Product Description:

The MAF225C-0100-FQ-S2-HH0-35-N1 is a liquid-cooled asynchronous housing motor manufactured by Bosch Rexroth Indramat within the MAF IndraDyn Asynchronous Motors series. Intended for continuous-duty automation, the unit converts three-phase electrical energy into mechanical rotation for pump stations, processing spindles, or test rigs that require steady torque at moderate speed. Integrated feedback and a sealed coolant jacket allow the motor to operate inside enclosed machine frames where ambient airflow is limited while still providing accurate position data to the drive controller.

The thermal system uses liquid cooling circulated through a 1/2 inch connection thread, pulling heat directly from the stator laminations and helping stabilize winding temperature during full-load operation. A single-turn absolute encoder operating over EnDat 2.1 delivers 2048 increments of resolution and accepts a regulated supply of 7–12 V, enabling precise closed-loop speed regulation. Power enters through a turnable terminal box on the B-side of the housing, and the enclosure has an IP65 rating to protect internal components from dust and water jets. Under rated conditions, the plain shaft reaches 1000 rpm, which suits pump and spindle duty cycles while remaining below critical vibration points.

A standard bearing set carries radial loads, and the assembly can be mounted by flange or foot on the machine base. Frame size 225 with length code C provides a compact envelope relative to its torque capacity. The windings use code 0100 and class F insulation, supporting a 155 °C thermal limit. Operation is permitted from 0 to 40 °C, and vibration level A meets the balance criteria of DIN EN 60034-14. Delivered without a holding brake and without a shaft sealing ring, the motor requires external load holding when the axis must remain fixed at standstill.
