Product Description:

The MAC071B-0-PS-4-C-095-A-0-WI520LV-S001 belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is a motor for analog drives that supplies closed-loop speed and position control to automation axes that cannot use fully digital interfaces. By pairing the motor with an external drive, machine builders obtain precise torque delivery for pick-and-place tables, feeders, and light tooling where compact envelope dimensions are important.

The mechanical reference surface is a 95 mm centering diameter that aligns the stator in the machine frame. Thermal losses leave the housing through natural convection, so no forced-air or liquid cooling hardware is required. The motor uses winding code PS, which matches its electrical characteristics to Indramat analog servo amplifiers. Rated operation reaches 4000 rpm, allowing high surface speeds on belt or screw transmissions. The power conductors exit through a connector on side A, which keeps the cable bundle on the same face as the feedback lead when the motor is mounted with its B-length body pointing toward the load. Standard tacho quality supports repeatable speed feedback in factory automation.

Tachometer calibration provides a voltage of 1.5 V/1000 rpm, yielding a straightforward speed signal for analog drives. Torque is transferred through a DIN 6885 keyway that mates with common pulley and coupling hubs. The motor is built to size 071, which balances inertia against peak torque for small gantry axes. Position feedback is handled by an incremental encoder with standard mounting hardware, eliminating the need for custom brackets. There is no blocking brake, so any holding function must come from the external drive or the machine mechanics. The B-length housing supports compact installation where available mounting space is limited.
