| Popis: | 105 The magnetic and electric interaction between the magnetic force of permanent magnet and conductor plate is utilized in permanent magnet Eddy current coupling for contactless rotating speed and torque delivery between two rotation axes. Under moving conditions, this study aims to solve the problems of magnetic field on 3-disk permanent magnet Eddy current coupling and Eddy current and torque caused by the mutual movement and to establish a systematic mathematical model. The model is first presented the magnetic vector potential distribution of permanent magnet with Fourier series. Magnetic vector potential Laplace equation is then used for presenting the basic general solution of magnetic field. The magnetic field equation under each boundary condition is established according to the general solution. The unknown coefficients in the magnetic field equation under boundary conditions are calculated with simultaneous operation to deduce different characteristics of turning moment and magnetic flux density under distinct conditions. Finite Element Analysis is further applied to verify the accuracy. A new-style adjustable speed mechanism for 3-disk permanent magnet Eddy current coupling is also designed and produced to improve the shortcomings of commercial products as well as to break through current patents. |
