By introducing the angular measuring technology of Inductosyn. The angular measuring principle of amplitude discrimination mode is presented while the inductosyn is working with the bi phase excitation and single phase output . By analyzing the static errors,the model of dynamic errors is established from the amplitude and function errors of double phase voltage,out phase of double phase voltage and waveform distortion.The reasons and effects of dynamic errors are analyzed through detailed calculation.In order to reduce the errors,an effective method has been suggested.
