Product Description:

The MAC090C-0-GD-4-C-110-A-1-WI520LV-S001 is a brushless AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It serves as a rotary actuator in analog drive systems, supplying closed-loop torque and speed control in machine tools, printing lines, and handling stations where consistent positioning is important to the process. The unit is classified as a motor for analog drives, so its signal levels, connector pinouts, and operating range match legacy Indramat drive modules used in many installed machines. Its brushless construction also reduces routine wear associated with mechanical commutation and supports continuous industrial duty.

A centering diameter of 110 mm lets the housing seat precisely against the mating flange for accurate alignment during installation. The GD winding code indicates the electrical constants used for mid-range torque output, and heat is removed by natural convection, so no auxiliary fan or liquid circuit is required. The flange-mounted layout helps keep rotor alignment stable when the motor is coupled directly to a gearbox or machine plate. Power conductors enter through a keyed circular connector on side A, which keeps cable routing on one face of the machine frame. For load holding during shutdown, a standard blocking brake is mounted on the shaft end and engages automatically when DC power is removed to help prevent back-driving from gravity or residual inertia.

The motor includes encoder feedback within its feedback stack, allowing the drive to monitor shaft movement while maintaining stable control response. The primary commutation device is an incremental encoder mounted in the standard mechanical position, which preserves the motor's axial envelope and supports consistent position tracking. Velocity loop linearity is supported by a standard tacho that outputs a proportional DC voltage based on shaft speed. Continuous motion feedback lets the connected amplifier correct speed deviation during load changes and maintain repeatable axis behavior during extended production cycles.
