“…The synchronous speed is proportional to the pole-pair number, so the speed regulation range can be extended by polechanging (PC) operation. Based on the PC concept, three kinds of PC motor have been reported, including the PC induction motor (PC-IM) [10]- [15], the PC dual-speed PM motor (PC-DSPMM) [16]- [18], and the PC memory motor (PC-MM) [19] [20].…”

A flux switching permanent magnet (FSPM) motor is designed and optimized in this paper to achieve high torque density and expanded speed regulation range from a design viewpoint of pole-changing (PC). Based on the field modulation theory, the PM field in the FSPM motor is modulated by the stator and rotor teeth, generating rich harmonics with different pole-pair numbers in the air-gap flux density. By adopting an appropriate slot pole combination, working harmonics with different slot pitch angles are obtained to establish a basic of the PC-FSPM motor. Then, different working harmonics can be used to achieve different energy conversions with different winding configurations, so the PC operation can be performed to realize the high torque and wide speed regulation range by switching the working modes. Based on the field modulation theory, the operation principle of conventional and PC-FSPM motors are analyzed and compared. Then, according to the design principle of PC-FSPM motor, a 24/22-pole PC-FSPM motor with E-core is designed and optimized by a multi-level optimization method. Finally, the electromagnetic performances are analyzed by finite element analysis and the test results of the prototype verified the feasibility of the motor.

“…In addition, impedance of both windings is adjusted by geometrical changes or additional capacitors to split into two-phase sources. Even though decreasing prices of inverter-fed drive have spread to operate two-phase or three-phase motors electronically, but SPIMs still have strong merits for its simplicity and maintenance [1][2][3][4].…”

This paper varies load conditions in a single-phase induction motor and deals with consequent effects on the electromagnetic characteristics in terms of a balanced and unbalanced operation. Based on a balanced-load condition, the magnetic field, electromagnetic losses, magnetic torque are quantified by the time-stepping finite element method at six different loads. The spatial distribution of the air-gap magnetic field are investigated to characterize the existence between the load variation and unbalanced operation. The components of electromagnetic losses are analyzed in terms of main parameters degrading the operating efficiency according to the load variation. The result can show the importance of building the magnetic balance for a high performance, and the design guideline for SPIMs running at multiple operating points is discussed.

“…Despite the advances on the starting and steady-state performance of such motors [4][5][6][7][8][9][10][11], the fixed single-speed restriction is still in place. Recently, there have been some studies on the design of two-speed LSSMs [12][13][14][15][16][17][18]. In [12], a two-speed line start motor is presented for efficiency improvement of compressor motors.…”

This article presents a design improvement of the dual-pole, two-speed line start permanent magnet (LSPM) synchronous motor. For this purpose, the operational performance of the motor with dual-pole structure is first compared with the conventional single-pole motor to identify its performance limitations. Next, the structure of the dual-pole rotor is modified accordingly to address the related limitations. The proposed, modified design reduces the number of PMs in the rotor structure and offers a better steady state and transient performance. The motor is analysed using 2D finite element analysis (FEA), and results are verified by experimental tests on the motor prototype.
