Product Description:

The MAC071C-0-NS-4-C/095-B-0/WI538LV is an AC synchronous servo motor built by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for analog drive systems, the unit converts command voltages into controlled torque so actuators, pick-and-place arms, and conveyor axes can follow motion profiles with minimal delay. Integrated velocity, tacho, and position feedback give the motor the closed-loop response needed for reliable positioning in automated machinery. This arrangement allows the matching drive to monitor motor behavior continuously during speed control and point-to-point motion.

It has a centering pilot of 95 mm, which allows direct fit to gearboxes or flanges with the same locating diameter and helps keep shaft alignment concentric. Heat is removed by natural convection, so installation should allow unobstructed airflow instead of relying on forced-cooling hardware. The rotor is rated for 3000 rpm, and at that speed the built-in tacho generator produces 3 V/1000 rpm for the matching drive. Electrical power is connected through a keyed connector on side B, and the motor and feedback plugs face the same direction for straightforward cable routing. This layout helps keep the connection area compact when the motor is mounted close to adjacent machine components.

The motor uses frame size 071 with length designation C, which gives a compact stack length suited to medium-inertia loads. The stator uses the NS winding, which matches the motor’s electrical characteristics to compatible legacy analog amplifiers across the working speed range. The housing uses the standard connector and sealing format found in the MAC AC Servo Motors line, which supports consistent installation in established machine layouts. These features make the motor suitable for equipment that requires stable speed feedback, compact mounting dimensions, and predictable response from a matched analog drive.
