Problems solved by technology

Since the fixed excitation device is set with a high magnetic permeability material at a certain distance outside the magnetic gap, the magnetic force is proportional to the action area, and the strong magnetic force caused by the excitation increases the magnetic flux of the magnetic gap, so that the excitation device is used in the equipment assembly process. Risk and difficulty, low safety factor in operation, so the structural device used in the magnetic gap excitation is usually strengthened and locked, and there is no fine-tuning function to adjust the magnetic gap distance, which affects the separation effect
