MAC090B-0-PD-4-C/110-B-1/WA612XX

The Bosch Rexroth Indramat MAC090B-0-PD-4-C/110-B-1/WA612XX from the MAC AC Servo Motors series is a robust AC Servo Motor designed for industrial automation with a compact Motor Size 90 frame. This MAC Permanent Magnet Motor features a Motor Length B housing certified to IP65 protection class, ensuring resistance to dilute acids, alkalis, mineral oils, and seawater. Equipped with a Standard blocking Brake and a precise B encoder, it delivers reliable start–stop performance across varied duty cycles. Power is routed via a dedicated Power Connection Side B, streamlining installation and service operations.

Thermal management on the MAC090B model relies on Natural Convection surface cooling, aided by integrated thermo switches in both the winding and stator housing to prevent thermal overload. This brushless design promotes maintenance-free operation and withstands high cyclic loads for continuous start–stop applications. The motor sustains an input current of 11.9 A to produce a continuous torque of 7.2 Nm at up to 2000 rpm. A measured torque constant of 0.67 Nm/A and a winding inductance of 5.1 mH ensure responsive dynamic control and smooth torque delivery under varying load conditions.

With its sturdy IP65 enclosure, compact 90-size frame, and integrated braking and encoder options, the MAC090B-0-PD-4-C/110-B-1/WA612XX offers seamless integration in packaging, handling, and process machinery. The Side B power connector and brushless construction reduce installation complexity and extend service intervals. Bosch Rexroth Indramat’s proven quality in the MAC series guarantees precise, reliable performance in demanding industrial environments.
