Product Description:

The MAC112C-0-ED-4-C/130-B-0/WI520LV/S005 belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is a motor for analog drives that converts ±10 V command references into controlled torque and speed for positioning tables, feed axes, and spindle duties in automated machinery. Within production lines, it pairs with legacy MAC drive controllers to provide repeatable motion without digital network interfaces. This operating style makes it suitable for equipment that uses established analog control architecture and needs stable servo response during routine motion tasks.

The motor operates at a nominal speed of 3000 rpm, matching common inverter outputs used in analog velocity loops. Cooling relies on natural convection, so rated performance is maintained without external blowers or liquid circuits. A built-in tacho generator produces 3 V/1000 rpm, and the linear voltage allows the drive to calculate actual speed directly. Rotor position is reported by an incremental encoder mounted on the shaft, which supports accurate feedback for closed-loop control during changing load conditions. Electromagnetic loading follows the ED winding code, balancing current demand with torque at the design speed. The motor is supplied without a holding brake, which reduces residual drag on axes that must free-wheel when power is removed. Standard tacho quality is provided for general-purpose motion accuracy in conventional servo applications.

A centering diameter of 130 mm aligns the housing to gearboxes or flanges, and the shaft uses a DIN 6885 keyway for torque transfer through standard hubs. The motor uses motor size 112 and motor length C, a combination that balances inertia with continuous output for medium-duty axis arrangements. Power conductors exit through a connector on side B, which keeps the opposite end clear for coupling hardware or feedback cable routing. The feedback arrangement supports tacho feedback with encoder-based position reporting, so the motor fits control layouts that rely on separate speed and position signals.
