Mechanism analysis and modeling research of novel hybrid excitation guiding system

The structure of a novel hybrid excitation non-contact and low power consumption guiding system put forward and its operating principle is analyzed. The theory of equivalent magnetic circuit is used for deducing horizontal force. The relation of force, current, and displacement is got. The effect of the magnetic length of PM(permanent magnet) on the magnetic force is analyzed. The design result is carried out by using the finite element methods. A summary of the relationship between the length of PM, electromagnetic potential, displacement and horizontal force is given. Simulation results show that the hybrid excitation guiding system is reasonable.
