Product Description:

The MAF100D-0250-FQ-S2-AH0-05-N3 asynchronous motor is produced by Bosch Rexroth Indramat within the MAF IndraDyn Asynchronous Motors series. It is a liquid-cooled housing motor intended for high-precision industrial automation where regulated torque and stable thermal behavior are required. By combining an internal coolant circuit with an absolute encoder interface, the unit supports closed-loop speed control for conveyors, spindles, and forming axes that run under continuous duty. This arrangement helps the motor maintain consistent operation in applications where heat buildup and speed accuracy must both be controlled.

Heat is removed by liquid cooling routed to a rear manifold with a 1/4 inch connection thread, so the installation can use standard coolant fittings. The sealed aluminum housing has an IP65 rating, which helps protect internal parts in dusty areas and in locations exposed to spray, while the rotor reaches a rated speed of 2500 rpm. Position feedback is provided by a EnDat2.1 single-turn absolute encoder with 2048 increments per revolution, and its 7 to 12 V supply is provided directly by the drive. Class F winding insulation supports continuous thermal load, vibration level B limits running vibration in accordance with DIN EN 60034-14, and standard bearings carry radial forces while the coolant circuit also helps stabilize bearing temperature.

Mechanical integration is provided through flange mounting, and the motor uses a plain shaft without a shaft sealing ring to reduce friction at the output. The motor does not include a holding brake, so braking torque must be supplied by the drive or by external mechanical equipment when the axis is stopped. An A-side power connector keeps the cable route away from the coolant lines, and frame size 100 with length code D corresponds to the motor stack used for this version. Continuous service is permitted in ambient temperatures from 0 to 40 °C, provided that coolant flow is maintained.
