Product Description:
The MAC090C-1-GD-1-B/110-A-0/-101250 is an AC servo motor produced by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. It converts electrical energy into controlled rotary motion for automation axes that demand tight velocity regulation and repeatable positioning. By combining a permanent-magnet rotor with rapid current control, the unit supports high dynamic response, allowing it to drive conveyors, indexing tables, and similar mechanisms found in manufacturing cells. This makes it useful on axes that need stable low-speed operation as well as quick acceleration between positions.
Thermal management for this model relies on axial surface cooling; airflow is directed along the stator housing by an external blower rated for AC 230 V. This forced-air arrangement extracts heat from the copper conductors so continuous torque can be maintained at elevated ambient temperatures. Because the cooling air passes over the housing surface, heat is removed without liquid lines or a separate cooling jacket. Accurate centering during installation is provided by a pilot diameter of 110 mm, which seats the flange precisely against the machine interface and minimizes radial runout. The assigned winding code is GD, which indicates the phase resistance and inductance values expected by a matching MAC drive.
Motion feedback is delivered through incremental encoder feedback, supplying pulse sequences that the controller converts into speed and position data with sub-millisecond latency. This feedback method supports closed-loop operation with fast response during positioning and speed-control tasks. Mains conductors terminate through a connector on side A, keeping power and encoder cables on the same face for straightforward routing. The assembly is supplied without a blocking brake, so static holding torque must be provided externally when load retention is required after power is removed. As a motor for analog drives, it integrates with control hardware that issues ±10 V commands rather than fieldbus-based setpoints.
