Product Description:

The MAC090B-0-ND-3-C/110-A-0/WI516LV is an AC servo motor in the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is built as a rotary actuator that delivers precise speed and torque control for industrial automation tasks that rely on analog velocity or current loops. When coupled to a compatible drive, the unit converts electrical commands into mechanical motion for indexing tables, feed axes, and conveyor sections that must maintain commanded profiles under varying load conditions.

This motor seats against the machine frame with a centering diameter of 110 mm, a dimension that simplifies coaxial alignment with gearboxes or direct-drive mounts. Heat generated in the stator is removed by natural convection. No fan or liquid circuit is required, so enclosure space and maintenance demands are reduced. The power lead enters through a connector on side A, allowing cable routing to match cabinets situated on that side of the machine. Because the model is classified as a motor for analog drives, its electrical characteristics match amplifiers that supply proportional current rather than digital position commands. The shaft is delivered without a blocking brake, so any static holding torque must be provided by the drive or an external mechanical lock during power-off conditions.

Position and speed feedback are delivered through a package that combines tacho feedback and a second shaft end; the tacho supplies real-time velocity data, while the additional shaft end permits an auxiliary encoder or load-side sensor. Absolute position is not transmitted; instead, the motor carries an incremental encoder with standard mounting that outputs phase-shifted pulses for commutation and motion control. Pulse accuracy follows a standard tacho quality grade suitable for general-purpose servo loops. These sensing features allow the motor to work with servo amplifiers and motion controllers that expect analog tacho and incremental signals.
