couplings;  magnetic circuits;  magnetic conductivity;  Magnetic leakage coefficient

Magnetic coupling is a new type of non-contact power transmission equipment developed in recent years, which requires stable and reliable work, economic and durable, and also requires high power transmission efficiency and low energy loss. The magnetic circuit was optimized, a cylindrical push-pull coupling system was selected, the appropriate size was determined, and the magnetic permeability and flux leakage coefficient were calculated. The calculation results show that the magnetic circuit design is reasonable, and the requirements of small magnetic resistance and minimal magnetic leakage can be achieved.
