Product Description:

The MAC112D-0-ED-4-C/130/A-2/MR121/S013 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It serves analog drive systems by converting electrical power into precise rotary motion for closed-loop positioning and speed control in industrial automation equipment. Because it is intended for analog drives, the motor is suited to systems that rely on external control electronics for current command, speed regulation, and axis positioning. It is intended for machinery that needs stable velocity control as well as repeatable stopping accuracy.

Its integral brake supplies 60 Nm of holding torque, allowing the axis to remain fixed when drive power is removed. A centering flange diameter of 130 mm helps align the shaft with gearboxes or direct couplings and reduces mounting play during installation. Heat is dissipated through natural convection, so the housing sheds thermal energy without a forced-air system. Rotor position is reported through tachometer feedback with an incremental or absolute encoder, giving the analog controller the information needed for coordinated speed and position control. Under rated excitation, the motor reaches a nominal speed of 3000 rpm.

Power enters through a connector on side A, which can simplify cable routing when the motor is mounted close to a machine wall. Separating the connection point from the driven end can also help keep cable bends away from the coupling area. The stator uses winding code ED, matching the electrical characteristics expected by compatible analog drive electronics. The motor is built in size 112, providing the frame dimensions associated with this housing class. It also includes a heavy-duty blocking brake, which is suitable for applications that require repeated clamping action during stops or power-off holding. The D-length stator is part of this configuration and contributes to the motor’s output capability without requiring a larger frame.
