Product Description:

Bosch Rexroth Indramat manufactures the MAC063A-0-ES-4-C/095-B-1/WI520LV for the MAC AC Servo Motors series. The unit is a permanent-magnet synchronous motor supplied with analog drive packages where precise speed and torque regulation are required. It acts as the electromechanical interface between the drive amplifier and the mechanical load, translating controlled stator currents into rotary motion for industrial axes in assembly, packaging, and material-handling equipment. Its compact envelope allows close mounting inside machinery while maintaining the thermal performance needed for continuous operation.

At a nominal speed of 3500 rpm, the rotor can deliver dynamic motion without exceeding rated thermal limits. A blocking brake rated at 3 Nm holds the shaft when power is removed, preventing drift on vertical or high-inertia loads. Accurate mechanical alignment is simplified by a 95 mm centering diameter that mates with standard flange patterns. Heat produced in the stator is dissipated by natural convection, so no forced-air or liquid cooling circuits are required. Power conductors are routed through a connector on side B, leaving the opposite face free for feedback cabling and mechanical couplings.

The motor has a size code of 063 and a length code of A, which correspond to the stack height and magnetic path used for its continuous output. Winding designation ES matches the resistance and inductance to analog drives that supply the required current profile. Position data are produced by an internal incremental encoder that works with the drive’s tacho feedback option. The encoder also supplies a tachometer signal of 1.5 V/1000 rpm for velocity loops that require low ripple. Standard tacho quality simplifies velocity feedback calibration, and the unit fits analog control architectures without additional accessories beyond the required power and feedback connectors.
