| Abstract: | A self-designed 22.5 kW 3-phase pumping permanent magnet motor model using the Halbach structure was established in the method of 2-D finite element analysis.The influences to both no-load and load performance of motor by changing the thickness of permanent magnets as well as width ratio between the radial and tangential magnets used in Halbach structure was analyzed in detail.Indexes such as air-gap induction,back electromotive force,torque pulsation and so on was compared for optimum designing.In this way,the optimum designing project was established. |
