Product Description:

The MAC112D-2-ED-4-C/130-A-0/D1520LV/S005 belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is an AC servo motor intended for analog drives, where it provides closed-loop torque and speed control to positioning tables, handling modules, and other automated axes. By converting electrical command signals into precise mechanical rotation, the unit serves as a direct actuator in industrial motion systems.

The motor uses size code 112 and length code D, giving a frame that suits medium-duty feed axes while keeping inertia moderate. A centering diameter of 130 mm aligns the flange with gearboxes or machine frames. The rotor reaches a nominal speed of 3000 rpm, supporting rapid cycle times in pick-and-place or spindle duties. Thermal energy is removed by axial surface cooling, where airflow from an external blower moves along the housing ribs to help maintain continuous torque. Winding code ED indicates the copper fill and turns ratio used in the stator, and the motor does not include a blocking brake, so mechanical holding must be supplied externally. Power enters through a plug connector on side A, which can simplify cable routing in shallow cabinets.

The blower operates from an auxiliary supply of AC 115 V, so a standard control transformer can energize the fan circuit. Rotor position and velocity feedback are generated by a tacho assembly that delivers 3 V/1000 rpm and can be combined with an incremental or absolute encoder for higher-resolution control loops. Shaft torque is transmitted through a key cut to the DIN 6885 profile, which supports interchangeability with commercial couplings. Standard tacho quality and the analog drive interface make the motor suitable for retrofit applications where existing controllers rely on voltage-proportional speed signals while still requiring precise dynamic response.
