Product Description:

The MAC071C 0-US-4-C/095-A-0/WI522LV belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. This motor for analog drives is intended to produce controlled torque and speed in closed-loop industrial automation axes that rely on voltage-commanded drive amplifiers. It converts electrical input from the drive into mechanical rotation for positioning or process control tasks. That makes it useful where an existing amplifier platform is retained but reliable servo response is still needed for coordinated machine movement.

The motor uses the 071 frame and a C length stator stack, which set the shaft height, flange dimensions, and overall depth for machine layout alignment. It runs at a nominal speed of 2000 rpm, and the 95 mm centering diameter mates with standard mounting pilots to help keep concentricity under load. The centering pilot also supports accurate alignment between the motor and the mating surface, which helps reduce mechanical offset during installation. Heat is removed through natural convection, so no external blower or liquid circuit is required. Position and speed information come from a feedback arrangement that combines a tachogenerator with encoder hardware, allowing the connected drive to monitor motion continuously.

Electrical behavior is set by the US winding, which matches compatible MAC series drive amplifiers. The integrated tacho produces 3 V/1000 rpm, providing proportional speed feedback for damping during acceleration and deceleration. Power reaches the stator through a connector on side A, which helps route cabling along the machine frame without crossing feedback leads. The motor is supplied without a blocking brake, so any load that must remain held in place when power is off requires external holding force or active torque from the drive. This arrangement keeps the motor assembly simpler and avoids brake wear in applications that do not need built-in holding capability.
