Numerical computation is processed for the analysis of large gap magnetic drive system driven by traveling wave magnetic field, and magnetic field analysis function of ANSYS software is used as the finite element analysis. Simulating is conducted to get the relationship between permanent magnet’s angular displacement and electrifying state of electromagnet coil. The rules of how main system parameter affect system’s driving characteristic are studied. The simulation is validated by experimental result: Torque capacity of the system can be improved by increasing the number of windings of coil, the electric current of coil, the outside diameter of permanent magnet, the magnetization of permanent magnet, or reducing the coupling distance between electromagnet and permanent magnet. Torque capacity of the system can also be improved by placing the position of electromagnet and permanent magnet in 5mm-10mm relative position in y direction (at both the left and right side).
