In order to solve the problem of immeasurability of eddy current density on the conductor plate and magnetic field intensity in the air gap, this paper establishes the eddy current soft measurement model. Eddy current density of the PM eddycurrent driver during run time can be calculated by measured data of slip speed and air gap in this model which is based on equivalent magnetic circuit. Then, the calculation formula of the torque can be deduced by applying this model. Transmit performance which provides an important basis for optimization calculation and preliminary design is also analyzed. All calculated soft measurement results are compared with results of finite element method using ANSYS software and experimental data. FEM results and experiment results confirm the validity of the soft measurement mechanism model. [ABSTRACT FROM AUTHOR] |
