| Abstract: | Taking the features of the voltage waveforms produced bystatic frequence converters as the point of departure,the effectsof time harmonic components on magnetic and electric pathes areinvestigated.Design principle and mothod for the motor areobtained.Effects of the static converter on the dynamic stabilityof the motor are also investigated using a methematical model forthe system which is made up of motor and Converter.It is possibleto find the fine design parameters of the induction motor in bothstatic and dynamic state under operating conditions. |
