본문

This paper deals with the design of 1-kW troidal type gyro. In general, gyro can be used as magnet bearing or flywheel energy

storage device. The proposed troidal type gyro is used as a flywheel energy storage device. The gyro is capable of high-speed

rotation in the air. The coriolis effect is taken into account when designing the rotor of the proposed gyro. Also the repulsive power

of the permanent magnet is considered while selecting the shape and the thickness of the magnet. The neodymium is used as

material of the magnets in this paper. The number of magnets are selected accordingly to reduce these torque ripples because

torque ripples is an important factor while designing the gyro. The designed troidal type gyro is verified through the Finite Element

Method (FEM).
