SUMMARY:

Bearingless motors are compact, frictionless machines; therefore, they are better suited for high-speed applications. Compared to conventional motors, they offer advantages such as reduced friction losses and the elimination of mechanical bearings. However, despite these advantages, the use of motors with magnetic bearings results in increased dynamic complexity of the system and can compromise stability due to electromagnetic couplings and gyroscopic effects associated with the rotor’s angular momentum at high speeds, which motivates the adoption of decoupling techniques. In this context, this work proposes the use of decoupling strategies between the machine’s sides to reduce interactions between them and improve rotor position control performance, utilizing a supervisory system for monitoring and controlling the rotor’s position.
