Product Description:

The MAC071A-0-HS-3-C/095-A-0 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It is intended for use with analog drives that regulate motion through external control electronics. In automated transfer lines, packaging stations, and handling modules, it turns reference voltages from earlier-generation controllers into closed-loop torque or speed for repeatable axis motion.

The motor has a centering diameter of 95 mm, which aligns the housing in a machine frame and maintains concentricity between the motor and load. Rated speed reaches 2000 rpm, giving the drive a balanced mix of torque and responsiveness for medium-duty positioning. The electromagnetic system uses winding code HS, and that winding matches the voltage, current, and inertia pairing expected by the analog amplifier. Heat is removed through natural convection, so airflow around the housing must remain unobstructed during continuous operation. For velocity feedback, the built-in tacho generator supplies 3 V/1000 rpm, a signal level that connects directly to the speed regulator input. Motor length A is the shortest build in the 071 frame, which reduces installation depth while retaining the full stator diameter. The tacho quality is standard, indicating the permissible ripple and linearity values of that feedback device.

This configuration is delivered without a blocking brake, so external holding methods are required if the shaft must stay fixed when power is off. The motor includes tachofeedback and a second shaft end, so an encoder or mechanical load sensor can be added on the rear extension when tighter accuracy is required. That arrangement also leaves the main shaft free for the driven load at the front of the motor. Power leads exit through a connector on side A, simplifying cable routing in cabinets that share a common motor orientation. The frame designation 071 matches the series mounting pattern and housing size used for this motor platform.
