Product Description:
The MAF100B-0250-FQ-S2-BH0-05-H4 asynchronous motor is manufactured by Bosch Rexroth Indramat within the MAF IndraDyn Asynchronous Motors series. Classified as a liquid-cooled asynchronous housing motor, it is intended to drive continuous-duty axes such as conveyors and presses in automated production lines. In this role, the motor converts electrical input into stable rotary motion for equipment that runs for long periods under steady process demand. By combining an integrated absolute encoder and sealed power connectivity, the unit links directly to IndraDrive controllers for closed-loop speed and position regulation in industrial automation equipment.
Thermal management relies on liquid cooling, routed through a stainless connection thread that accepts a 1/4 inch fitting. This closed circuit removes stator heat and allows the motor to sustain rated output without external airflow. The measuring device is a single-turn absolute encoder that uses an EnDat2.1 interface delivering 2048 increments per revolution and supplied from 7-12 V, so drive electronics receive position data immediately after startup. The enclosure meets IP65, blocking dust ingress and low-pressure water jets. Electrical energy is fed through a round connector located on the B-side of the stator, simplifying cable routing inside compact machine frames. The unit is supplied without a holding brake for installations where the drive itself holds the load stationary.
A high-speed bearing set supports the rated speed of 2500 rpm while keeping vibration within class C limits. The stator attaches to machinery through flange mounting that corresponds to frame size 100 and length B, which supports direct installation on compatible machine surfaces. Torque is transferred by a plain shaft delivered without a shaft-sealing ring, so external sealing must be arranged when connecting to oil-filled gearboxes. Insulation class F withstands winding temperatures to 155 °C, and the motor operates in ambient conditions from 0 to 40 °C. This operating range suits typical indoor production environments with controlled ambient conditions.
