Product Description:

Bosch Rexroth Indramat builds the MAC AC Servo Motors series for analog drive systems. The MAC112D-0-ED-4-C/130-A-2/WI520LX/S013 serves as an AC servo actuator for closed-loop axes in industrial automation. It converts commanded current from an analog drive into mechanical rotation, supplying precise speed and torque for packaging lines, machine tools, and material-handling equipment. The housing combines braking, cooling, and feedback functions in one assembly, so the motor can be mounted as a single unit on synchronized multi-axis platforms. It is intended for applications that require repeatable response during coordinated multi-axis motion.

The motor includes a heavy-duty blocking brake that provides up to 60 Nm of holding torque when the axis is stopped or power is removed. A 130 mm centering flange helps align the shaft with connected gearboxes and keeps runout low at elevated speed. Cooling is done by natural convection, so the frame requires unobstructed airflow rather than forced cooling hardware. Length code D extends the active stack to increase continuous power without changing the outer diameter. Under rated excitation, the rotor reaches 3000 rpm, which suits spindle and feeder applications. Its winding data are matched to compatible analog amplifiers so nominal current can be supplied without derating.

For installation, the power conductors exit through a connector on side A, which supports orderly cable routing inside the machine. The motor uses size 112, matching the MAC mechanical format for 112-frame mounting patterns. Position feedback is supplied by an incremental encoder with standard mounting and integrated tachofeedback for analog control loops. The tachogenerator outputs 3 V/1000 rpm, giving the drive a direct speed-related signal during operation. The standard tachofeedback quality supports stable speed regulation across the commanded operating range. The encoder and tacho signals support velocity and position control without external sensors.
