Based on analysis of sources of the noise of switched reluctance motor (SRM), the paper puts forward methods to reduce noise in terms of torque ripple and phase change from the point of control view. In the low speed stage, phase current closed-loop segmented according to the sine and cosine curve, maintain a constant torque to reduce the torque ripple. Put forward soft turn-off method at the time...
A new approach to automatic control of excitation parameters for the switched reluctance motor (SRM) is presented. A turn-on and turn-off angles play important roles in developing electromagnetic torque in SRM. The value of excitation angles are usually variable and depend upon the motor speed and other parameters of the inverter that excites the SRM. As the motor speed increases the shape of the...
