- Abstract
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.
