Product Description:

The MAC112D-0-ED-3-C/130-A-1 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is built to interact with analog velocity and position controllers, translating ±10 V command signals into precise torque and speed that keep automated axes synchronized with process demands. By combining electromagnetic actuation with resolver-based commutation, the unit supplies continuous rotary power to packaging lines, transfer systems, and general motion platforms without the latency associated with pneumatic or hydraulic devices.

The integrated blocking brake delivers 45 Nm of holding torque, allowing vertical or overhung loads to remain stationary when drive power is removed. A centering diameter of 130 mm aligns the stator housing concentrically to mounting flanges so shaft runout stays within tolerance. Heat produced in the winding is removed by natural convection, eliminating external blowers and reducing maintenance points. The frame is categorized as Motor Size 112, and its rated operating speed is 3000 rpm. Winding code ED identifies the electrical winding arrangement so that current, back EMF, and impedance match the voltage range of legacy analog amplifiers, while the standard tacho quality supports routine velocity feedback accuracy.

Power to the stator is routed through a connector on side A, keeping cable runs short inside the control enclosure. Velocity feedback is generated by a sensor package with tacho feedback and a second shaft end, providing an independent signal path for redundancy or external speed monitors. The tachogenerator outputs 3 V/1000 rpm, a value recognized directly by most analog regulators. A stack length designated as Motor Length D extends the magnetic core to raise continuous power without altering the mounting footprint. The blocking brake is supplied as standard equipment, and the motor is intended for analog drives, which makes it suitable for retrofit projects that retain existing controller hardware.
