| Abstract: | An universal energy equation of magnetic-force pump coupler was educed by analysis of demagnetization curve and ways of calculating circumferential torque were introduced according to the equation when inside magnet rotor had circumferential moment. Combining the characters of magnetic-force pump magnet steel collocation, appropriate accounting models were selected to calculate magnetic-flux leak coefficient and the magnetic-reluctance coefficient through magnet conductivity methodology. The equations for magnetic-force pump magnet steel axial direction length, circumferential length, and radial thickness were developed after the analyses of the experiment results. |
