Product Description:

The MAC112C-0-HD-2-C/130-B-1 is an AC servo motor built by Bosch Rexroth Indramat for inclusion in the MAC AC Servo Motors series. Designed as a motor for analog drives, it converts drive controller commands into precise shaft movement for positioning tasks on machine tools, printing lines, or material-handling axes, allowing accurate speed-controlled and positioning motion in equipment that depends on stable analog command processing. The motor includes a factory-installed blocking brake so the shaft can be held when the drive is de-energized.

The rotor is aligned in the machine housing by a 130 mm centering diameter, giving a rigid radial seat that helps keep the coupling gap consistent during operation. Rated speed reaches 2000 rpm, matching drive systems that supply sinusoidal output at moderate frequencies for mid-range dynamic response during acceleration, steady running, and controlled deceleration. Heat is carried away solely by natural convection, so continuous torque must be considered with ambient temperature in mind. Frame size code 112 indicates the stator outer dimensions and bolt pattern, while winding code HD indicates the copper fill and turns ratio required to meet the motor’s voltage and current limits in this frame. Motor length C provides the active stack height that balances inertia against continuous torque capability for this housing size.

Holding performance during shutdown is delivered by a blocking brake supplying 45 Nm of static torque. For speed feedback, a tacho generator outputs 3 V/1000 rpm, supplying analog velocity information to legacy drive cards. This signal supports analog control loops that regulate shaft velocity directly from motor-generated feedback. Power conductors are routed through a connector mounted on side B, simplifying cable runs in line-built machines that service motors from the rear of the axis. Closed-loop velocity regulation is accomplished with integrated tacho feedback, which eliminates the need for an external encoder when only speed, not absolute position, must be controlled.
