Abstract :
Air-gap magnetic field of electromagnetic continuously variable transmission (EMCVT) is composed by permanent magnet and electromagnetic excitation winding. FEM is adopted to study the three-dimensional airgap magnetic field based on mathematical model. The trust deduced of air-gap magnetic field from FEM is verifield been adjusted by the theoretic prototype. The study shows the magnetic field of EMCVT is high and flexible. The hybrid excitation EMCVT has advantages of permanent magnet electromotor and electromagnetic excitation electromotor, and overcome the shortcoming of them.
