Product Description:

The MAC090C-0-KD-4-C/110-A-0/WI522LX is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it converts current-loop commands from a drive controller into controlled rotary motion for industrial handling, machining, and material-processing equipment. The design pairs a tachogenerator with optional encoder feedback so the control system can monitor both speed and position during continuous operation and dynamic indexing tasks.

The motor uses a centering diameter of 110 mm, which aligns the stator housing precisely on a machine frame. Heat produced by copper losses leaves the housing through natural convection, so no external blower or coolant manifold is required. Under rated excitation, the rotor turns at 1500 rpm, a speed that matches common gear ratios and helps keep audible noise low. Power conductors reach the stator windings through a connector on side A, which simplifies cable routing where multiple axes are installed in parallel. The KD winding sets the resistance, inductance, and back-EMF values expected by the analog drive during current and velocity tuning.

The motor is supplied without a blocking brake, so holding or stopping torque must be provided externally when the axis is at rest. Shaft speed feedback for the velocity loop comes from the built-in tachogenerator, which supplies 3 V/1000 rpm and has a standard quality rating for linear voltage output across the operating range. Position data can be derived from an incremental encoder mounted in the standard rear housing, while the cabling layout also supports an optional absolute encoder with the same tacho feedback configuration. These feedback signals allow the analog controller to trim velocity and support repeatable positioning without additional external transducers.
