| Abstract |
This paper proposes an electronic solution for the moving off of usual single phase induction motors fed by the industrial network. This process enables the elimination of passive components (capacitor) generally used in the majority of equipments, and the mechanical centrifugal contactor. The selected principle consists in feeding the two stator phases of the motor accross two thyristor A.C. regulators. Then, the control device of the four thyristors triggers simultaneously performs a frequency division and the phase shift of the statoric phases currents. The aim of theorical study is to show the behavour system possibilities. On theorical level, control sequences are generated by a temporal phasor owing Petri nets properties: the two A.C. regulators are controlled by one generalized graph. This last graph decides the phase shift between the two indor coils. The two rotation senses are possible with the same. Finally, an experimental curves of currents and speed which are cornpared with
simulation results. |
