Product Description:

The MAC112B-0-GG-4-F/130 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drive systems, the unit converts drive commands into controlled torque and position, allowing automated machinery to move with repeatable accuracy in packaging lines, handling gantries, and general motion axes. By integrating rotor magnets with matched stator windings, it delivers closed-loop performance that works well with legacy proportional controllers. Its housing follows the established series footprint, which supports installation in existing machine layouts.

The flange offers a centering diameter of 130 mm, ensuring concentric alignment between the motor housing and adjacent gearboxes. Frame size code 112 identifies the motor’s stack diameter and corresponding magnetic cross-section. Heat is released to ambient air through natural convection, so no external blower or coolant circuit is required. The rotor reaches a nominal speed of 3000 rpm, giving the drive a standard operating speed for motion control. For velocity feedback, the tachogenerator delivers 3 V/1000 rpm, giving the amplifier a proportional signal that scales linearly with shaft speed. Tight tolerances on the centering surface help reduce radial runout during operation.

Electrical behavior is indicated by winding code GG, which corresponds to the resistance and inductance values used for this motor configuration. The stack depth identified as length B keeps inertia low while still supporting the continuous torque expected from the 112 frame. For position monitoring, the motor can use tachofeedback with an incremental or absolute encoder, allowing either pulse counting or absolute position data to reach the controller. The tachogenerator is configured for increased smooth run quality, which helps reduce velocity ripple when the load changes. This combination supports stable speed control in analog drive applications where consistent feedback is important.
