Product Description:

The MAC112-0-ED-4-C/130-A-0/WI520LV servo motor is produced by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. Designed for analog drives, it converts commanded current into precise rotary motion for positioning and velocity control in industrial automation. The motor is suitable for machine tools, printing equipment, packaging systems, and material-handling axes that require controlled acceleration and repeatable movement. Integrated tachometer feedback and an incremental encoder allow the connected controller to regulate speed and detect position changes in real time.

The rotor operates at a nominal shaft speed of 3000 rpm, providing a broad operating range for speed-controlled machinery. Position feedback comes from an incremental encoder that produces 1250 lines per revolution, allowing the analog controller to detect small angular changes. The encoder supports switching frequencies up to 300 kHz, preserving signal resolution during high-speed operation. Drive electronics supply the sensor with 150 mA at 5 V, and its TTL square-wave outputs provide reliable signal transmission in electrically noisy industrial environments. The encoder is mounted on the motor end bell, while the tachometer signal is routed internally so the control loop receives velocity and incremental position data. Power conductors exit on side A, allowing the cable path to be directed toward the corresponding machine wiring route.

Mechanical alignment is provided by a 130 mm centering register that positions the motor accurately against gearboxes or machine brackets. The housing has an IP65 protection rating, preventing dust ingress and resisting low-pressure water jets during washdown. Heat generated by the stator windings is removed through natural convection, so the installation does not require an external blower or coolant lines. During rotation, the built-in tachometer produces 3 V/1000 rpm, supplying proportional speed feedback to analog amplifiers that operate with voltage signals. The standard tachometer design allows the controller to monitor velocity independently of the incremental position channel. The sealed housing also protects internal feedback components from contamination while allowing heat to dissipate through the motor surface.
