Product Description:

The MAC063A-0-RS-3-C/095-A-0 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it interfaces with legacy drive amplifiers that process voltage and tachometer signals instead of digital fieldbus data. Within automated equipment, it delivers programmable rotary motion for indexing tables, pick-and-place axes, and light spindle applications where accurate speed and torque regulation are required, and it works well in machines that continue to use established analog control architecture.

Its frame size is 063, and the A length keeps the overall mass low for faster acceleration. A 95 mm centering diameter aligns the flange to standard gearboxes for repeatable concentricity. Cooling relies on natural convection, removing heat without fans or liquid circuits and allowing cabinet integration with minimal airflow planning; this also reduces maintenance because no auxiliary cooling components are required. The motor reaches a nominal speed of 6000 rpm, and the RS winding sets the phase resistance and inductance to match the intended DC bus voltage of the analog controller. The built-in tachometer provides a stable velocity signal across the operating range, which helps the amplifier correct speed changes caused by shifting load conditions.

For installations that use external clamping devices, the unit is supplied without a blocking brake, leaving the shaft free when power is removed. Motion verification and auxiliary coupling are supported by tachometer feedback and a second shaft end, which permits simultaneous speed measurement and mechanical linkage to an encoder or load element; this arrangement also supports applications that need external feedback accessories. The tachometer generator outputs 1.5 V/1000 rpm, a level that analog drive cards interpret directly as a proportional velocity reference. Power conductors exit through a connector on side A, concentrating service points on one face of the machine and simplifying cable routing in control cabinets. This cable orientation can help keep harness runs organized in compact machine layouts.
