Product Description:

The MAC112D-0-HD-2/130-B-0/S005 is an AC servo motor produced by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. As a motor intended for analog velocity and position loops, it translates drive current into precise rotary motion for axes used in presses, printing equipment, and material-handling stations. The unit combines magnetic windings with an integrated tachogenerator so the associated drive can close the speed loop without additional sensors. That arrangement supports stable servo response on machinery that uses conventional analog control architecture.

The housing uses motor size 112, while the active core extends to motor length D, balancing torque output with moderate inertia. The winding code HD sets coil resistance and inductance so rated current produces the intended magnetic flux. Under these electrical conditions, the shaft reaches a nominal speed of 1500 rpm. Heat is removed by natural convection, so unobstructed airflow around the ribbed stator is important for sustained fanless operation. For real-time velocity feedback, the motor is supplied with tacho feedback, generating a proportional voltage that the analog amplifier uses to limit overshoot during rapid load changes.

Because it is a motor for analog drives, the control scheme expects a bipolar ±10 V reference rather than digital fieldbus signals. This arrangement suits legacy machine controls that rely on direct analog command input and continuous speed-loop correction through the paired amplifier. It can be integrated into existing motion systems that already use analog servo electronics and do not require network-based control. Older production equipment often uses this approach where predictable speed regulation and simple electrical interfacing are more important than digital communication features.
