MAC063D-0-FS-4-C/095-B-0/WI522LV/S023

The MAC063D-0-FS-4-C/095-B-0/WI522LV/S023 is an AC servo motor produced by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. Designed for analog drives, it converts current commands from a servo amplifier into accurate mechanical motion for positioning tables, small transfer axes, and packaging actuators. The unit incorporates incremental encoder and tachometer feedback so the control electronics can monitor both speed and position without external sensors, providing the closed-loop regulation required for repetitive industrial cycles.

The frame is coded 063, and the motor seats against a centering recess of 95 mm, allowing direct mounting to compact gearheads or flanges without shims. Winding code FS indicates the copper fill and coil pitch used to match the motor with drives that supply moderate current while favoring a higher base speed. The nominal speed is 6000 rpm, allowing routine processes to operate at high cycle rates before field weakening is needed. Thermal energy is removed by natural convection, so airflow around the housing must remain unobstructed to keep the windings below permissible temperature limits. This cooling method eliminates the need for a separate fan and reduces the number of auxiliary electrical connections required around the motor.

The length index D provides a deeper magnetic stack that raises torque without changing the frame cross section. Power enters through a connector on side B, simplifying cable routing in installations where the motor back face points toward a wall or machine enclosure. The motor has no blocking brake, so machines that require static holding torque must rely on drive-applied torque or an external clamp. Velocity feedback comes from a tachometer generator that outputs 1.5 V/1000 rpm, while the incremental encoder with standard mounting supplies digital position data for fine interpolation. These separate feedback signals allow the connected amplifier to regulate rotational speed while also tracking shaft position during rapid starts, controlled stops, and repeated indexing movements.
