| Abstract: In order to analyze the performance of the six phase induction motor speed regulating system supplied with the voltage source inverter, the dynamic mathematical model of six phase induction motor in the d q coordinate system is got by coordinate transformation, on the foundation of the dynamic mathematical model of six phase induction motor in the A B C coordinate system. The Space Vector Pulse Width Modulation (SVPWM) is adopted to modulate the six phase voltage source inverter. In the environment of MATLAB/SIMULINK, the simulation model of six phase induction motor speed regulating system supplied with the SVPWM voltage source inverter is established, and the starting and braking processes of the six phase induction motor are simulated. The simulation results show the advantages of the system: small torque ripple, small stator harmonic current, well transient response and steady response. |
