1.Working Principle and Classification of Fan
The fan is such a device whose working process is to drive the blades to rotate through the operation of electricity or other energy, hence sucking and discharging air from one area to another area, thus forming a flow of wind. Until now, fans appearing in the market mainly fall into two categories: AC electric fans and DC electric fans.
2. Working Principle and Classification of Relay
Relay is an electrical control device which uses electromagnetic effect to control opening or closing of switch circuits. Its key benefit lies in its capability of successfully controlling the switching over of high voltage or high current circuits from low voltage or low current environment.
3, How to connect the fan and relay together
Confirm the voltage of fan and relay
Before connecting the fan and relay, ensure that their voltages match. This is necessary because inconsistent voltage may cause problems during connection.
Connect the Wires at Both Ends of the Relay
Before wiring the relay with the power supply, make sure both wires are connected to each end of it. The other should be wired to the power supply and the other to the circuit simply for safety and trustworthy connection.
Connect the fan now to the contact of the relay.
Connect the relay contacts with the fan wires tightly and securely, so that the normal operation of the fan will surely be wired up.
Ground Wire Connection
The ground wire has to be connected with the fan and the relay for safety reasons. This is an important part of the connection which cannot be avoided.
Finish Wiring and Check
After all the connections, check all the connections if they are secure, and then test the circuit if it is working well. When fine, smooth start and stop operations of the fan are possible.
4.Summarize
There are basic principles or steps that must be adhered to in connecting a fan and a relay. Among these include the confirmation of voltage, relay wire connections, contacts to a fan, and ground wire connections. Only by adhering to the proper way of connecting the circuit will it work as usual, and proper starting and stopping operations of the fan can be properly executed.
