摘要：

A novel hybrid excitation guiding device with non-contact and low power loss was proposed. It can be widely used in non-contact guide for elevators and horizontal transport systems. Its operating principle and structure were analyzed to establish the equivalent magnetic model by using equivalent magnetic circuit method. The magnetic flux for each branch was calculated. And then, the analytical expressions of the horizontal magnetic force were derived by using virtual displacement method considering different current and displacement conditions. The structure and electromagnetic parameters were designed aiming at magnetic field and control magnetic needed by maximum magnetic force. The two-dimensional finite element method (FEM) model is established to analyze and compare the relationships between magnetic force and current, as well as magnetic force and displacement. And also the experiment prototype was manufactured. The simulation and experiment results show that mathematical expression of the magnetic force and structural parameters are reasonable. © 2015, The editorial office of Transaction of China Electrotechnical Society.
