Product Description:

Bosch Rexroth Indramat manufactures the MAC071C-0-GS-4-C/095-B-0/WI520LV/S005 within its MAC AC Servo Motors series. The unit is an AC servo motor used with analog drive amplifiers to deliver tightly regulated speed and position in industrial automation cells such as pick-and-place gantries or indexing tables. It converts electrical commands from the drive into mechanical rotation while encoder and tacho signals return real-time motion data to the control loop. This arrangement lets the external controller correct speed deviations quickly during acceleration, deceleration, and steady-state operation.

Winding code GS indicates the copper fill and electrical resistance used for medium-torque, high-speed duty. Rated velocity reaches 6000 rpm, providing headroom for fast cycle requirements before field weakening is necessary. Heat generated during operation is removed by natural convection, so no external blower or liquid circuit is required. A centering diameter of 95 mm aligns the stator housing with precision mounting features and helps maintain accurate shaft positioning. For velocity feedback, the built-in tacho produces 1.5 V per 1000 rpm, giving the analog drive a linear signal for continuous speed monitoring.

The motor is supplied with no blocking brake, so stationary loads must be supported by the drive or by external hardware. Power enters through a connector on side B, which can simplify cable routing when surrounding machine space is limited. Rotor and stator dimensions follow the series size code of 071, giving a compact envelope that fits many 100 mm frame machine layouts. Position feedback is provided by an incremental encoder mounted in the standard location behind the shaft. The mechanical depth corresponds to motor length C, which keeps the housing consistent with similar models in the same frame family.
