Product Description:

The MAC112C-0-HD-4-C/130-B-0/WI524LV/S005 belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is an AC servo motor intended for use with analog drive amplifiers, where it delivers commanded torque and speed to automated axes. By combining a compact stator design with servo-oriented windings, the motor converts electrical input into controlled mechanical rotation for positioning tables, transfer lines, and other motion tasks in industrial automation systems. Its layout also supports stable response during repeated starts, stops, and speed changes in continuously operated machinery.

Cooling is handled by natural convection, so installation must allow unobstructed airflow around the housing. The unit reaches a nominal speed of 2000 rpm, providing stable velocity for continuous duty without external fans. A centering diameter of 130 mm assists precise flange alignment with gearboxes or machine frames. Speed feedback is provided by an internal tacho generator that yields 3 V/1000 rpm, allowing the connected amplifier to monitor motor speed during operation. Winding code HD identifies the electromagnetic setup used for this version and corresponds to the torque constant and current rating expected by the matching drive. The motor is supplied without a blocking brake, so holding torque must be provided externally when power is removed.

The motor uses size code 112, and the shaft is machined with a DIN 6885 keyway for positive torque transmission to couplings or pulleys. Its overall stack height corresponds to length code C, offering a balance between torque output and inertia. Power conductors are terminated through a connector on side B, which can simplify cable routing in compact cabinets. An incremental encoder with standard mounting supplies position feedback to the drive, supporting controlled acceleration and repeatable axis movement. This arrangement suits analog servo systems that require separate speed and position signals for closed-loop operation.
