“…These are spoke-type permanent magnet synchronous motor, interior permanent magnet synchronous motor (IPMSM) and surface mounted permanent magnet synchronous motor (Ahn et al, 2020). PMSM (Ahn et al, 2020) Spoke-type permanent magnet synchronous motors have disadvantages such as irreversible demagnetization and postassembly magnetization of permanent magnets (Jeong et al, 2021;Seol et al, 2017). Surface mounted synchronous motors have the disadvantage that the magnets are subject to large centrifugal forces at high speeds.…”

Electric motors are widely used since they are more efficient and environmentally friendly compared to internal combustion engines. Studies in the fields of electric motors and battery management systems etc. used in electric vehicles are increasing day by day. In this study, electric motor design and performance analyzes to be used in electric vehicles are made. Accordingly, firstly, an induction motor design is carried out by considering the design parameters of the induction motor used in Tesla Model S. Then, by taking the stator core of this induction motor as a reference, an interior permanent magnet synchronous motor design, which is very common and advantageous in electric vehicles, is designed. By considering the air gap, magnet angle, magnet thickness, magnet width and magnet type parameters of this motor, the results of analyzes are evaluated in terms of efficiency and torque ripple. As a result of analyzes, efficiency of the final design has been improved by 4.78% compared to the reference induction motor. In addition, the torque ripple of the final design has been improved by 55.17% compared to the initial design of the interior permanent magnet synchronous motor.

“…In some studies, only the eddy currents inside the PM were considered for magnetization analysis [30], [31]. In article published by Hyun-Soo Seol [32], the 3-times magnetizer has been proposed and discussed of its structure and basic principle. In the previous result [32], only the operating principle and concept of the 3-times magnetizing method can be found, but the process of designing the magnetizer cannot be confirmed.…”

The post-assembly magnetizer for flux concentrated rotor of permanent magnet synchronous motor is dealt with in this paper. The design process of a magnetizer that is able to fully magnetize the permanent magnet (PM) inserted rotor core assembly within 3-times is discussed. The number of turns of the Main-pole winding and the Inter-pole winding was determined to maximize the magnetization ratio in each magnetization stage. At the same time, demagnetization characteristic is also examined. When the magnetizer is designed, the number of turns of winding is determined considering the eddy current generated in the core. The magnetization ratio of the PM considering the eddy current effect is compared with the magnetization ratio of the designed magnetizer when the eddy current effect is ignored. Finally, the properties of the finally designed magnetizer are verified through fabricated magnetizer and experiments.

“…Due to this performance of spoke-type PMSM, it was used only for hybrid motors for vehicles in the past, but it is recently being used for home appliances such as washing machines, dryers, and air conditioners. As mentioned above, although spoke-type PMSM has been applied in various ways to the home appliance field, its use is limited due to problems such as irreversible demagnetization and post-assembly magnetization of permanent magnets [13].…”

A Study on the Shape of the Rotor to Improve the Performance of the Spoke-Type Permanent Magnet Synchronous Motor

et al. 2021

This paper describes a study on the improvement of the dehydration performance of the conventional washing machine model. Recently, as interest in improving the dehydration performance of washing machines has increased, the need for a study on a high-speed electric motor has emerged. However, this conventional spoke-type PMSM has difficulty in speeding up due to the following problems. First, field weakening control is indispensable for high-speed operation of an electric motor. This control method is a big problem in causing torque drop and irreversible demagnetization of the motor. Moreover, the centrifugal force increases during high-speed operation, which adversely affects the stiffness of the motor. Therefore, in this paper, a new rotor shape of spoke-type PMSM was proposed to solve the above problem.
