Product Description:

The MAC112D-1-PD-4-C/130-B-1/AM164SG/S005 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for analog drive systems, the unit converts electrical command signals into controlled rotary motion for positioning or velocity loops in automated machinery. Its construction follows a modular frame concept, allowing the motor to integrate with compatible power stages, feedback devices, and cooling accessories while preserving a standardized mechanical interface used on motion axes that require precise closed-loop control and consistent mounting geometry. It is suited for machine axes where accurate response, repeatable mounting, and compatibility with analog feedback hardware are important.

This size 112 motor with D length uses an internal blocking brake rated at 45 Nm to secure the shaft during power-off conditions. Thermal management relies on a blower that operates from AC 230 V, pushing air across the housing fins to support axial surface cooling during continuous operation. Under rated electrical excitation, the rotor reaches a nominal speed of 1500 rpm, which suits constant-torque duty with compatible analog amplifiers. For concentric alignment during flange mounting, the motor uses a centering pilot of 130 mm, which fits standard machine faces and helps maintain runout accuracy. The power conductors exit on side B through a sealed connector to keep cabling separate from encoder lines.

Torque is transferred through a DIN 6885 keyway, which locks the load to the shaft without slippage. Speed feedback is delivered by a tacho generator that produces 3 V/1000 rpm, and position data is supplied by an absolute encoder. This arrangement gives the drive separate channels for velocity and position information during operation. Winding code PD, together with the blower arrangement and position sensors, supports stable response in analog control loops without requiring an external cooling unit.
