Product Description:

Bosch Rexroth Indramat’s MAC093A-0-WS-4-C/110-B-0/D511LV/S005 is part of the MAC AC Servo Motors series and is supplied for analog closed-loop drives used in industrial automation. The unit generates controlled rotary motion so that indexing tables, feeders, and material-handling axes can follow velocity or position commands precisely. By combining a permanent-magnet rotor with electronic commutation, the motor maintains stable torque across its rated range, allowing production equipment to reach set speeds quickly and hold them under fluctuating mechanical load.

The mechanical interface uses a centering diameter of 110 mm, which seats the stator precisely against a gearbox or mounting flange. Heat produced by copper losses is removed through natural convection, permitting installation in cabinets without forced airflow. During continuous duty, the shaft reaches a nominal speed of 2000 rpm, a value chosen to match the frequency range of analog velocity loops. Power enters through a connector on side B, keeping high-current cables away from encoder wiring on the opposite face. For velocity feedback, the integrated tacho delivers 3 V/1000 rpm, giving the drive a linear voltage reference that can be scaled directly into speed error calculations.

Because the motor is supplied without a blocking brake, axis holding torque must be provided by the drive or an external mechanical lock when power is removed. Frame designation 093 sets the stator diameter, while stack length A keeps overall mass moderate for gantry or delta robot joints. Electrical characteristics are set by winding code WS, allowing the servo to achieve rated current at common bus voltages used in MAC analog amplifiers. Rotor position is monitored by a sensor that provides incremental or absolute encoder output, enabling both velocity loops and precise homing routines in a single package.
