Product Description:

Bosch Rexroth Indramat manufactures the MAC063A-0-RS-4-C/095-A-0/WI634LX within the MAC AC Servo Motors series. Classified as a motor for analog drives, it supplies regulated torque and speed to machinery that still relies on analog velocity and position loops instead of fieldbus communication. It is suited to light-to-medium duty automation such as pick-and-place modules or compact indexing tables. The unit integrates tacho and encoder devices so the drive controller can maintain consistent motion profiles when the load changes during operation. Because the feedback devices are built into the motor, the drive can respond quickly to speed changes without requiring separate external sensing hardware.

The motor reaches a nominal shaft speed of 6000 rpm, which gives the axis a wide operating range for short-cycle applications. Mechanical centering is provided by a 95 mm pilot diameter, which keeps the stator concentric with coupled mechanics and helps reduce runout at the mounting face. Thermal energy is removed through natural convection, so installation must allow unobstructed airflow around the housing because no fan or liquid circuit is present. For wiring, the three-phase supply exits through a connector on side A, which keeps power leads on the same face as neighboring axes in multi-motor cabinets. The unit is supplied without a blocking brake, so the load must be held by external clamping or drive torque when power is removed.

Compact construction is reflected by the frame designation 063, which supports dense machine layouts while keeping rotor inertia low. Electromagnetic parameters follow winding code RS, which sets the resistance and inductance values expected by MAC analog amplifiers. Speed feedback is generated by a tachogenerator that produces 1.5 V/1000 rpm, giving the control loop a linear voltage signal for velocity regulation. Position information comes from an incremental encoder mounted in the standard interface. This arrangement lets the controller separate speed regulation from position tracking during rapid starts, stops, and short indexing moves.
