    ABSTRACT: In this paper, design and optimization of interior permanent magnet motor for electric power steering application is studied. IPM motors advantages in automotive systems are discussed. Optimization is done with different objective function such as power to weight and magnet volume. After obtaining the motor parameters, we evaluate the performance of entire system through some different tests. Simulation results show that the system performance can improved using an IPM motor and drive because of its high torque density and capability of flux weakening operation. With the EPS logic for the reduction in steering torque, the driver can turn the steering wheel with a significantly reduced steering torque. With the EPS control to return to center performance, a quick response of steering wheel without overshoot after cornering can be obtained by proper control of assist motor.

    ABSTRACT: Electric power steering is a new kind of power steering which is developing rapidly these years due to their superior energy efficiency and energy conservation. This paper presents the design criteria of a tubular linear motor with interior permanent magnet and a tubular interior permanent magnet linear motor is designed and optimized with respect to weight and force ripple for Electric Power Steering application. Such an application requires low motor vibration and low force fluctuations which are considered in design process. A finite element analysis is used to validate the results obtained from the analytical model, comparing the magnetic field quantities as well as the mechanical force.

    ABSTRACT: As the development of microprocessors, power electronic converters and electric motor drives, electric power steering system which uses an electric motor came to use a few year ago. Electric power steering systems have many advantages over traditional hydraulic power steering systems in engine efficiency, space efficiency, and environmental compatibility. This paper deals with design and optimization of an interior permanent magnet motor for power steering application. Direct search method is used for optimization. After optimization and finding motor parameters, an interior permanent magnet motor and drive with mechanical parts of electric power steering system are simulated and performance evaluation of system is done.

    ABSTRACT: As the development of microprocessors, power electronic converters and electric motor drives, electric power steering (EPS) system which uses an electric motor came to use a few year ago. Electric power steering systems have many advantages over traditional hydraulic power steering systems in engine efficiency, space efficiency, and environmental compatibility. This paper deals with design and optimization of an interior permanent magnet (IPM) motor for power steering application. Simulated Annealing method is used for optimization. After optimization and finding motor parameters, An IPM motor and drive with mechanical parts of EPS system is simulated and performance evaluation of system is done.
