MAC090B-0-PD-4-C/130-B-1/WI533LX/S012

The MAC090B-0-PD-4-C/130-B-1/WI533LX/S012 from Bosch Rexroth Indramat, part of the MAC AC Servo Motors series, is a high-precision AC Servo Motor designed for demanding automation applications. This MAC Permanent Magnet Motor features a Motor Size 90 frame and a Motor Length B housing, optimized for compact installations. It employs Natural Convection cooling to maintain optimal operating temperatures without additional fans, ensuring reliable performance in controlled environments. The motor’s robust construction and advanced design support extended duty cycles while minimizing maintenance requirements.

Delivering a speed rating of 2000 RPM, the motor generates a rated output torque of 7.2 Nm at a rated output current of 11.9 A, with a torque constant of 0.67 Nm/A at 20 °C. Its winding characteristics include a resistance of 0.97 Ω and an inductance of 5.1 mH, providing predictable current-to-torque response. A thermal time constant of 60 minutes allows for stable operation under transient loads, and the motor is specified for ambient temperatures from 0 to 45 °C to avoid derating or component stress.

Mechanically, the unit is fully sealed to IP65 standards, preventing dust ingress and low-pressure water jets from compromising internal components. It includes a Standard blocking brake rated for 6.5 Nm holding torque, weighing 0.5 kg, and an incremental Encoder with standard mounting for precise feedback. The power connection on Side B and integrated tacho generator simplify installation, though power and feedback connectors must be sourced separately. With a base mass of 18 kg (18.5 kg including brake), this servo motor balances rigidity and weight for versatile use in robotics, packaging, and motion-control systems.
