Product Description:

Bosch Rexroth Indramat builds the MAC112C-0-HD-4-C/130-A-0/WI522LV in its MAC AC Servo Motors series. This model is supplied as a motor for analog drives that integrates into velocity and position loops of presses, gantries, and packaging equipment. By generating controlled torque directly from drive amplifier commands, it forms the mechanical output stage of many legacy automation platforms. Integrated feedback channels let the connected amplifier track motor motion and correct for load changes during normal operation. These machines often depend on responsive motor behavior during repeated starts, stops, and directional changes. The motor is supplied without a blocking brake, so static holding duties must be provided by external clamping devices or drive torque.

The mechanical interface starts with a centering shoulder of 130 mm, allowing the housing to locate precisely against a machine flange and maintain concentricity under load. Heat is removed only by natural convection, so airflow around the frame must remain unobstructed during continuous duty. The rotor is designed for a nominal speed of 2000 rpm, giving drive controllers a predictable operating point for torque and speed regulation. Inside the stator, the HD winding code identifies an electrical winding arrangement used with medium-voltage analog amplifiers while balancing copper loss. Frame size 112 places the motor in a mid-sized housing that suits axes needing solid continuous output without an oversized installation footprint.

Additional dimensional data include the length specification C, which extends the active stack to raise continuous torque without altering the mounting footprint. Mains conductors terminate at a plug located on side A, easing cable entry from common cabinet orientations and helping keep routing straightforward near the motor face. For velocity feedback, the tachogenerator produces 3 V/1000 rpm, a level compatible with standard regulator cards used alongside this series. Position loops can instead reference the incremental encoder with standard mounting, which supplies quadrature pulses for finer motion control than the tacho alone. This combination supports stable speed regulation and repeatable positioning in equipment that still relies on analog servo architecture.
