MAC090B-0-PD-3-C/110-B-1

The Bosch Rexroth Indramat MAC090B-0-PD-3-C/110-B-1 from the MAC AC Servo Motors series delivers high-performance actuation for demanding industrial automation. Rated for ambient temperatures from 0 °C to 45 °C and protected to IP65 with class F insulation, it withstands dust and low‐pressure water jets in harsh environments. It maintains continuous performance with a continuous torque at standstill of 7.2 Nm and handles a continuous current at standstill of 11.9 A while spinning at a nominal motor speed of 2000 min-1. The brushless design and lifetime‐lubricated bearings yield high reliability under substantial axial and radial loads.

With a torque constant at 20 °C of 0.67 Nm/A and a winding inductance of 5.1 mH, the MAC090B optimizes current-to-torque conversion for precise control loops. Its rotor moment of inertia of 36 x 10-4 kgm2 and thermal time constant of 60 minutes ensure stable thermal behavior during cyclic operation. Peak performance is supported by a peak pulse current of 86 A and natural convection cooling type, eliminating the need for external fans or liquid cooling. The motor size 90 frame with motor length B and versatile flange design featuring through holes and threaded mountings allows straightforward, orientation-free installation.

Electrical connection is simplified via a power connection on Side B, and optional plain or keyed output shafts facilitate form-fitting or non-positive couplings. Weighing 18 kg and featuring an available 6.5 Nm blocking brake, this model is ideal for extreme applications that require continuous torque and compact dimensions. It also offers a centering diameter of 110 for precise shaft alignment in high‐precision systems.
