Fan motor Silicon steel sheet is an important part of the fan motor, its relevant information is as follows:

effect

Responsible for the magnetic pole export, in order to determine the strength of the magnetic field N, S pole.

structure

It is usually composed of multiple silicon steel sheets stacked together, including silicon steel sheets, insulators and insulating skins. The silicon steel sheets are arranged at parallel intervals, the adjacent sheets are isolated by insulators, and the outer sheets are completely covered by insulating skins.

Common problems and solutions

• Magnetic loss: Direct contact with traditional silicon steel sheet is easy to lead to magnetic loss and poor magnetic circuit, which can be solved by setting an insulator between silicon steel sheets.

• Motor efficiency: The standard material thickness of silicon steel sheet is fixed, which limits the optimal design of motor efficiency. Silicon steel sheet can be used in combination with amorphous nanocrystals to improve efficiency.

Shopping precautions

When buying a fan motor, the thickness of the laminated silicon steel sheet should be as close to or slightly thick as possible with the original motor, otherwise the rear shell of the fan may not go up.
