Product Description:

The MAC090C-0-GD-4-C/110-A-1/DI522LV is an AC servo motor produced by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. It is engineered as a motor for analog drives, supplying closed-loop speed and position control to automated equipment that relies on analog command interfaces. By converting drive current into precisely timed torque, the unit supports repetitive indexing, synchronized conveyor work, and tooling operations that depend on predictable rotary motion.

Mechanical alignment begins with a centering diameter of 110 mm, allowing the housing to seat accurately inside standard mounting flanges. Thermal energy is removed through natural convection, eliminating the need for forced-air accessories in enclosed cabinets. The electromagnetic circuit follows winding code GD, which indicates resistance and inductance values used by the analog drive for current limiting. Mains power reaches the stator through a connector on side A, keeping cables on the same face as the feedback plug and simplifying chain routing. Rotor position is measured by an incremental encoder with shock-damped mounting, which limits vibration transmission to the sensor and maintains phase coherence during rapid acceleration.

For holding functions, the motor is supplied with a blocking brake, and its actuation follows the standard option used for the series, allowing load suspension when drive power is removed. Velocity information is refined by the tacho quality channel so that proportional analog regulators can trim speed without digital filtering. When an application requires commutation or velocity loops based on alternate transducers, the combined feedback harness labeled tacho feedback with an incremental or absolute encoder provides both signals in a single lead set, reducing socket count in the cabinet.
