Consideration of the structure and the operation principle of Switched Reluctance Motor (SRM), it is possible to obtain super high speed drive. Therefore, a three-phase 6/2 SRM, the speed of which is 130,000 rpm, is adopted for super high speed drive. Based on the two-dimensional finite element method (FEM), the torque-angle characteristics of 6/2 SRM are analyzed and the motor structure is improved...
A known way to estimate the position of a switched reluctance motor without the use of a shaft position sensor is by excitation of a resonant circuit comprised by an idle motor phase winding and an external capacitor. This paper discusses the influence of the frequency of the sinusoidal excitation signal on the phase inductance. It is shown that the inductance decreases with increasing excitation...
In this paper a torque compensation technique for switched reluctance motor (SRM) is proposed. The conventional torque control with a simple current control loop usually causes large torque ripples and affects the speed response and overall performance of the drive system. The proposed torque compensation method is based on a torque estimation technique using the inductance profile and squared value...
