Fun 3 Speed Motor Connection

A three phase motor must be wired based on the diagram on the faceplate.

3 speed motor connection. The motor will also have three speed wires and one neutral wire. A three speed motor usually has four wires the three speed wires and the common wire. Nowadays this motor is used in most coolers.

And the remaining two stars are drawn in it one is red and the other is black the red wire comes out of the running winding and the black wire comes out of the starting winding of the motors. Each field winding is designed to spin the rotor at a different speed. That being said there is a wide range of different motors and what you have on hand can be completely different.

In a three wire motor the blue wire is made common wire which is connected to the neutral wire of 220 volt power supply coming from the rear. Many motors today are designed to be as flexible as possible when it comes to speed. Using the fan manufacturer s wiring diagrams as a guide locate the wires for the three speed switch and the fan s motor.

Power is supplied to the common wire and any one of the speed wires for a certain speed. Coolers are used mostly in the summer season in different countries nowadays many company coolers are going some coolers and remote controlled coolers are also available in the market. A three speed motor has three field windings and a rotor all in one housing.

The first step is to figure out the voltage of your phases. Cooler motor winding is very easy in this post we have told how you can wind a 24 slot cooler motor in 3 speed. This enables one motor to be used for a number of different applications.

The switch will have a single main input wire known as the line and three additional wires that control speed. In this video we explain three speed cooler motor or multi speed cooler motor with regulator switch in three speed cooler motor we have 3 speed wire and one.
