A proposed novel double-barrier design with single-layer IPMSM is well proved to be effective for reducing pulsation torque, torque ripple and cogging torque, in published work, in which the torque characteristics be sensitive to the unique "connected" double-barrier structure is generally studied. This extended paper presents a few specific models for examining the effect of design variables...
This paper presents motor characteristics and radial magnetic force (RMF) of interior permanent magnet synchronous motors (IPMSM) according to pole/slot combinations. Three IPMSM of 15, 18, 24 slots with 16 poles are selected; 16 poles 15 slots and 18 slots provide high winding factor and 16 poles 24 slots is a general pole-slot combination. Using finite element analysis (FEA) and equivalent circuit...
This paper introduces an accurate phase variable model with detailed evaluation of the force ripple for the linear permanent magnet brushless DC motor (LPMBDCM) drive system analysis. The mover position dependent variables of the physical model are obtained from finite element (FE) solutions by the cubic spline interpolation. Considering the effect of the snubber circuits in the power electronic devices,...
This article discusses about the use of finite-element methods for the calculation of electromagnetic fields in electrical machines and for the determination of machines parameters and characteristics. The solutions offered can be classified as follows: steady state simulation, frequency domain simulation, time domain modeling and simulation, coupled electro-magnetic and thermal problems.
