Electromagnetic Properties Analysis of Field-Modulated Asynchronous Magnetic Couplings

Abstract:

In order to research the working status of the field-modulated asynchronous magnetic coupling under loading condition, the electromagnetism characteristics such as the distributions of induced current, torque and loss were obtained by using the ANSOFT software to carry on the transient analysis. The results show that the induced current in the whole of magnetic coupling is not evenly distributed. The induced current of copper is maximum, followed by the ferromagnetic pole-pieces. The highest induced current density is in the outside boundary of the copper layer so that the skin effect of current is verified. The current density and loss increases with increasing of the workload, while the torque increases firstly and then decreases with increasing of the workload. When the slip ratio exceeds 12%, the coupling appear skid phenomenon because the loads is greater than the maximum load which the coupling can bear.
