Product Description:

The MAC112D-0-ED-1-B/130-B-0/I01250/S05 is a servo unit from the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. Delivered as a motor for analog drives, it converts current supplied by legacy velocity or torque controllers into controlled mechanical motion for pick-and-place stations, packaging lines, and general machinery. Its design supports applications that need closed-loop positioning and stable speed regulation through external drive control.

With a centering diameter of 130 mm, the housing seats directly into standard machine flanges, providing axial alignment without additional shims. Heat is removed through natural convection, a passive method that avoids external blowers and keeps the overall footprint small. Position data is sent back to the drive by incremental encoder feedback, enabling real-time velocity regulation based on line-driver signals. The mechanical build follows the D length code, which provides additional active stack height for higher continuous torque than shorter variants. A frame designation of 112 identifies the stator outer diameter group used across the MAC platform.

During operation, the rotor is intended to run at a nominal speed of 3000 rpm, matching the frequency range produced by most analog servo amplifiers in the Rexroth ecosystem. A power cable enters through a connector on side B, simplifying cabinet layouts that place drives on the opposite side of the machine. For velocity feedback, the integrated tacho generator outputs 3 V/1000 rpm, giving the controller a proportional voltage reference for speed loops when incremental signals are unavailable. The electromagnetic circuit follows winding code ED, so resistance and inductance values align with amplifiers rated for this coil set. Because no blocking brake is present, any holding duty must be provided by the drive’s current control or by an external mechanical latch.
