This paper deals with a design method of an external permanent magnet (PM) synchronous motor (PMSM) using concentrated winding (wound around one tooth). The machine is used for the electrical motorization of a small urban hybrid vehicle. Such an application leads to strong design constraints, such as weight limitation, high starting torque, compactness etc. To achieve the design of the machine, an...
This paper investigates the iron loss and torque characteristics of inverter-fed spoke type interior permanent magnet synchronous motor (IPMSM) optimized for sinusoidal distributed back-EMF. First of all, an optimal design procedure is introduced to effectively optimize the rotor pole surface to reduce the distortion of back-EMF in the spoke type IPMSM. Then, the finite element method (FEM) results...
This paper proposed the optimal rotor bar design of the permanent split capacitor (PSC) single-phase induction motor. The starting torque and motor efficiency were used as parameters for optimization. The Taguchi method was used in experimental designs for optimization of multiple parameters and the finite element method (FEM) analysis was used to compute and analyze the starting torque and motor...
This paper presents the optimal barrier design in single-phase LSPM (line-start permanent magnet motor) considering the efficiency. The line-start permanent-magnet motor is a synchronous hybrid PM/reluctance motor that is being developed for applications including compressors of air conditioner that require a high-efficiency alternative to the induction motor. To consider nonlinear characteristics,...
