Product Description:

The MAC112C-1-HD-3-C/130-A-0/S005 is manufactured by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. As a motor for analog drives, it delivers rotary motion and closed-loop speed regulation to machine tools, printing lines, and other automated stations that rely on analog velocity and current commands. The model’s coded designation identifies its frame category, winding family, and mechanical options so that integrators can match it precisely with a compatible drive controller.

The axial fan mounted on this unit operates from a supply of AC 230 V and forces air along the housing fins to enhance heat transfer; this matches the specified cooling method of Axial Surface Cooling. With a nominal speed of 2000 min⁻¹, the rotor can track speed references over a wide load range while the tachogenerator feeds back a calibrated signal of 3 V/1000 min⁻¹ for analog regulation loops. Standard tacho accuracy is stated, and the second shaft end incorporated in the feedback configuration allows mounting of additional sensors or mechanical couplings. A centering register of 130 mm simplifies alignment on precision mounting faces, and motor length code C defines the active stack height necessary to achieve the rated torque density without enlarging the footprint.

An internal brake is Not Present, so static holding torque must be supplied by the drive or an external fixture when the machine is idle. Power conductors exit through a Connector to side A, permitting cable routing that keeps service loops clear of moving parts. The electromagnetic package is wound to the manufacturer’s HD specification, giving a thermal profile suited for continuous cyclic duty within the MAC family. Frame designation 112 indicates the flange dimensions shared across this size class, allowing the motor to interchange mechanically with other 112-frame devices in existing automation layouts.
