The comparative analysis of the parameters of electromagnetic transducers of thickness of the winding isolation on the rotating frames

The winding of isolation on the steel and plastic cylindrical frames is applied in the electrotechnical industry. In the topic the control methods and problems for isolation thickness have given. For this purpose, the electromagnetic transducers of the inductive and transformer type displacement have recommended. The principles of operation, physical models and application areas of the transducers have considered in here. The characteristics of the main types of electromagnetic transducers that turn thickness of the wrapping isolation on the cylindrical frames into the electrical quantities have compared and given their advantages and disadvantages.
