Product Description:

The MAC071B-0-PS-4-C/095-A-0/W1520LV/S001 is an AC servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it is intended to provide precise torque and velocity control in industrial automation axes that still rely on analog velocity or current loops. The unit combines a permanent-magnet rotor with integrated tacho feedback so that legacy drive amplifiers can obtain continuous speed information without digital communication. Its mechanical interface matches standardized mounting dimensions used across the MAC platform.

A centering flange diameter of 95 mm aligns the motor precisely to gearboxes or machine frames and helps keep shaft runout within tolerance. Heat is removed by natural convection, eliminating the need for external blowers in moderate duty cycles. The rotor is optimized for a nominal speed of 4000 rpm, allowing direct coupling to fast positioning mechanics. Torque is transmitted through a shaft with a DIN 6885 keyway, which simplifies connection to standard couplings or pulleys. For quick electrical installation, the power connector is arranged as a connector on side A, which permits parallel routing of motor and feedback cables toward the control cabinet. The internal winding uses code PS, and length variant B sets the overall stack height.

The unit is supplied without a blocking brake, so static holding torque must be generated by the drive or by an external clamp when power is removed. Speed feedback is produced by a built-in tacho generator that delivers 1.5 V/1000 rpm, matching the voltage inputs of analog velocity regulators. For higher-resolution motion control, the same feedback connection can also carry tacho feedback with incremental or absolute encoder signals. Mechanical proportions follow size 071 of the MAC series, which gives predictable mass and inertia values for system layout.
