Product Description:

The MAF100D-0250-FQ-S2-AP0-35-N1 belongs to the MAF IndraDyn Asynchronous Motors series produced by Bosch Rexroth Indramat. It is a liquid-cooled housing design for automated machinery that requires continuous torque while keeping the motor size compact. By transferring heat to an external coolant loop, the unit supports higher current density than air-cooled motors without pushing winding temperature beyond normal operating limits. Its asynchronous design also supports variable-frequency operation, so the motor can be used with modern inverters for controlled acceleration, steady-speed running, and regulated torque in production lines, gantry axes, and forming equipment.

The enclosure is rated at IP65, which helps protect the stator and encoder from dust and low-pressure water jets during washdown cycles. Internal heat is removed by liquid cooling, and the winding supports a nominal mechanical speed of 2500 rpm, giving the drive enough range for common industrial speed control. Rotor position feedback is supplied by a single-turn absolute encoder that communicates through EnDat2.1. Its optical disk provides 2048 increments per revolution, which supports smooth low-speed motion and stable velocity regulation, and the encoder is powered directly by the drive from a 7–12 V supply so no separate supply rail is needed.

The motor uses Class F insulation, and routine operation should remain within an ambient range of 0 to 40 °C. Coolant enters the housing through a 1/4 inch thread near the connector side, and the motor uses an A-side power connection to keep the main cabling on one face of the machine frame. Mechanical installation is supported by flange and foot mounting, a balanced shaft with a complete key, and a shaft sealing ring for oil-mist environments. Compliance with DIN EN 60034-14 and vibration level A supports smooth running during continuous operation.
