Product Description:

The MAC063A-0-ES-3-C/095-A-0 is a brushless AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it generates controlled torque and speed for position or velocity loops in industrial automation. The motor supports closed-loop motion tasks that require rapid acceleration, repeatability, and a compact footprint. These capabilities make it suitable for pick-and-place units, machine tools, packaging axes, and other automated equipment that relies on accurate rotary motion.

The motor uses winding code ES, which is optimized for the drive voltages used by compatible analog control cards. Under rated load, the rotor reaches a nominal speed of 3500 rpm, which must be considered when selecting couplings and transmission components. Cooling relies on natural convection, so heat passes through the aluminum housing without fans or forced airflow. The mounting flange has a centering diameter of 95 mm, allowing accurate alignment with gearboxes, belt pulleys, or machine mounting surfaces. The motor has no blocking brake, so a downstream mechanical device or active drive torque must hold the load when the axis is stationary. Its size 063 designation and motor length A provide a short housing that helps minimize mass and rotational inertia.

The feedback package combines tacho feedback with a second shaft end, allowing the drive to receive an analog speed signal while the additional shaft supports an external encoder or mechanical attachment. The tachogenerator delivers 1.5 V/1000 rpm, providing the control electronics with a linear voltage that can be scaled easily in analog circuitry. Feedback performance follows the manufacturer’s standard tacho quality, which is suitable for common positioning and speed-control applications without additional calibration. Power and signal conductors exit through a connector on side A, simplifying cable routing when the opposite side of the housing must remain clear. This connector position also helps accommodate installations in narrow machine spaces where cable bend clearance is limited.
