Abstract:

A rotor position detection method is studied,which converts rotor position to digital quantity by using resolver-to-digital converter AD2S90.On the basis of the working principles of the rotating transformer,this paper introduces the working principle of the system based on AD2S90,related interface circuit,and detection circuit implementation.The experimental results show that the system design is reasonable and reliable,and the digital position detection circuit composed of rotary transformer and AD2S90 is feasible.
