Product Description:

The MAC063A-0-RS-3-C-095-B-0-S007 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for analog drive controllers, the unit supplies controlled torque and speed to automated axes in assembly machines, material-handling tooling, and light machining spindles. By combining a permanent-magnet rotor with closed-loop tachometer feedback, it allows the drive to regulate current in real time and convert electrical commands into repeatable mechanical motion for mid-power applications.

Its flange incorporates a centering boss diameter of 95 mm, aligning the housing concentrically with gearheads or mounting plates to help minimize shaft runout. Heat generated in continuous duty is removed through natural convection, so no external blower or liquid circuit is required. The motor’s armature is wound to reach a nominal rotor speed of 6000 rpm at rated voltage, giving additional speed range for dynamic positioning. Internal tacho coils deliver a feedback signal of 1.5 V/1000 rpm, allowing the analog drive to sense velocity directly. Winding code RS identifies the motor’s electrical characteristics, including the phase resistance and inductance values used by the drive for current loop tuning.

The mechanical envelope corresponds to frame 063 with overall length A, making the motor suitable for compact multi-axis nests. Position and velocity information are available from the built-in tacho feedback and a second shaft end, so an external encoder can be added when tighter positional accuracy is required. Power conductors exit through a connector on side B, which simplifies cable routing when the motor is installed against a panel on side A. The motor does not include a blocking brake, so load holding during power-off must rely on external measures. Standard tacho quality supports consistent speed feedback across identical motors.
