Abstract
The magnetic circuit structure and its parameters and magneto motive force of sensor for cable tension are determined by design and analysis of magnetic circuit.Some key issues are discussed on the basis of the structure of difference sensor of cable tension,,such as magnetic circuit structure design and its definition of structure parameters,the selection of magnetic field strength,the definition of magnetic flux and the calculation of magnetomotive force by magnetic circuit analysis.Then the system of experiment is designed,and the experiments of pulling tension are carried on.The experiment results indicate that the magnetic circuit design and the magnetic circuit analysis are feasible,it will open up a new method for the magnetic circuit design.
