Study of Pmfsm, Pmsm and Srm, as Possible Solutions in Automotive Drives

In the last decades the automotive industry is one of the main sources of air pollution and a major consumer of oil resources. Future oil depletion and environmental damage produced by the gas emissions push automobile industry to improve traction efficiency and to reduce oil consumption and pollution.Because of this requirements, the hybrid electric vehicles have become very popular. Nowadays, it is difficult to imagine the future without hybrid electric vehicles. These days, the technological innovations have led to the increased use of new types of electrical machines in hybrid electric vehicles such as permanent magnet flux-switching machine. The main purpose of this research is to offer an overview on some electrical motors for propulsion of the hybrid electric vehicles power train. Three different electrical motors, respectively permanent magnet flux switching motor, permanent magnet synchronous motor and switched reluctance motor, are fully analyzed and the obtained results are compared, the focus being on the torque density value.
