Abstract :
This paper describes the main cause of crosstalk in a cylindrical type rotary transformer by using the electromagnetic field analysis taking account of both the eddy current and the displacement current. Factors affecting the crosstalk of the rotary transformer are also discussed, namely, the permeability and permittivity of core, the conductivity of short-circuited ring and the number of windings per coil
