The larger the capacity, the higher the motor efficiency?

In general, in single-phase capacitor starter motor, the capacitor capacity in series in the starting winding increases by 1 time, the starting torque can only be increased by 50%, and the starting current is increased by 200%. In single-phase capacitive motor, the efficiency of the motor will be reduced by 50% when the capacitance capacity is increased by 2 times. This will make the motor can hardly drive the original load, such as continue to power, the motor is in the load state for a long time, will burn out the winding.

So. When replacing the starting and running capacitors, it is best to choose the same capacitors as the original parameters.
