Choosing Right Capacitor
Choosing the wrong capacitance value for a motor can result in an uneven magnetic field, which can be observed as uneven motor rotation speed, especially under load. This can cause additional noise from the motor, performance drops, and increased energy consumption, as well as additional heating, which can cause the motor to overheat.
- An AC motor uses only a motor start capacitor, which creates a pulsating magnetic field during normal operation.
- Whereas AC motors using a motor start capacitor and a motor run capacitor create a rotating magnetic field during normal operation.
- Motor run capacitors are designed for continuous duty and remain powered whenever the motor is powered.

- MPP Film – Very high-quality MPP film with multilayer metallization – thus the voltage withstanding capacity of the capacitor is more.
- Heavy Edge Film – of zinc provides better bonding between the electrode and the end spray – high current carrying capacity ensures better withstanding of the electromechanical stress caused by switching surges.
- Wires – ISI marked wires used having ends shielded.
- Low Dissipation Factor & Low Loss – Dielectric as Polypropylene – very low dissipation factor with low losses giving longer life to the capacitors.
- Self-healing property – Excellent – Fault due to short circuit results in a small arch which evaporates the metallization in the area of breakdown in microseconds. Thus the reduction of the capacitance is very low due to self-healing and also the capacitors remain in operation.
