Product Description:

The MAC112C-0-ED-4-C/130-A-0/WI520LV/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it serves as the electromechanical actuator in automated lines that need accurate speed and torque control. Tacho and encoder devices fitted at the rear supply real-time feedback so the companion drive can close the velocity or position loop in metal-cutting, packaging, or material-handling equipment.

This model uses a centering diameter of 130 mm to seat the housing concentrically in machine frames. Heat is dissipated through natural convection, removing the need for external blowers. The rotor achieves a nominal speed of 3000 rpm, aligning with motion sequences common to analog control cards. A shaft-mounted tacho generator outputs 3 V/1000 rpm for stable velocity feedback. Frame code 112 identifies the stator diameter, which supports the motor’s torque capacity while keeping inertia moderate. The feedback compartment accepts either incremental or absolute encoder heads, allowing either basic commutation support or higher-resolution positioning. Because a blocking brake is not present, the shaft can coast when power is removed, which suits axes that rely on external holding devices.

Power conductors exit through a connector on side A, clearing adjacent modules inside compact control cabinets. Mechanical coupling is handled by a DIN 6885 keyway machined into the output shaft, providing positive torque transfer to gears or pulleys. The medium motor length C stack works with the ED winding code to indicate the resistance and inductance values required by the analog amplifier. Position sensing is delivered by an incremental encoder mounted in the standard orientation, while an optional absolute encoder may be used without changing the housing. The motor has no internal brake, so any load that must remain fixed at standstill requires an external holding method.
