When the Halbach array is applied to linear motors, the amplitude of the fundamental wave of the air gap flux density can be increased, and the air gap flux density distributes sinusoidally. In this paper, by FEM, the effect of Halbach array is contrasted with the effect of tradition permanent magnet structures on the sinusoidal distribution and the fundamental amplitude of the air gap flux density,...
There are many inherent advantages on multi-phase PMSM, its prospect is very optimistic. A novel six-phase disc permanent magnetic synchronous motor which adopts a one-rotor-two-stators configuration is presented. The principle and structure are depicted. FEM is used to analyze the no-load magnetic field characteristics of this motor, and this paper contrasts the effect of permanent magnet thickness...
