Abstract:
According to the requirement of micro satellite, a type of structure of HTS maglev energy storage and attitude control flywheel was proposed.Based the H-method, the magnetic field and levitation force of permanent magnetic(PM)structure coupled with HTS stator were analyzed through simulation calculation.Comparing three types of permanent magnetic structure, the Halbach configuration was adopted for its largest levitation force and lowest magnetic field in the sensitive component zone.By adjusting height and width of central magnet in Halbach configuration and keeping the size of the PM zone, aiming at largest levitation force and limiting external magnetic field, the optimal PM structure with levitation force about 1 084 N was obtained.
