Product Description:

The MAC063A-0-ES-4-C/095-B-1/AM144SG/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it supplies controlled torque and speed to positioning axes and continuous-duty actuators in industrial automation cells. This model combines a compact 63 mm frame with rotor and stator components tuned for precise motion control. It is intended for machine functions that need accurate starts, stops, and stable speed regulation over repeated cycles.

At its nominal operating speed of 3500 rpm, the motor delivers repeatable velocity while remaining within the thermal range supported by natural convection cooling. A standard blocking brake rated at 3 Nm secures the shaft whenever supply power is removed. That arrangement helps prevent unwanted shaft movement during idle periods or loss of power. The motor uses a 95 mm centering diameter to align the housing with gearboxes or machine plates, and torque is transmitted through a DIN 6885 keyway cut into the output shaft. Frame size 063 and motor length code A keep the overall dimensions short for installation in confined enclosures. The brake construction, winding insulation, and tacho quality are standard.

Electrical integration is simplified by a connector on side B that concentrates power conductors on the rear face of the stator. Rotor position is reported by an absolute encoder, and velocity feedback is also available as a tacho signal that produces 1.5 V/1000 rpm. This feedback arrangement supports closed-loop operation with absolute position data and analog speed information. By combining position and speed signals in the motor, the design reduces the need for separate external feedback devices. The motor uses winding code ES, which indicates the resistance and inductance values expected by compatible drive modules.
