MAC090B-0-ND-4-C/110-B-1/WI569LX

The MAC090B-0-ND-4-C/110-B-1/WI569LX from the MAC AC Servo Motors series by Bosch Rexroth Indramat delivers precision performance with a nominal motor speed of 3000 min-1 and a torque constant at 20 °C of 0.58 Nm/A. This permanent-excited AC servo motor features a low rotor moment of inertia of 36 x 10-4 kgm2 for minimal dynamic lag, while its windings resistance at 20 °C of 0.75 Ohm ensures efficient current-to-torque conversion. Designed for demanding automation tasks, the model incorporates an integral blocking brake rated at 6.5 Nm to maintain position integrity in power-off conditions. Its compact Motor Size 90, Motor Length B footprint and Mass of 18 kg provide an optimal power-to-weight ratio for high-density installations.

Engineered for reliability, the MAC090B integrates natural convection cooling and a thermal time constant of 60 minutes to withstand extended duty cycles without forced-air equipment. The drive electronics support a peak pulse current of 98 A while protecting against overload via embedded thermal sensors. A continuous torque at standstill of 6.7 Nm guarantees ready torque on demand for static loads, and the servo’s power connection on Side B simplifies cabinet wiring and feedback integration. These attributes make it a versatile choice for packaging, robotics, textile, and general industrial applications.

Protected to IP65, the MAC090B accommodates ambient temperatures from 0 °C to 45 °C and resists water, dust, and contaminants in harsh environments. Its dual-flange design (B05 and B14) supports multi-orientation mounting and can handle significant radial loads through robust bearing assemblies. With brushless construction and lifetime-lubricated bearings, this Bosch Rexroth Indramat servo motor minimizes maintenance while delivering consistent, high-density performance across a wide range of industrial systems.
