MAC090B-1-PD-4-C/110-A-1/DI520LV

The Bosch Rexroth Indramat MAC090B-1-PD-4-C/110-A-1/DI520LV from the MAC AC Servo Motors series is a precision-engineered permanent magnet motor offering robust performance for advanced automation applications. It features a nominal motor speed of 2000 min-1 and delivers a continuous torque at standstill of 7.2 Nm under standard conditions, extending to 10.5 Nm in optimized scenarios. With a continuous current rating of 11.9 A (peaking at 17.4 A), the motor maintains consistent output while an axial surface cooling type system ensures thermal stability during prolonged operation. The compact motor size 90 frame and motor length B profile integrate seamlessly into high-density cabinet layouts without compromising power density.

Material selection and thermal design converge in a rotor with moment of inertia of 36 x 10-4 Kgm2, enabling rapid acceleration and deceleration cycles. The torque constant of 0.67 Nm/A at 20 °C ensures precise current-to-torque conversion for accurate position control. Stator windings exhibit a resistance of 0.97 Ohms and an inductance of 5.1 mH, supporting a maximum peak pulse current of 86 A for short-duration dynamic loads. The 60 ms thermal time constant (45 ms on the winding) provides fast responsiveness to load changes while safeguarding the insulation system.

Certified to operate between 0 and +45 °C ambient (storage from –20 to +80 °C) and at altitudes up to 1000 meters, the MAC090B-1-PD-4-C/110-A-1/DI520LV endures diverse environmental challenges. Weighing just 18 kg, it balances structural rigidity with manageable installation efforts. Whether deployed in servo-driven conveyors, robotic joints, or precision indexing tables, this motor offers reliable, long-term performance under demanding motion control regimes.
