Warm tip: product size are manual measurement, there will be some error, mind not to shoot!

Why not with a plug

① The product is not equipped with a plug because the starting current is large when the product is turned on, and the power cord needs to be installed on the air switch to protect the fan.
② The fixed type is generally a single-sided net cover. If you need a double-sided net cover, contact customer service and add the net cover fee.

The principle of the motor is based on Faraday's law of electromagnetic induction. When a conductor moves in a magnetic field, an induced electromotive force is generated in the conductor. In a motor, this magnetic field is generated by the passage of current through a coil. When the current through the coil, the coil will produce magnetic induction intensity, the magnetic induction intensity is proportional to the size of the current. According to Ampere's law, the magnetic induction intensity is proportional to the magnetic flux density around the wire.

According to this principle, the motor can be divided into two types: DC motor and AC motor. The DC motor is powered by a DC power supply, and the magnetic field generated is also a DC magnetic field. The AC motor is powered by an AC power supply, and the magnetic field generated is alternating. According to the structure and working principle of the motor, it can also be divided into synchronous motors, asynchronous motors, stepping motors and other types.

The working process of the motor can be briefly described as: When current is passed through the coil, a magnetic field is generated in the coil. If a magnet is placed in this magnetic field, the magnet will move under the action of force. This movement is related to the direction and magnitude of the current, and the position of the coil and magnet. By controlling the direction and magnitude of the current, the movement mode and speed of the motor can be controlled.

The application of motor is very extensive, covering almost all fields. In industrial production, motors are used to drive various mechanical equipment, such as conveyor belts, pumps, fans, compressors, etc. In family life, motors are used for power tools, home appliances, such as washing machines, televisions, air conditioners, etc. In transportation, motors are used in electric vehicles, electric bicycles, etc. In the field of aerospace, motors are also an indispensable part.

With the development of science and technology, the performance of the motor is also constantly improving. Today's motor has the characteristics of * *, low noise, energy saving and so on. At the same time, the degree of automation of the motor is getting higher and higher, and precise motion control can be achieved through computer control.

In short, as a device that converts electrical energy into mechanical energy, the motor is widely used in various fields. With the continuous advancement of technology, the performance and application of the motor will continue to expand.
