Product Description:

The MAC112C-2-ED-4-C/130-A-2/WI520LV/S018 is an AC servo motor from Bosch Rexroth Indramat in the MAC AC Servo Motors series and is intended for analog drives. It converts command signals from an external controller into controlled shaft rotation for printing, packaging, and material-handling equipment. Integrated electrical feedback lets the paired drive monitor motion continuously, which supports stable speed regulation and repeatable positioning during changing loads. The motor combines motion, holding, and cooling functions in one housing, which helps keep the axis layout compact. This arrangement is useful where consistent response is required through frequent starts, stops, and speed changes.

The motor includes a heavy-duty blocking brake with a holding torque of 60 Nm, so the shaft can remain locked after power is removed. This is useful on vertical or suspended loads where drift at standstill must be prevented between motion cycles. The winding supports a nominal speed of 3000 rpm, and cooling air is supplied by a blower operating on AC 115 V to carry heat away from the housing during continuous duty. A centering diameter of 130 mm helps align the motor accurately on the machine flange and keeps shaft positioning consistent during installation.

Cooling is provided by axial surface cooling, which directs airflow along the outer surface so heat can be removed from the stator area during operation. Winding code ED identifies the electrical configuration used for this motor, and motion feedback is supported by an incremental encoder with a standard-quality tachogenerator. The tachogenerator provides 3 V/1000 rpm to the analog control loop, giving the drive a proportional speed signal for regulation. Power is connected through a connector on side A, which keeps the cable exit on one face of the housing and can simplify routing where cabinet space is limited.
