- Abstract
- This paper presents a novel 2-phase 6-pole permanent magnet synchronous motor (PMSM) with asymmetric U-core stator structure. The construction and parameters of the novel two-phase U-core PMSM are compared with a conventional single-phase U-core PMSM and a two-phase round-core PMSM. Then transient characteristics such as torque, back-emf, and power loss of the three PMSMs are analyzed by using 2-D Finite Element Method (FEM). Under the same condition o f rated input current, synchronous speed, output power and rotor dimensions, FE results show that the two-phase PMSM with U-core stator has less torque ripple than single-phase U-core PMSM, less power-loss and higher efficiency than the two-phase round-core PMSM.
