Question

How do you calculate the capacitor value for a single-phase motor?

Answer 1

To get the capacitor value for a single-phase motor, we require the following information,

1. The motor's wattage capacity.
2. Voltage.
3. Frequency.
4. Efficiency.

Capacitor value for a single-phase motor

The following equation can be used to determine the capacitor value for a single-phase motor,

$\Rightarrow \mathrm{C}\left(\mathrm{uf}\right)=\frac{\mathrm{p}\times \mathrm{n}\times 1000}{\mathrm{v}\times \mathrm{v}\times \mathrm{f}}$

Where $p=$ power, $n=$ efficiency, $v=$ voltage, and $f=$ frequency.
