Product Description:

The MAC063A-0-RS-3-C/095-B-0 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is a motor for analog drives that supplies closed-loop torque and speed control to industrial positioning systems, pick-and-place axes, compact handling modules, and similar automation stations. By combining a permanent-magnet rotor with internal tacho feedback, the unit delivers consistent velocity information for analog servo amplifiers during real-time motion tasks. Its feedback arrangement helps the controller respond quickly to load changes without relying on separate external sensing hardware.

The stator uses winding code RS, which matches the resistance and inductance values expected by legacy drive electronics. At its nominal speed of 6000 rpm, the motor can sustain continuous operation without external cooling because heat is removed by natural convection. A centering diameter of 95 mm aligns the flange precisely on machine frames, while the tacho generator outputs 1.5 V/1000 rpm so the drive can monitor actual shaft velocity against command values. The winding, rotor length, and housing correspond to Motor Length A, which helps keep inertia low for rapid acceleration. Tacho quality is standard, which is suitable for general-purpose contouring and feed applications. The high base speed also suits applications that need fine velocity control over a wide operating range.

The motor uses size 063, giving it a compact envelope that fits narrow installation spaces. Power conductors enter through a connector on side B, allowing cable routing away from the driven shaft and from auxiliary feedback devices mounted on the opposite end. Velocity feedback is provided by a package that combines tacho feedback and a second shaft end, which supports retrofit applications that require an additional encoder. The design is supplied without a blocking brake, so holding torque must be furnished by the drive or external clamping devices. This layout is useful when the machine must keep cable exits clear of couplings, pulleys, or neighboring axis components.
