mm frame on gearboxes or machine plates without alignment shims. Class F insulation lets the windings tolerate up to 155 °C, extending service life when liquid flow is reduced. A plain shaft transmits torque directly into belt pulleys or couplings, and no shaft sealing ring is fitted. The motor uses a standard bearing set and is intended for ambient temperatures between 0 °C and 40 °C.
