Analysis of the induced current in the armature of induction type electromagnetic driver

The direction of the induced current in armature will be reversed during the moving. In order to improve the efficiency of the electromagnetic driver, it is better to make the peak point of driving current be ahead of the reverse point. There are two factors to affect the induced current in armature: the variation of the driving current and the movement of armature. It obtains the position relationship between the reverse point of induced current in armature and the peak point of the driving current by analyzing the trend of the induced current under different actions of factors. After all, a simulation model is built to verify the results of analysis. Then it gets the conclusion that the reverse position of induced current is determined by the velocity of the armature, which is useful for the further study of the electromagnetic force for armature and control strategy for electromagnetic driver.
