The operation principle of the electromagnetism liquid-cooled retarder of a kind of external rotor structure of the present invention is as follows:
During work, by control module to coil power supply, magnetic field can be produced on stator after energising in coil, because coil is directly wound on stator, namely can form toroid.The magnetic line of force can separately arrive on rotor through air gap on stator, because the salient pole of rotor can cutting magnetic induction line, can produce inductive loop like this at stator outer surface, and the magnetic line of force in air gap is perpendicular to the salient pole inner headed face of stator excircle surface and rotor.When truck drive shaft rotates, rotated by rotor arm rotor driven, the magnetic line of force that rotor cutting stator sends, will produce eddy current braking moment at stator outer surface, this braking moment acts on truck drive shaft by rotor arm, namely plays braking action.Control module can change the size of electric current in coil, can realize continuous adjustment to the present invention.The heat that stator produces can be taken away by water channel, and the water in water channel can circulate with the cooling water circulation of engine or with the independent cooling device of retarder, realizes reciprocation cycle work.If when retarder does not need to brake, control module stops coil power supply, at this moment would not produce magnetic field, stator also can not produce eddy current, namely can not produce braking moment.
