MAC090A-1-RD-4-C/110-A-0/WA612XX

The Bosch Rexroth Indramat MAC090A-1-RD-4-C/110-A-0/WA612XX from the MAC AC Servo Motors series is a compact yet powerful AC servo motor featuring a Motor Size 90 frame and Motor Length A construction. This variant includes an A-side power connection and an integrated encoder interface while omitting a holding brake for streamlined installations. Its Mass of 12.5 kg and Surface Cooled design with axial fan cooling ensure efficient thermal management in densely packed cabinets. Designed for closed-loop control, the MAC090A-1-RD-4-C/110-A-0/WA612XX delivers consistent performance across a variety of industrial automation tasks.

Equipped for demanding applications, this motor provides a Continuous current at standstill of 11.4 A (16.3 A peak)^5) and a Maximum peak of pulse current of 76 A to handle rapid torque demands. It develops a Continuous torque at standstill of 3.5 Nm (5.0 Nm peak)^5), driven by a Torque constant at 20 °C of 0.34 Nm/A. The motor’s electrical characteristics include a Windings inductance of 3.2 mH and a Windings resistance at 20 °C of 0.56 ohms, facilitating precise current control. With a Nominal motor speed of 3000 min^-1 and a Thermal time constant of 45 min (30 min)^5), it maintains performance stability under sustained loads.

The MAC090A series leverages the built-in tacho feedback mechanism—either absolute or incremental encoder—to automatically adjust output against load variations, delivering high positional accuracy. Its electronic commutation via permanent magnets ensures low maintenance and high power density in a compact footprint. This robust servo solution is ideal for machine tools, packaging systems, and high-speed handling equipment where rapid response and reliable speed regulation are crucial.
