Product Description:

The MAC112C-0-KD-2-C/180-A-1/S003 is a servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for analog drive systems, the unit converts electrical command signals into controlled rotary motion for precise positioning and speed regulation on automated machine axes, transfer stations, packaging lines, and material-forming cells. Because it is intended for analog drives, the motor works with external amplifiers that regulate torque and velocity through closed-loop control. Heat is removed through natural convection, so the motor can be installed without auxiliary blowers when ambient airflow is adequate.

Its centering diameter measures 180 mm, allowing rigid seating on precision mounting flanges and helping keep shaft runout within tight limits during continuous duty. At a nominal shaft speed of 1500 rpm, the electromagnetic package delivers rated torque while matching analog velocity loops. A standard blocking brake generates 45 Nm of holding torque to secure vertical or overhung loads whenever the drive is disabled. For streamlined wiring, the power leads exit through a connector on side A, keeping the connection path on the same face as adjacent cabinet hardware. This layout supports straightforward cable routing where installation space is limited around the motor body.

The electrical winding identified by code KD sets the motor’s phase resistance and inductance profile for use with legacy Indramat analog amplifiers. Its tacho generator is built to a standard quality grade and supplies feedback suited to common accuracy requirements. Integrated tacho feedback provides a speed signal of 3 V/1000 rpm, which the controller can interpret directly without separate scaling hardware. Frame size 112 indicates the outside diameter and bolt circle, while length designation C increases active iron for higher continuous torque than shorter variants. The longer active stack supports steady output during continuous operation and helps maintain consistent performance during prolonged machine cycles.
