Stationary magnetic field to the first rotor 3 generate braking moment, therefore can enable the first rotor 3 slow down.Braking winding 2 makes the first rotor 3
When deceleration, generation heat is less, and electric motor overheating will not be made serious, effectively extension motor life.Using braking winding 2 come
When braking the first rotor 3, since the Working winding 31 of the first rotor 3 still alives, the air-gap field of the second rotor 4 is dragged
The difference of the mechanical separator speed of synchronous rotational speed and the first rotor 3 itself that revolving speed generates for the Working winding 31 of the first rotor 3, first turn
The revolving speed of son 3 is controlled by the braking moment size of braking winding 2, therefore changes the big of the DC current being passed through to braking winding 2
It is small, the revolving speed of the air-gap field between the first rotor 3 and the second rotor 4 is also just changed, to change turning for the second rotor 4
Speed.User can be passed through the size of the DC current of braking winding 2 by control to control the revolving speed of the second rotor 4.Second
