Product Description:

The MAC112C-0-ED-4-C/130-A-1/W1520LX/S05 is an AC servo motor manufactured by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. It is intended for analog drive systems where rapid torque response and accurate velocity regulation are required in industrial automation lines. In automated machinery, it is often used on positioning and speed-controlled axes where stable response is needed during repeated starts, stops, and load changes. The unit receives current from a compatible servo amplifier, converts it into mechanical rotation, and reports speed back through its built-in tachogenerator or an optional absolute encoder so the controller can close the loop precisely.

Cooling is done via natural convection, so heat dissipates through the housing without forced airflow and requires unobstructed ambient circulation. This cooling method keeps the motor body free of added fan hardware, but surrounding air must circulate freely for consistent heat removal. With winding code ED, the stator resistance and inductance are matched to analog drives that supply the current bandwidth needed for dynamic applications. The motor reaches a nominal speed of 3000 rpm, allowing fast indexing while staying within the magnetic limits of the MAC112 frame. A centering diameter of 130 mm aligns the flange on machine mounts, and the integrated blocking brake provides 45 Nm of static torque for load holding during shutdown.

The motor has a frame size of 112 mm and a length code of C, which suit medium-range axes. Power conductors attach through a connector on side A, orienting the cable run toward the drive cabinet and helping avoid interference with adjacent modules. This cable direction can simplify routing when the motor is installed close to neighboring components or cabinet walls. The tachogenerator outputs 3 V/1000 rpm, which the controller uses as a linear speed feedback signal. An incremental or absolute encoder can be fitted in the same feedback channel, allowing either pulse counting or absolute position data without changing the mechanical package.
