Why Single-Phase Induction Motors Need Capacitors
Run capacitors are constructed to be used continuously while the AC motor is running, unlike start capacitors which are only in the circuit for a short period of time just to start the motor. This is why low loss polymer capacitors are used as run capacitors because of a longer life time and lower loss of current, opposed to electrolytic capacitors which are ideal for momentary use.
