Study on dynamic characteristics of three-phase single-side linear induction motor used in elevator
Abstract
Linear induction motor have open magnetic circuits so the flux is discontinuous from one pole to the other where it is cut off at the beginning and at the end, making the magnetic field in the motor asymmetric as well as the eddy currents in the secondary circuit cause non-sinusoidal magneto-motive force and is called end effect and eddy current . The application of this motor type in elevators has also been interested, but in order to perform well and develop this drive type, it is necessary to have a research background on the working characteristics of motor, especially the dynamic characteristics. The paper deals with the study of dynamic characteristics of three-phase single-side l inear induction motor used in elevator in the no-load and loaded elevator, variation of frequency and asymmetric power supply. The simulation method on Matlab software is used in this study.
