Product Description:

The MAC112D-0-ED-4-C/130-A-0/WI520/S05 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a motor for analog drives, it converts commanded current into precise torque for positioning tables, tooling spindles, and material-handling axes in industrial automation. The unit interfaces with Indramat drive amplifiers that close the velocity and position loops externally, allowing machine builders to obtain consistent motion control without integrating complex electronics into the motor housing.

A centering pilot with a diameter of 130 mm simplifies alignment with gearboxes and mountings, maintaining concentricity between the shaft and the driven load. Heat produced by the stator is removed through natural convection, so no blower or liquid circuit is required and cabinet airflow remains unaffected. The motor has a frame size of 112, providing a balance between continuous torque output and installation footprint. Under rated excitation, the rotor reaches a nominal speed of 3000 rpm, which matches the base frequency limits of the paired analog amplifiers. Power conductors exit through a connector located on side A, which directs cable routing toward that face of the machine and keeps the opposite side clear for feedback devices.

The stack depth identified by length code D increases the magnetic path, raising continuous torque without altering the mounting pattern. Rotor velocity is monitored by a tacho generator that delivers 3 V/1000 rpm, supplying an analog signal to the external controller for speed regulation. The stator uses winding code ED, which establishes the voltage constant and current draw expected at nominal load. The motor is supplied without a blocking brake, so any static holding force must be provided by external clamping or the drive’s torque-holding capability.
