Wiring Diagram AC Fan Motor

An AC fan motor is a type of electric motor that is used to power a fan. It is typically used in air conditioners, heaters, and other appliances that require a fan. AC fan motors are typically rated in amps and horsepower. The amp rating of a motor tells you how much current it will draw from the power source, and the horsepower rating tells you how much power it can produce.

AC fan motors are typically wired in a series circuit with a capacitor. The capacitor helps to start the motor by providing a surge of current. The capacitor is typically connected in parallel with the start winding of the motor. The start winding is a high-resistance winding that is only used when the motor is starting. Once the motor is up to speed, the start winding is disconnected from the circuit.

The following is a wiring diagram for a simple AC fan motor:

In this diagram, the black wire is the power wire, the red wire is the start winding, the blue wire is the run winding, and the green wire is the capacitor. The power wire is connected to the L terminal of the motor, and the start winding is connected to the S terminal. The run winding is connected to the T terminal. The capacitor is connected between the S and T terminals.

When the power is turned on, the current flows through the power wire, the start winding, and the capacitor. The capacitor provides a surge of current to the start winding, which helps to start the motor. Once the motor is up to speed, the start winding is disconnected from the circuit. The current then flows through the run winding, which powers the motor.

AC fan motors are relatively simple devices, but they are an essential part of many appliances. By understanding how they work, you can troubleshoot problems and keep your appliances running smoothly.
