MAC112D-2-HD-4-C/130-B-1/DI520LV

The MAC112D-2-HD-4-C/130-B-1/DI520LV is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is designed for analog drives and can provide precise speed and torque regulation in industrial automation cells, material-handling axes, and processing equipment. Its feedback channels allow a compatible controller to compare commanded movement with actual rotor response, supporting accurate corrections when speed or load conditions change. The motor can therefore operate as part of a closed-loop motion system for positioning, controlled acceleration, and continuous rotation.

This model includes a standard blocking brake rated at 45 Nm, which holds the shaft when power is removed. An internal blower powered by an AC 115 V source forces air across the housing and supports the motor’s axial surface cooling system. Accurate alignment with the machine interface is aided by a 130 mm centering diameter. The rotor has a nominal speed of 1500 rpm for continuous motion tasks. The housing uses motor length D, providing the required active motor length for this configuration. Its HD winding code identifies the winding arrangement used with compatible analog drive modules. Position feedback is available in incremental or absolute form, allowing the controller and feedback configuration to be matched to the required motion accuracy.

The power leads exit through a connector on side B, simplifying cable routing when the drive equipment is located on the opposite side of the installation. A tachogenerator delivers 3 V per 1000 rpm so the analog controller can monitor motor speed without an additional external transducer. The tachometer has standard signal quality for velocity-loop operation. The incremental encoder uses shock-damped mounting to reduce the effects of machine vibration on the feedback assembly. The motor has a frame size of 112, which provides a compact installation profile while accommodating the internal components required for controlled industrial motion. Its electrical and feedback connections support real-time speed monitoring during changing load conditions.
