Product Description:

The Bosch Rexroth Indramat MAC063D-0-JS-4-C/095-B-0/WI522LV is an AC servo motor in the MAC AC Servo Motors series. It is intended for analog drive systems where closed-loop speed and position regulation are required on assembly lines, pick-and-place units, and light machine tools. The motor interfaces directly with compatible Indramat analog controllers, converting commanded current into controlled torque and rotary motion. Its compact construction makes it suitable for axes where installation space is limited but repeatable response is still required.

The mechanical interface uses a centering diameter of 95 mm, allowing the flange to seat accurately on gearboxes or brackets without shims. Heat produced by the stator is removed through natural convection, so extra fans or liquid circuits are unnecessary when normal ambient airflow is available. Rated shaft speed reaches 3500 rpm, matching the rotor and magnetic design for mid-range cyclic duty. Electrical behavior follows the JS winding code, which corresponds to the phase resistance and inductance used by matching analog drives. Power conductors exit through a connector on side B, which helps when the opposite face is blocked. Position data is returned by an integrated incremental encoder, allowing accurate speed regulation and position tracking during operation.

A separate tacho generator supplies 1.5 V/1000 rpm, giving the analog controller an additional speed-related signal for stable low-speed response. The motor has a 063 frame size with length class D, which keeps rotor inertia low for rapid start-stop motion while preserving steady behavior during short dwell periods. It is supplied without a blocking brake, so any vertical axis that must hold position during power loss needs an external mechanical lock or a torque-holding function from the drive. The feedback arrangement assists the controller during speed correction and supports smooth motion throughout the normal operating range.
