The main function of capacitor C 2 is to start the motor. For this purpose, it is called the start capacitor and capacitor C 1 is called the run capacitor. It improves the power factor of the motor. In general, the starting capacitor C 2 is about 10 to 15 times as large as running capacitor C 1.
W W is the energy in joules, C C is the capacitance in farads, V V is the voltage in volts. The basic capacitor consists of two conducting plates separated by an insulator, or dielectric. This material can be air or made from a variety of different materials such as plastics and ceramics.
Due to the high dielectric constant of these materials, the Class 2 ceramic capacitors offer a higher capacitance per unit volume but have lower accuracy and stability than Class 1 capacitors. They are used for bypass and coupling applications where the absolute value of capacitance is not critical.
As the capacitor is connected all the time, it is selected in such a way to have longer duty cycles, generally the capacitors connected are paper or oil capacitors. They have the torques less than the capacitor start motor but higher than split phase motor.
capacitor plates i = dq . And thus we have, dt The constant of proportionality C is referred to as the capacitance of the capacitor. It is a function of the geometric characteristics of the capacitor - plate separation (d) and plate area (A) - and by the permittivity (ε) of the dielectric material between the plates.
Hence, a higher capacitance value can be obtained by fabricating the capacitor with high dielectric constant, by reducing the distance between the conducting plates or by increasing the area of conducting plates. A parallel plate capacitor stores an absolute extent of energy until it reaches to the dielectric breakdown voltage.
