Product Description:

The MAC090B-0-JD-4-C/110-A-0/AM164SG/S001 is an AC servo motor produced by Bosch Rexroth Indramat and placed in the MAC AC Servo Motors series. It is intended for velocity and position loops handled by ±10 V controllers rather than fully digital bus interfaces. In automated machinery, this motor supplies responsive torque to coordinate axes such as loaders, presses, or tool changers that depend on precise shaft positioning. That makes it suitable for retrofit machinery where the control cabinet already uses analog reference signals instead of networked motion buses.

The motor has no blocking brake, so holding force must be supplied externally when the axis is stopped. Accurate mounting is assisted by a centering recess of 110 mm, allowing direct coupling to gearboxes or machine frames with consistent alignment. Heat is removed by natural convection, eliminating fans and keeping the housing simpler where unobstructed airflow is available. Power conductors enter through a connector on side A, which helps route the cable away from moving members on many machine layouts. Rotor position is returned to the drive by an integrated absolute encoder, so the control system can read position immediately after power-up without a homing cycle.

Additional feedback is available through tacho feedback for incremental speed regulation, and its signal has standard tacho quality suited to general motion profiles. Because the device is a motor for analog drives, its sinusoidal back-EMF, encoder resolution, and tachometer constants match amplifiers that use analog command signals in existing control cabinets. This arrangement supports stable speed control during continuous rotation and repeatable position correction when the axis changes direction. The feedback channels also help the amplifier correct minor load-related speed changes without relying on a separate external sensor.
