Product Description:

The MAC112D-2-ED-4-C/130-A-0/WI520LX/S05 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a motor for analog drives, it converts electrical commands from legacy or standalone amplifiers into precise rotary motion for automated tooling, conveying, and assembly equipment. Its integrated tacho feedback, optional encoder interface, and forced cooling help the unit maintain speed accuracy while delivering continuous torque in demanding industrial duty cycles. The motor is intended for positioning and speed-controlled applications that require stable response over extended operating periods.

The winding set identified by the ED winding code sets the phase resistance and inductance that let the drive reach a nominal speed of 3000 rpm without saturation. A 130 mm centering diameter aligns the flange with gearboxes or machine frames and simplifies concentric coupling during installation. Cooling is provided by axial surface cooling, and the external blower runs on a dedicated 115 V blower supply so the housing remains below permissible temperatures even at continuous stall torque. Forced airflow also supports low-speed operation where self-cooling would be less effective. The D-length housing provides room for the bearing arrangement while keeping inertia suitable for responsive speed control.

The MAC housing follows motor size 112, giving a shaft height and bolt circle that match standard Indramat gearheads. The motor has no blocking brake, so stopping torque must be supplied by the drive or an external mechanical latch. Power conductors enter through a side A power connector, making cable routing predictable in multi-axis cabinets. This cable exit arrangement is useful when several axes are mounted close together and wiring paths must remain consistent. Speed feedback is generated by the internal tacho generator, which produces a 3 V/1000 rpm tacho output rated for standard quality. An incremental encoder with standard mounting can be added when position capture is required.
