Get PriceSingle phase Motor Capacitor Calculation calculator
The calculation for Voltage Rating of the Capacitor: The voltage rating of the capacitor is equal to the product of the voltage measured at both ends of the main winding in volts and the root of one plus turns ratio n square. V (C) = Vp √(1+n 2) n is equal to the ratio between the main/auxiliary winding turns.

Get PriceComplete Guide to Bad AC Capacitor Diagnosis & Repair
Essentially, a start capacitor helps to start the motor, by giving a voltage boost during start up. A run capacitor keeps a motor running by inducing a phase shift in the stators to help the rotor "grab" the next stator and turn. When a run capacitor goes bad, this phase shift does not occur and causes the motor to work harder, and in turn ...
