Udoskonalony dobór pojemności kondensatora przy pracy jednofazowej silnika indukcyjnego z trójfazowym uzwojeniem stojana

The paper deals with problems connected with the single-phase operation of an induction motor with three-phase stator winding. Simulation calculations have shown that the pulsating torques of great amplitudes appears during the single-phase work of the induction motor. The mechanical pulsations generate vibration and noise. The new conception of the choice of the optimum value of capacitance has been presented. The capacitor ought to ensure both the great mechanical power of the motor and decrease of vibration and noise. Suggestions for the selection of the optimum capacitor, developed on the basis of simulations, have been verified experimentally.
