Product Description:

The MAC112D-0-ED-4-C/130-A-1/WI517LV is an AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. Designed for analog drives, it delivers closed-loop rotary motion for machinery axes, tool spindles, and transfer stations that rely on voltage or current commands rather than digital fieldbus control. The unit incorporates a blocking brake for mechanical holding when power is removed, and its mechanical interface follows the MAC family outline for straightforward installation on compatible equipment.

The motor’s nominal speed is 3000 rpm, meaning the rotor reaches this velocity under rated voltage and load while balancing torque production with high-speed capability for general automation tasks. A centering diameter of 130 mm aligns the stator housing precisely on the machine plate, which helps reduce angular misalignment and vibration. Heat is removed by natural convection, so this passive method eliminates fan noise and extra wiring but requires free airflow around the housing. The blocking brake can resist up to 45 Nm of static load, so vertical axes or suspended tooling remain in position during shutdowns. Electrical characteristics correspond to the ED winding code, which matches the coil resistance and inductance used by legacy analog amplifiers in the MAC series.

Power is fed through a connector on side A, keeping cable runs short when the cabinet is located on that side of the machine. The frame corresponds to motor size 112, which provides a moderate shaft height while accommodating larger shaft diameters than smaller MAC100 frames. A built-in tacho generator produces 3 V/1000 rpm, and this voltage is proportional to speed for the velocity loop in analog controllers. Position information comes from an incremental encoder with standard mounting, allowing higher-resolution feedback to be added without altering the housing.
