Product Description:
The MAF100B-0250-FR-S2-BH0-35-N1 is a liquid-cooled asynchronous housing motor produced by Bosch Rexroth Indramat within the MAF IndraDyn Asynchronous Motors series. Designed for integration with servo drives and pumps, the unit converts electrical energy into rotational motion for tasks that demand continuous torque and tight thermal management on the factory floor. The motor follows DIN EN 60034-14 vibration guidelines and fits applications that call for accurate feedback through its single-turn absolute encoder. Its housing design is suited to installations where heat must be carried away by coolant rather than by ambient airflow. This makes it suitable for compact equipment where stable temperature control is important during continuous operation.
It reaches a rated speed of 2500 rpm, and this operating point allows stable mechanical output when the drive delivers nominal current. Heat generated in the stator is removed by liquid cooling; coolant enters through an enclosed rapid-action coupling sized at 1/4 inch, so installation is quick and leak-tight. A protection rating of IP65 blocks dust and water jets from entering the housing, making cabinet-free mounting possible. Position data moves to the drive over the EnDat2.1 interface, and the feedback is quantized into 2048 increments, providing sufficient resolution for speed loop control. The encoder operates on 7–12 V, while power is routed through a B-side connector that matches the winding code 0250. The connector arrangement keeps power and feedback paths separated within the motor package. Standard bearings support the plain shaft, and the design omits a holding brake and a shaft sealing ring to reduce drag and simplify maintenance.
Thermal endurance is supported by insulation class F, allowing the windings to reach 155 °C without premature aging. Machine builders can secure the motor by flange and foot mounting, matching the 100-frame size and B-length to common gearboxes. During normal operation, vibration severity remains within class A, which helps limit transmitted vibration at the machine interface. Operation is specified for ambient air between 0 to 40 °C; outside this range, derating is required. This layout suits machines that already provide external load holding and centralized coolant routing.
