Recently, due to the price fluctuation and supply instability of rare earth mineral resources, there has been a lot of development of electric motors using non-rare-earth permanent magnets. As a result, motors using Dy-free permanent magnets and ferr

Conventional surface mounted permanent magnet synchronous motor (SPMSM) at high speed has large iron loss in the stator and eddy current loss in the rotor. The higher the eddy current loss, the higher the rotor temperature. Therefore, a plan to reduc

Abstract It has advantages such as high power density and miniaturisation when the motor operates at high speed. However, as a side effect, the loss density is much higher than that of a constant speed motor. In addition, a retaining sleeve is insert

Permanent magnet synchronous motors (PMSMs) are highly affected by magnetization, which determines the magnetization level in the permanent magnet (PM). There are three main magnetization methods: single-unit, stator coil, and post-assembly magnetiza

Demand for high-speed motors is increasing. Surface-mounted permanent magnet synchronous motors (SPMSM) used in high-speed applications have magnets attached to the rotor, so there is a risk of damage and scattering due to centrifugal force as the sp

Axial flux motors have a large output density with a large outer diameter of the motor and a short axial length. Since it is advantageous in short axial length, the axial thickness of motor components becomes a very important parameter when designing

Owing to the shortage of rare-earth magnetic materials, various methods are being examined to reduce the use of magnets. One of these is a consequent pole. The consequent pole model can reduce the use of magnets by 50% using only one pole of the magn
