Air conditioners and electric fans are both cool appliances in summer, but they have their own pros and cons! The biggest advantage of an electric fan compared to an air conditioner is that it saves electricity! For these two kinds of electrical appliances, if the one-year use period is the standard, the electric wall fan saves much more electricity than the air conditioner! At the same time, the wall fan imitates the natural wind, and it won't be uncomfortable when it blows on people, which is suitable for people of all ages. As the core component of the fan, It is of great importance to choose a suitable wall fan motor.
Here is the content list:
What is the working principle of a wall fan motor?
Are the wall fan motors the same size?
How to choose wall fan motors of suitable model and good quality?
Wall fan motors usually use AC motors. Its working principle is: the energized coil rotates under force in a magnetic field. Electric energy is converted into mechanical energy, and at the same time, due to the resistance of the coil, it is inevitable that a part of the electric energy will be converted into heat energy. In addition, low-power motors such as DC motors and DC brushless motors are increasingly used in small electric fans. When the electric wall fan motor is working (assuming that there is no heat transfer between the room and the outside world), the indoor temperature not only does not decrease but increases. Let's analyze the reason for the temperature rise: When the wall fan motor is working, because there is currently passing through the coil of the electric fan, the wire has resistance, so it will inevitably generate heat and release heat outward, and the temperature will naturally rise. But why do people feel cool? Because there is a lot of sweat on the body surface of the human body when the wall fan motor works, the indoor air will flow, so it can promote the rapid evaporation of sweat, combined with evaporation needs to absorb a lot of heat, So people will feel cool.
The diameter of the blade of the wall fan motor is different, and the power of the AC motor is different. Of course, the installation size and shaft extension will also be different. There are 18-inch and 16-inch wall fan motor (fan blade diameter), and the wall fan motors of the same fan blade size are basically universal.
You can observe with eyes from the surface to see if the color of the coil at the AC motor vent is burnt. If there are traces of burning, it means that the AC motor coil is burnt and cannot be used as shown in the figure below. You can only replace the AC motor with a new one; Check whether the connecting wires are connected properly and whether there is a virtual connection. If the external connection line has a virtual connection, it should be connected in time and insulated; it depends on the appearance of the dirt to determine how long it has not been oiled and maintenance. If it has not been oiled for a long time, perform maintenance A maintenance treatment includes cleaning the internal shaft and tile; see whether the surface of the capacitor connected to the wall fan motor is deformed, etc. If there is deformation, it means that the capacitor is damaged and needs to be replaced with a new capacitor.
It is the responsibility of each manufacturer to produce wall fan motors that meet the standards, so as to ensure the safety of the electricity supply. Fan motor Co., Ltd. conducts many tests on durable wall fan motors before they leave the factory, and the quality qualification rate is guaranteed. If you are in the wall fan motor business, you can consider our cost-effective products.
