Abstract
A nondestructive testing sensor for magnetization curve of electrical steel sheet is studied
magnetic flux and magnetic potential in a particular area of steel are measured by magnetic flux measurement coil and magnetic potentiometer in the sensor to achieve nondestructive testing of magnetization curve of the steel. 2D and 3D simulation experiments of the sensor are carried out through ANSYS software
the sensor is optimally designed.Meanwhile
the measured value of magnetic flux measurement coil and magnetic potentiometer under different excitation loads are calculated by simulation experiments; basic magnetization curve of electrical steel sheet is obtained by curve fitting method for the detected signal. The simulation experiments verify the correctness of the sensor detection scheme and the feasibility of the optimization design
