| Abstract: | The equivalent magnetic circuit of twin-type relay was built respectively in three typical structures.Through the subsection process of BH curve,the electromagnetic interference torque between two relays was quantitatively calculated.The simulation results obtained by 3-D finite element method agree well with the theoretical calculation,which shows validity of the magnetic circuit model.The analysis is valuable for the design of twin-type relay. |
