Product Description:

Bosch Rexroth Indramat manufactures the MAC112D-2-ED-4-C/130-A-0/WI520LV/S005 as part of the MAC AC Servo Motors series. The unit is a motor for analog drives and serves as an electromechanical actuator in closed-loop industrial automation, where it converts commanded current into precise rotary motion for positioning tables, feeders, and packaging spindles. By working directly with legacy analog amplifiers, it supports established control platforms that still depend on conventional velocity and position feedback rather than newer digital communication methods.

The motor uses a 130 mm centering diameter that matches common machine flanges, and motor length D provides the stator stack depth used for this torque class. Heat is removed by axial surface cooling, and the external blower operates on AC 115 V so cooling air is supplied independently of the main cabinet ventilation. Under rated excitation, the rotor reaches 3000 rpm, making the motor suitable for mid-range cutting, indexing, and other applications that need stable speed with repeatable response. The ED winding is arranged for analog current-loop operation, and the motor is supplied without a blocking brake so the shaft can turn freely when power is removed.

The output shaft includes a DIN 6885 keyway, allowing pulleys or gear wheels to be mounted without custom broaching. Power connections use a connector on side A, which helps separate high-current cabling from the feedback path and can simplify routing in compact machine layouts. Position data come from an incremental encoder with standard mounting, while the built-in tacho generator supplies 3 V/1000 rpm for analog velocity control. The feedback arrangement can be used for tachofeedback, incremental feedback, or absolute encoder operation, which helps the motor fit existing axis hardware that was designed around classic analog command structures.
