Product Description:

The MAC112C-0-HD-1-B/130-A-1-I01250/S05 is produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts current-controlled commands from a drive module into rotary motion for automated presses, pick-and-place actuators, and material-handling axes. The frame, rotor, and feedback sensor work together to support closed-loop positioning and stable speed regulation in industrial automation cells. Because it is intended for analog drives, the motor relies on external current regulation while returning motion information through integrated feedback channels. That combination supports accurate movement in machines that must maintain repeatable cycle timing under changing load conditions.

This model is supplied with a blocking brake that can hold up to 45 Nm of static load, allowing vertical or suspended axes to remain stationary when power is removed. A centering pilot of 130 mm aligns the flange to mating machine parts and helps keep runout low during operation. Heat is removed through natural convection, eliminating the need for forced air or liquid circuits. The motor transmits rotor position through incremental encoder feedback, enabling the analog controller to correct velocity and position errors in real time. The HD winding code indicates the phase resistance and inductance, so the associated drive can supply the appropriate current waveform without saturation. This arrangement is useful on axes that pause between moves or must resist gravity when the drive is disabled.

The assembly uses the C length class and a 112 stator frame, which provides a balance between continuous torque output and installed depth. The shaft can reach a nominal speed of 2000 rpm, matching common gear ratios used in indexing tables and belt drives. For velocity monitoring independent of the encoder, the integral tacho generator outputs 3 V/1000 rpm. Power and brake conductors exit through a molded connector on side A, which helps keep cable routing direct when the motor is mounted against machine plates or inside protective enclosures. The separate tacho signal gives the controller a dedicated speed reference, while the encoder supports position tracking during motion. Placing the power and brake connection on one side also helps keep harness routing orderly in compact machine spaces.
