Method for determining two pseudo-sinusoidal signals in quadrature

摘要

A method for determining two pseudo-sinusoidal signals in quadrature from a pseudo-sinusoidal signal transmitted by an encoder is provided. The method using a sensor arranged within reading distance of the encoder, which sensor includes at least four sensing elements which are linearly equally distributed. The sensing elements are each capable of delivering a signal S_i representative of the signal transmitted by the encoder. The method measuring the signals S_i and combining the signals S_i in order to form the signals U=(S_i-S₂)-(S₃-S₄) and V=(S₂-S₃), which signals U and V are in quadrature. A system for determining by implementing such a method, as well as a bearing including such a determination system, are provided.
