Product Description:

The MAC063A-0-ES-4-C/095-A-0/WI520LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is supplied as a motor for analog drives, allowing positioning or velocity loops to be executed in an external controller while the motor provides the mechanical output. Used in assembly stations and light machine tools, it supplies the rotary motion required for axis control without onboard drive electronics. Because drive electronics are not integrated into the housing, current control and motion regulation are handled by the connected amplifier while the motor delivers torque at the shaft.

This unit follows size code 063, so its stator and flange dimensions suit compact machinery layouts. A centering diameter of 95 mm aligns the housing precisely on servo gearboxes or mounting plates, which helps minimize radial runout during operation. Heat is removed by natural convection, so ambient airflow cools the motor without an external fan. The motor reaches a rated speed of 3500 rpm, which suits medium-inertia tooling and rapid index cycles. Winding code ES identifies the electrical winding used in this motor, and the A motor length gives a shorter magnetic stack that reduces mass and inertia for faster acceleration. This shorter body can also help where installation depth is limited.

The motor has no blocking brake, so holding torque must be provided by the drive or by external mechanics when power is removed. Three-phase power is routed through a connector on side A, which simplifies cable exit on machines where the drive cabinet is positioned on that face. Rotor position is monitored by an incremental encoder mounted in the standard interface. A tachogenerator delivers 1.5 V/1000 rpm for speed feedback, and the standard tacho quality supports analog velocity loops without extra calibration. The encoder signal supplies position information to the controller, while the tacho signal provides a direct speed reference for analog regulation.
