“…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.…”

“…However, this motor operates as an IM at the high-speed zone. The pole changing method based on variable pole numbers for the stator and the rotor is presented in [13][14][15][16][17][18]. In [14], rotor with dual saliency enables the motor to operate as a synchronous reluctance motor (SynRM) at both low-and highspeed regions.…”

“…In [15,16], rotor with hybrid polarity enables the motor to operate as a synchronous PM motor at high speed and a synchronous reluctance motor at low speed. In [17,18], the rotor design with dual magnetic polarity enables the motor to operate solely based on electromagnetic torque as a PM synchronous motor at both low and high speeds. The later design with dual magnetic polarity offers a better performance characteristic at steady state but some challenges are yet to be solved.…”

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.

The paper suggests a design and optimisation approach for a consequent‐pole line‐start permanent magnet motor (CPLSPM) with flexible pole arc coefficients and high utilisation of rare‐earth (RE) materials, without the need for a variable frequency drive. The presence of dual‐sided slots and adjustable pole arc coefficient sets CPLSPM apart from other types of motors, making the analysis of its cogging torque more complex. Taking into account the double‐sided slotted and flexible adjustable pole arc coefficient, a cogging torque and airgap flux density model was established, and the influence of the pole arc coefficient on the characteristics of the cogging torque and airgap flux density of CPLSPM was analysed. The authors conduct multidimensional optimisation considering the coupling of multiple parameters to obtain a CPLSPM with minimal RE material usage, low cogging torque and excellent start‐up and steady‐state performance. Finite element simulation data are presented to validate the factors affecting the cogging torque and the feasibility of the proposed less‐magnetic CPLSPM design. Finally, a prototype of a 750 rpm/2.2 kW CPLSPM is built, and performance testing is carried out for comparison, and applied to submersible mixers.
