Counter-rotating Axial Magnetic Field Slotless Permanent Magnet Synchronous Motors Performance Analysis And Simulation

Counter-rotating axial magnetic field slotless permanent magnet synchronous motors(CAMFSPMSM)features:First, a single power port input and two independent different constant velocity, and so the torque mechanical port output structure, the second is a short axial dimensions, light weightsmall size, cogging torque advantage; compared with traditional motors, many scientific problems to be solved, because there is a big difference in the magnetic circuit structure, there are quite a lot of the basic theory of the need to study and verify, this article will focus onclass motor running basic theoretical issues.First, an overview of its operation principle, the for two exclusive coupling characteristics of the rotating magnetic field, to create special equivalent electromagnetic model, isobutyl, thus generated in the stator core caused by the periodic variation of the relative position of the permanent magnet to the rotating axis of the periodic variation to the magnetic circuit, the reluctance parameter variations equivalent changes in the spatial location of permanent magnets the resulting magnetic equivalent circuit model can more accurately reflect the change in magnetic field in the motor. The type of motor is equivalent to two parallel main magnetic circuit, the toroidal winding phase sequence series of permanent magnet synchronous motor, counter-rotating magnetic field in the air gap and rotor permanent magnet-load magnetic field interaction of electromagnetic power; through mechanical the structure and characteristics of electromagnetic relations, the establishment of its model and simulation study.Secondly, affect motor performance parameters for the motor equivalent electromagnetic model through a set of size equation, need to be applied to three-dimensional electromagnetic field numerical methods to accurately analyze the electromagnetic field of the motor due to the special nature of the electromagnetic field distribution, in order to take full account ofsaturation flux scattering and magnetic flux leakage factors. This paper is based on a specific set of size parameters, with dedicated analysis software Matlab and Opera electromagnetic field analysis, co-simulation study of the class of motor performance, and verify the reasonableness of the electromagnetic design methods. Can use the methodology to accurately predict the performance of the motor in the motor design, and can be the basis to optimize the design and improve design efficiency.Finally, on the premise of the basic theoretical research, the development of a16-pole power2.2kW (the uniaxial as a1.1kW) speed500r/min experimental prototype, and the design of the overall project structure, Auto-CAD engineering graphic design software to draw a drawing of motor key parts and components.
