Product Description:

The MAC063A-0-ES-3-C/095-A-1 is a servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems, it converts controlled current from a servo amplifier into rotation that positions machine elements inside automated equipment. The assembly follows length code A, providing a compact body that fits shallow mounting areas. A standard blocking brake is included to secure the shaft whenever the controller removes operating voltage.

Its mechanical design centers on a flange with a centering diameter of 95 mm, which aligns the motor precisely against the mounting face and keeps radial runout low. Under rated excitation, the rotor reaches a nominal speed of 3500 rpm; the associated analog regulator maintains this operating point for steady-state motion. The built-in tachogenerator delivers a feedback signal of 1.5 V/1000 rpm, giving the controller a directly proportional voltage for closing the speed loop. When the machine is idle, the integrated blocking brake holds up to 3 Nm of static torque to prevent axis drift. Winding code ES indicates the stator resistance and inductance used to match the motor with a compatible drive.

Thermal management relies on natural convection; heat moves from the housing to the ambient air without fans or liquid circuits, so the installation must leave sufficient clearance for airflow. Motion data are relayed through tacho feedback and a second shaft end, allowing electrical speed sensing and mechanical coupling to an external encoder when greater positional accuracy is required. Power conductors reach the winding through a connector on side A, simplifying cable routing along the machine frame. The compact frame designation of Size 063 helps keep inertia low for responsive acceleration in positioning equipment. Its small housing also supports installation in machinery where available axial and radial space is limited.
