The interest in permanent magnet synchronous motor is present in a wide area of applications, ranging from high-performance servo drive to line-start application. The are mainly two reasons for this trend: first low rotor losses and second the falling prices of high-energy magnets. In this paper the dynamic characteristic of the line-start permanent magnet synchronous motor are described and compared with those if the squirrel-cage induction motor through the simulation to find the characteristics of the permanent magnets and the rotor bar in the line-start permanent magnet synchronous motor..

The paper is described about the statatic and dynamic characteristics analysis of Axial Flux Reluctance Motor(AFRM) with the axial flux path against the rotating direction. To estiamte the performance considered the nonlinearity of magnetic circuit, the modeling parameters of AFRM are computed by the finite element method as functions of input current and angular displacement. The current, torque, back EMF and output power wave of AFRM are simulated from the motion equation by MATLAB/Simulink, and compared linearity simulation results with the nonlinearity ones.

Permanent magnet brushless motors are increasingly being used in high performance applications. The advantage of using a BLDC motor is that is can be controlled to have the speed-torque characteristics similar to that of a permanent magnet DC motor. In addition, the BLDC motor has low ineria, large power to volume ratio, and low noise as compared with the permanent magnet DC servo motor having the same output rating. This paper is proposed the design method of Outer Roter BLDC for a blower fan by the magnetic equivalent method. In order to compute and estimate the performance parameter of Outer type BLDC, the dynamic model and charateristics analysis of BLDC is simulated by Matlab.
