Four four-wheel-driven brushless non-hub motors are adopted as power of four wheels for overcoming the defects that the turning diameter of an electric vehicle is large. When the electric vehicle turns towards the left, the two left wheels turn inversely, the two right wheels turn forwards, and the four wheels simultaneously rotate at the same speed forwards and inversely; when the electric vehicle turns in 180 degrees, the turning diameter is zero. Through the method that a controller changes the phase positions of the non-hub motors and changes working points of Hall lines, inverse rotating is achieved, and the speed of inverse rotating is equal to that of forward rotating.
