Product Description:

The MAC112B-0-PD-4-C/130-A-1 is an AC servo motor produced by Bosch Rexroth Indramat in the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts command voltages into precisely controlled motion for machine tools, packaging stations, and material-handling axes. When used in a closed-loop system, it supplies regulated torque and speed to keep industrial processes synchronized with controller commands. This makes it suitable for axes that need repeatable motion during indexing, feed control, or continuous speed regulation.

The motor has a frame size of 112, which gives it a stator diameter suited to medium-duty automation. A centering pilot of 130 mm aligns the housing accurately on gearboxes or mounting plates. This pilot helps seat the housing accurately against a machine face or gearbox input, which supports consistent shaft alignment during installation. Its nominal speed is 1500 rpm, which supports continuous operation at the rated operating point. Heat is removed by natural convection, so no auxiliary fan or liquid circuit is required. An integrated blocking brake provides 45 Nm of static torque to hold vertical or torque-loaded axes when power is removed. This brake is useful when the load must remain in place after drive power is removed.

Winding code PD indicates electrical values used by compatible analog drive buses. The three-phase supply reaches the stator through a connector on side A, which can simplify cable routing when the shaft faces a gearbox. Rotor position is monitored by tacho feedback, and the tacho produces 3 V/1000 rpm for the speed loop while maintaining the series' standard accuracy rating. That feedback gives the drive a stable speed signal for regulation during changing load conditions. The mechanical stack corresponds to length B, which gives the motor a predictable overall depth for couplings, pulleys, or belt drives in confined machine frames.
