Synchronous Motors If the field circuit of an unloaded salientpole synchronous motor gets suddenly open-circuited, then it runs at a slower speed the motor stops it continues to run at the same speed it runs at a very high speed it runs at a slower speed the motor stops it continues to run at the same speed it runs at a very high speed ANSWER DOWNLOAD EXAMIANS APP
Synchronous Motors For power factor correction, synchronous motors operate at no-load and under-excited fields normal load with zero excitation no-load and greatly over-excited fields normal load with minimum excitation no-load and under-excited fields normal load with zero excitation no-load and greatly over-excited fields normal load with minimum excitation ANSWER DOWNLOAD EXAMIANS APP
