MAC090A-0-ZD-4-C/110-B-1/WI531LX

The Bosch Rexroth Indramat MAC090A-0-ZD-4-C/110-B-1/WI531LX from the MAC AC Servo Motors series offers a robust solution for precision motion control with a continuous current at standstill of 8.1 A and a nominal speed of 3000 min-1. Designed as an AC Servo Motor with a motor size 90, it features a lightweight rotor inertia of 20 x 10-4 kg·m2 that ensures rapid dynamic response and accurate positioning. Equipped with a standard tacho type incremental encoder mount for direct feedback, the unit delivers consistent performance in demanding applications. Its winding characteristics, including a windings inductance of 1.9 mH, support smooth current transitions and minimize electrical noise.

Natural convection provides the primary cooling method, eliminating the need for auxiliary fans and reducing maintenance. The housing is finished with a black prime coat for corrosion resistance and durability, while the compact motor length A frame simplifies integration into tight machine layouts. Rated to protection class IP65, the motor withstands dust and water ingress, making it suitable for rugged industrial environments. A thermal time constant of 45 min ensures predictable temperature rise for safe continuous operation.

With its compact form factor, high torque density, and precise feedback interface, the MAC090A-0-ZD-4-C/110-B-1/WI531LX is ideal for robotics, CNC machinery, and automated assembly systems. The combination of F-class insulation, resilient enclosure, and built-in braking options delivers reliable performance and secure load holding under power-off conditions. Engineers will appreciate the motor’s versatility and proven reliability in mission-critical applications.
