Product Description:

The MAC063C-0-MS-4-C/095-B-1/WJ520LX 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 converts drive commands into precise rotary motion for positioning and speed-controlled axes in industrial automation. The model incorporates a standard blocking brake for passive holding, which is useful when the axis must remain in place after power is removed. Its compact format also suits machine sections where installation space is limited but repeatable motion is still required.

The motor has a frame code of 063 and a centering diameter of 95 mm, so it mates directly with compact gearboxes or machine frames that share this pilot dimension. Rated speed reaches 3500 rpm, allowing rapid cycle times when paired with properly sized mechanics. During a power-off event, the integral brake can resist up to 3 Nm of static torque, preventing unintended shaft rotation. Heat generated by copper losses is dissipated through natural convection, so no external blower or liquid circuit is required. The C length gives the motor a moderate active stack height, which helps balance inertia and acceleration in compact axis layouts.

A right-angle power connector is located on side B, listed as a connector on side B, which helps keep the cable harness clear of adjacent components. The tacho generator outputs 1.5 V/1000 rpm, giving analog speed feedback for legacy controllers. The encoder option supports closed-loop positioning through incremental or absolute encoder feedback, which allows the drive to monitor shaft position during operation. Winding code MS indicates the electrical winding used for this motor, so compatible analog amplifiers can supply rated current without saturation. This arrangement supports stable speed regulation and straightforward cable routing in compact machine assemblies.
