1. Manufacturing of fan motor rotors

The manufacturing of fan motor rotors requires multiple steps, including design, casting, machining and assembly.

1. Design

First, design is required to determine the size, material, shape and other parameters of the rotor. The design must take into account the use and use environment of the fan motor, such as the power, speed, and service life of the fan motor.

2. Casting

Casting is carried out according to the designed rotor drawings and parameters. Casting is the process of pouring metal materials such as aluminum alloy or copper alloy into a mold after melting, and then cooling and forming. During the casting process, parameters such as temperature and pressure need to be controlled to ensure the quality and dimensional accuracy of the rotor.

3. Machining

After casting, machining is required. Machining is the precise processing and grinding of the rotor by CNC machine tools and other equipment. This process needs to take into account the balance and accuracy of the rotor to ensure that the rotor meets the design requirements.

4. Assembly

Finally, the rotor and other motor components need to be assembled. This process requires precise installation to ensure the matching accuracy of the rotor and other motor components, as well as the performance and life of the entire motor.

2. Working principle of fan motor rotor

The fan motor rotor is the core component of the fan motor, and its working principle is based on the principles of electromagnetic induction and electrodynamics.

1. Principle of electromagnetic induction

In the fan motor, the current given by the power supply generates a magnetic field that causes the conductor on the rotor to generate an induced current. Under the action of the magnetic field, the induced current generates electromotive force,

2. Principle of electrodynamics

The magnetic field in the fan motor is generated by the coil on the stator. After the current flows through the stator coil, a magnetic field is generated to attract the conductor on the rotor. While the rotor rotates, the current in the stator coil changes continuously, and the direction and size of the magnetic field also change continuously, causing the conductor on the rotor to be continuously affected by the electromotive force, so that the rotor keeps rotating.

The manufacturing and working principle of the fan motor rotor are the core parts of the fan motor. The manufacturing process requires multiple steps, including design, casting, machining and assembly. During the manufacturing process, it is necessary to take into account the use and use environment of the fan motor to ensure the quality and dimensional accuracy of the rotor. The working principle of the fan motor rotor is based on the principles of electromagnetic induction and electrodynamics. The current given by the power supply generates a magnetic field, which causes the conductor on the rotor to generate an induced current and generate electromotive force.
