Product Description:

The MAF100D-0250-FQ-M2-AH0-05-A1 is an asynchronous housing motor manufactured by Bosch Rexroth Indramat for the MAF IndraDyn Asynchronous Motors series. Classified as a liquid-cooled asynchronous housing motor, it supplies rotational power for machines that need continuous torque while keeping enclosure temperature low. Its flange interface lets the unit bolt directly to a gearbox or machine frame, making it suitable for tightly packed industrial automation layouts where water-based cooling is already available. The housing motor format also helps keep the drive package compact when installation space around the axis is limited.

The motor relies on liquid cooling circulated through a connection thread sized at 1/4 inch, and this fitting ties the stator jacket to an external chiller loop for more effective heat removal than airflow alone. The housing carries an IP65 protection rating, and flange mounting simplifies mechanical integration while the A-side fixed bearing supports axial loads from overhung couplings. Its rated speed is 2500 rpm, which suits many pump, spindle, and process-duty applications that run for long periods at stable speed. The plain shaft is supplied without a shaft-sealing ring, so coolant lines must remain isolated from the drive end and the surrounding machine interface should be kept clean. Power is routed through an A-side connector, and the frame size 100 with length code D uses winding code 0250. The motor also uses Class F insulation, vibration grade A, and compliance with DIN EN 60034-14.

Position data comes from a multi-turn absolute encoder with 2048 increments per turn over an EnDat2.1 serial link, and the feedback supply is 7-12 V. The absolute encoder lets the control system read position immediately after startup, which supports axes that must return to operation without a separate referencing move. Because the motor is delivered without a holding brake, vertical axes require an external holding method during shutdown. The permitted operating temperature range is 0 to 40 °C, and the cooling circuit helps the motor stay within that range during continuous operation.
