When additive excitation coil switch J1 closes, current path is V power supply 1-resistance R1-inductance L 1-switch J1-power supply V1, because of the just very high potential of the first diode D1 and the 3rd diode D3, the negative pole of the second diode D2 and the 4th diode D4 is low potential, so all diodes are reverse blocking state, electric current can not flow through from diode.Also namely electric current is the input inflow of electric current from the lower end 31 of the upper end 30 of the lower end 27 of lower additive excitation coil 23, middle additive excitation coil 22, upper additive excitation coil 20, flow out from the upper end 32 of the lower end 29 of the upper end 28 of lower additive excitation coil 23, middle additive excitation coil 22, upper additive excitation coil 20, according to right-hand rule, the upper end of upper additive excitation coil 20 is the arctic, lower end is the South Pole, the arctic with the upper end of upper magnetic ring 8, lower end is that the South Pole is identical, plays the effect strengthening upper magnetic ring 8 magnetic field; The upper end of middle additive excitation coil 22 is the South Pole, and lower end is the arctic, is the South Pole with the upper end of middle magnetic ring 9, and lower end is that the arctic is identical, plays the effect strengthening middle magnetic ring 9 magnetic field; The upper end of lower additive excitation coil is the arctic, and lower end is the South Pole, is the arctic with the upper end of lower magnet ring 10, and lower end is that the South Pole is identical, plays the effect strengthening lower magnet ring 10 magnetic field.After additive excitation coil electricity, powerful magnetic field force remains between upper magnetic ring 8 and lower magnet ring 10 by transmission main shaft 16 and middle magnetic ring 9 and moves, can transmit by magnetic force the axial force that transmission main shaft is subject to, avoid motor bearings and directly bear axial force.
When switch J1 disconnects, power supply V1 cannot form loop, there is no current flowing, but the magnetic field energy in inductance L 1 needs energy discharge paths, the positive pole of the second diode D2 and the 4th diode D4 is high potential, the negative pole of the first diode D1 and the 3rd diode D3 is low potential, diode is forward conduction state, electric current flows through from diode, and get back in additive excitation coil, form afterflow, and the resistance R1 relying on additive excitation coil intrinsic is to consume energy storage, so the punch-through that there will not be overvoltage to cause.
