An electric motor capacitor is a device that first stores, then releases an electrical charge to help start an electrical motor (starting capacitor) or to keep it spinning (run capacitor) - the electrical charge or potential energy stored in the capacitor is used to give a power boost to the motor to help it overcome inertia - to start rotating. Multiply 0.5 times the square of the voltage. Assuming a start-up energy of 0.00033 joules, you obtain 0.33 divided by 66.1 which equals 5.0 times 10^-6 farads. Divide the start-up energy requirement, in joules, of the motor by "x" to arrive at the capacitor size needed in farads. Capacitor induction motors are widely used for heavy-duty applications requiring high starting torque. or Best Offer. Getting the right size capacitor for an electric motor could mean the difference between starting the motor or not. If it is not attached to the motor at two points it needs to be replaced.

This is labeled by the lowercase Greek letter "µ" — pronounced as "mu" — followed by the letter "f." If you have an auto-ranging multimeter it will do this step for you automatically. A start capacitor is only used in the motor circuit for a second or two when it first starts to turn. The housing is moisture- and oil-resistant plastic. The interaction between the inductance of the motor windings and the capacitor's capacitance causes that winding to be about 90 degrees out of phase with the main winding. Once the motor is up to speed, the start capacitor disconnects and is not used again until the next time the motor starts. Capacitance is measured in microfarads. Turn off the power to the motor then disconnect it from the power source. Round, molded cases can protect start capacitors from oil, dirt, moisture and grease, helping prolong maintenance-free performance and reduce replacement costs. The starting winding is automatically removed by a centrifugal switch as the motor accelerates. Run capacitors. The impedance of the auxiliary winding depends on the slip, so a smaller capacitor is needed for optimal running performance. His work has been published in the scientific journal "Physical Review Letters."
