New technical solutions for the creation of high-speed electromechanical transducer super energy
Ultra-high-speed electromechanical energy converters with a rotor speed of 800 000 min -1. Methods have been developed to address the effectiveness EMPE. In particular the proposal to use a combination of passive magnetic bearings mounted offset together with mechanical bearings for mounting the rotor in the axial direction. This shift in the magnetic rings magnetomechanical bearings needed to create additional axial force, which will unload the mechanical axial bearings. It is also proposed the use of a ring-type coil slotless located bevel. This will reduce pulsation loss, and a rotor shroud and casing to create an additional axial force, which can also be used for additional mechanical unloading of axial bearings. In addition, to reduce the aerodynamic losses of the rotor is proposed to use a friction reducing coating on the bandage shell.
