Zwarcie udarowe jako diagnostyczna metoda pobudzania do drgań silnika indukcyjnego

The study paper describes dynamic mathematical model of an induction motor. This model has been applied to simulate investigations and to calculate a peak value of electromagnetic torque during short circuit shock. Also presented are results of experiment investigations of a high power induction motor vibration, which has been initiated by a short circuit shock method. The measurement results of vibration when using two other methods are included. Consistence of measurement results proves suitability of a short circuit shock method to be applied to vibration testing of an induction motor.
