Product Description:

Bosch Rexroth Indramat manufactures the MAC112C-0-ED-4-C/130-A-0/WI520LX/S05, an AC servo motor in the MAC AC Servo Motors series. Designed for integration with analog velocity and torque amplifiers, the motor converts electrical commands into repeatable mechanical motion for positioning tasks in automated equipment. Its electromagnetic package, mechanical envelope, and sensor suite are tailored to rotary axes that require continuous duty at medium speed while maintaining direct feedback for the drive controller. Installation relies on a centering shoulder and connector architecture shared across the series for consistent mounting.

The motor has a rated mechanical speed of 3000 rpm, allowing stable operation with analog drive outputs at full load. A centering shoulder diameter of 130 mm seats the stator accurately against mounting plates to preserve alignment. Thermal control is provided by natural convection, eliminating auxiliary blowers and reducing wiring complexity. The ED winding code indicates the coil resistance and inductance expected by the amplifier. For velocity feedback, an internal tacho delivers 3 V/1000 rpm, and this proportional voltage signal supports speed loops. Length code C indicates the active stack size within the housing.

The motor has no blocking brake, so the axis must rely on dynamic motor torque or external locks when de-energized. The motor uses frame 112, which provides flange dimensions common to mid-range machinery. Power conductors exit through a connector on side A, which helps simplify cable routing inside the cabinet. Motion sensing uses an incremental encoder with standard mounting, and the feedback arrangement supports compatible controller inputs. The unit is intended for analog drives and works with legacy MAC amplifiers without additional interface modules.
