MAC090B-0-JD-4-C/110-B-0/WI531LX/S001

The Bosch Rexroth Indramat MAC090B-0-JD-4-C/110-B-0/WI531LX/S001 from the MAC AC Servo Motors series is a high-performance AC Servo Motor engineered for precision automation tasks. This Motor Size 90 frame and Motor Length B design deliver a nominal speed of 3000 RPM while maintaining compact dimensions and robust build quality. Rated for a continuous torque at standstill of 6.7 Nm with a continuous current at standstill of 18.2 A, it offers reliable start-up and holding capabilities. The absence of a blocking brake simplifies maintenance and reduces mechanical complexity.

Thermal management and winding characteristics ensure consistent output under demanding conditions. The motor features a thermal time constant of 60 min and windings inductance of 2 mH, allowing predictable heating behavior during extended operation. A windings resistance at 20 deg C of 0.38 Ohm contributes to accurate current control and minimal thermal drift. With a maximum peak of pulse current of 137 A, the unit can handle short-duration high-torque demands without compromising system stability. Cooling is provided by Natural Convection, ensuring silent and maintenance-free operation in enclosed or low-airflow environments.

Feedback and connectivity are addressed through an incremental encoder with standard mounting and a power connection type connector to side B, facilitating straightforward integration with TDM, KDS, and DSC drive controllers. The motor’s encoder mounting and robust power interface reduce installation time and improve signal integrity. Without a holding brake, the design maintains a lean profile while still catering to machine tools, packaging systems, and robotic applications requiring rapid, accurate positioning.
