Product Description:

The MAC090A-0-RD-2-C/110-B-0 is a servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Within an analog velocity or position loop, the unit converts drive current into rotary motion that can be coordinated with other axes, making it useful for pick-and-place modules, packaging stations, or light machining centers. Its construction follows the frame 090 layout, so existing Indramat mounting patterns and couplings can still be used in legacy analog automation systems.

The motor’s centering pilot is machined to 110 mm, which aligns the stator housing with gearboxes or flanges and helps reduce radial runout. Cooling occurs by natural convection, so heat leaves the stator through the surface area of the aluminum body without forced airflow. Rotor position is reported through built-in tacho feedback, allowing analog drives to derive velocity signals directly from the motor shaft. For applications with gravity loads or vertical axes, the unit is supplied without a blocking brake, so an external holding device may be needed. This arrangement keeps the motor simple while preserving compatibility with established analog drive systems.

Power conductors reach the winding through a connector on side B, which helps keep cables clear of gear reducers that often sit on side A. Designed as a motor for analog drives, it interfaces directly with ±10 V command stages rather than newer field-oriented digital inverters. Speed feedback is delivered with standard tacho quality, which provides sufficient linearity for medium-precision motion. The mechanical envelope, shaft dimensions, and electrical pinout match other MAC variants, allowing mixed installations across different torque ratings without requiring changes to the surrounding machine layout.
