Product Description:

The MAC112C-0-ED-4-C/130-A-2/WI520LV/S018 is an AC servo motor manufactured by Bosch Rexroth Indramat in the MAC AC Servo Motors series. Designed for analog drives, it translates command voltages from traditional drive controllers into controlled rotary motion for industrial automation tasks such as positioning tools or transporting materials between process stations. Integrated tacho and encoder options support both speed control and position control on axes that require repeatable motion. This arrangement suits equipment that uses separate drive electronics instead of fully integrated motor control.

Mechanically, the stator housing uses a 130 mm centering diameter, allowing direct fit to gearboxes or machine frames without alignment bushings. Thermal dissipation relies on natural convection, so unobstructed airflow around the frame is required to maintain acceptable winding temperature. A heavy-duty brake rated for 60 Nm locks the shaft during idle conditions or power loss to prevent the load from backdriving. The ED winding code sets the resistance, inductance, and torque constants expected by compatible MAC drive modules. Under rated excitation, the motor reaches 3000 rpm, providing a standard base speed for general automation duty.

Electrical connection is simplified by a connector on side A, so power cabling exits in the same direction as the feedback leads for compact routing. Velocity feedback is generated by an internal tacho that delivers 3 V per 1000 rpm, a signal level suited to conventional analog velocity loops. For position control, the unit carries an incremental encoder with standard mounting, allowing high-resolution counts to be processed by legacy controllers. The size 112 frame provides a larger magnetic cross-section to support the motor's torque and thermal demands.
