Product Description:

The MAC112C-0-HD-3-C/130-A-0 W is manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is a brushless actuator that pairs with analog servo drives to deliver closed-loop speed and position control in industrial automation. By translating current commands into rotary motion, the motor supports feed axes, transfer stations, and process lines. Its design combines permanent-magnet excitation with an internal tachogenerator, supplying real-time velocity feedback so separate encoder channels are not always necessary on legacy installations.

A centering pilot of 130 mm aligns the housing to gearboxes or machine plates, while frame code 112 indicates the stator diameter used by this motor. The length index C denotes the third housing depth available in this series and provides additional active copper for higher continuous torque. The shaft reaches a nominal speed of 2000 rpm, which serves as the reference point for rating torque and tacho voltage. Heat is removed by natural convection, so unobstructed airflow around the ribbed housing is required and no external blower is fitted. The motor is supplied without a blocking brake, reducing mass when static holding torque is not needed.

Power conductors are routed through a connector on side A. The feedback package includes tachofeedback and a second shaft end, permitting direct voltage feedback while leaving the auxiliary shaft available for an additional encoder or mechanical coupling. At rated speed, the tachogenerator outputs 3 V/1000 rpm, a signal magnitude matched to Indramat analog velocity loops, and its tacho quality is standard for general-purpose accuracy. The winding set uses the HD winding code, which fixes resistance and inductance values so compatible drive modules can be selected without additional scaling.
