Product Description:

The MAC063A-0-RS-4-C/095-A-0 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It functions as a motor for analog drives, turning proportional command signals into controlled rotary motion for positioning tables, pick-and-place units, and light feed axes in industrial automation. Its electrical and mechanical interfaces follow established analog controller layouts, which helps it fit existing machine platforms without changing the basic drive concept.

At the mounting face, the motor provides a centering diameter of 95 mm, which helps align it concentrically to gearboxes or machine plates. The frame designation 063 identifies the stator diameter and supports low rotor inertia for rapid duty cycles. Heat leaves the housing through natural convection, so no external blower or coolant circuit is required. When supplied with rated excitation, the shaft reaches 6000 rpm, which suits compact spindle and feed applications. Power and feedback conductors exit through a connector on side A, helping keep cable runs inside guarding when the motor is flange mounted. Length code A is the shortest stack available in this size, which keeps the motor compact while maintaining useful continuous torque.

Mechanical holding force must be supplied by the drive because the motor has no blocking brake, which reduces mass when power-off load retention is not required. Velocity feedback can be taken from a tachogenerator paired with an incremental or absolute encoder, allowing either simple speed control or more precise position regulation. The tachogenerator outputs 1.5 V/1000 rpm, supplying the analog controller with a scalable reference signal. The stator uses winding code RS, which corresponds to electrical values matched to the drive's parameter tables. Standard tacho quality supports stable speed feedback across the operating range.
