Product Description

Many users laud Bosch Rexroth for the reliability, durability, and long-lasting performance of its drive and motion control units. The company’s MAC AC servo motors are permanent magnet-excited motors used in packaging machinery, printing presses, and handling equipment t.

The MAC090C-0-KD-4-C/110-B-1/WA611XX is a MAC model designed and manufactured by Bosch Rexroth. This brushless motor comes equipped with thermo switches in its windings to monitor temperature levels. The monitoring system is essential in initiating mechanisms that safeguard the motor from thermal overload, preventing irreversible damage. With natural convection comprising its cooling system, it efficiently dissipates heat from its stator windings to the outside walls of its housing. Being an electronically commutated motor, the MAC model is well-suited for continuous start-stop operations with high repetition rates, thanks to its high cyclic load capacity. This feature helps prevent fatigue-induced failures that may arise after repeated stress cycles.

Operating the MAC090C-0-KD-4-C/110-B-1/WA611XX maintenance-free is made possible by its lifetime-lubricated bearings. These bearings not only eliminate the need for relubrication but also prevent the accidental use of contaminating lubricants. They also reduce energy losses by preventing friction. The motor's housing is coated with a black prime layer that shields it from weathering, yellowing, and chalky buildup. This coating is also resistant to dilute acids and lyes. The MAC model is fitted with a blocking brake with a holding torque of 6.5 Nm. The brake operates on the closed-circuit principle, ensuring that the servo axes remain held when the machine is powered off. Since the MAC motor's rotor is built with rare-earth materials, it has low inertia and a favorable torque-inertia ratio for a highly dynamic performance.
