This paper proposes the phase voltage estimation method for position sensorless control. The proposed phase voltage estimator estimates phase voltage from the voltage drop of DC link voltage, switching device and diode. The proposed method is verified by the position sensorless control system based on magnetization curves. This study omits phase voltage sensors and offers the low cost position sensorless...
It is known that control strategies for most electrical machines are derived based on machine parameters, which are constant for most of the excitation range. However, due to the salient pole nature of Switched Reluctance Motor (SRM), the machine inductance is not only a function of the rotor angle but also is a function of the excitation current. This complicates the development of control strategies...
In this paper, switched reluctance motor (SRM) to be employed electric vehicle (EV) is designed using finite element method (FEM). The static torque of SRM is estimated with the magnetic field analysis. The temperature rise with time of SRM is estimated with the heat transfer analysis. First, the static torque and temperature rise with time of 600W SRM included in an experiment set, and are compared...
