Recently, it has to design the motor to raise power density because of many necessary application, such as home appliances and hybrid electric vehicles. Power of motor is made up of the torque and speed. So, if the motor which is the same size and shape is designed to raise speed, power and power density are increase. However, it is not easy to control interior permanent magnet (IPM) motor at high speed due to voltage constraint. So, this paper proposed simple method to solve the high speed control problem in the motor design stage, when it assumes that motor drive system has to have current margin. Basic idea is changing number of turns and current while retaining the same magnetomotive force (MMF) in this paper.

영구자석 모터를 구동하는 방법에는 크게 DC (Direct Current) 구동과 AC (Alternating Current) 구동으로 나눌 수 있는데 본 논문에서는 DC 구동과 AC 구동에 따라 IPMSM (Interior Permanent Magnet Synchronous Motor) 모터의 설계 방법을 연구하고 설계의 차이점을 분석하였고 또한 유한요소법 해석을 통해 특성을 분석하였다. 본 논문에서는 DC 구동 IPM의 약계자 제어에 관해 연구하고 설계된 모터를 제작하여 이를 실제 제어에 적용하여 검증하였다. Drive method of permanent magnet motor can be largely divided into two types. One is DC (Direct Current) drive and the other is AC (Alternating Current) drive. This paper deals with study on design of IPMSM (Interior Permanent Magnet Synchronous Motor) considering drive methods, and analysis differences of design and characteristics using finite element method. Besides, this paper proposes field weakening control method for DC drive IPM and verifies this method through experimental results.

Brushless DC Motor (BLDCM) is DC motor and Interior PM Synchronous Motor (IPMSM) is AC motor. Besides their way of control is different. But it is similar that both motors rotate synchronous velocity and use the permanent magnet. So, it is an objective to grasp a tendency of motor design and efficiency of motor through a characteristic comparison of BLDCM and IPMSM with the same power, rotation velocity, torque and input voltage.

In response to the Green Growth, interest of the traction motor is increasing. As Traction Motosr Require wide operation range and high torque density, IPMSMs are suitable for traction applications. In this paper, performance comparison between concentric and distribute winding, with same constraint and requirement.

This paper describes characteristic analysis of linear synchronous motor (LSM) with variable parameters. Linear motor does not use the mechanical coupling for the rectilinear movement. Therefore, structure of linear motor is simple and robust as compared with the rotary motor [1]-[4]. LSM produces the thrust force by interaction between the magnetic field and armature current. There are two types by field location, short primary type and long primary type. In this paper, long primary type LSM is considered for design and characteristic analysis. For characteristic analysis of LSM, analytic and numerical methods are applied. Analytic method for solving the magnetic field distribution of the analytic model is based on the Maxwell’s equations. Using the characteristic equation and equivalent circuit, we analyze the effect of variation of parameters, and then we validate the result by comparing with numerical method by finite element method (FEM). First of all, we design the LSM for transportation system. In a design step, we analyze the characteristics of LSM and it has influence on design parameters. We also apply the equivalent circuit to analysis and to design. And we compare that dc field winding of long stator type LSM is replaced with permanent magnet. We analyze the effects according to changing shapes of shoe in dc field pole and shapes of permanent magnet. And we analyze thrust force, normal force, and back-emf by changing of material of poles, ratio of pole pitch to slot pitch in the stator, load angle, and so on. In conclusion, we compare the analytic method with numerical method for analyzing the effect by variable parameters. This result will be useful of design and forecast of performance without FEM.
