Unshielded effect, torque are maximum.
Work as electric motor starting, motor driving shaft drives p-m rotor 9 to rotate, and copper conductor cuts p-m rotor 9 in conductor rotor 6
Magnetic induction line in middle permanent magnet, generates induced current on copper conductor, and then forms induced field, induced field and permanent magnet
The magnetic field effect of intercoupling generates torque drive load rotation.
When the magnetic pole of permanent magnet is completely covered in axial shield structure, as shown in figure 4, axial shield structure is axially moveable
P-m rotor is completely covered to left end, since the magnetic conductivity of axial shield structure is nearly thousand times or more of gap location medium,
The magnetic strength line loop of permanent magnet is all limited in axial shield inside configuration at this time, minimum by the line of magnetic induction of copper conductor, copper
Conductor declines with line of magnetic induction dissection, and transmission torque is minimum, loads at this time stationary.
Finally it should be noted that：The foregoing is merely the explanations of the present invention, are not intended to restrict the invention, although to this hair
It is bright to be described in detail, it for those skilled in the art, still can be to aforementioned recorded technical solution
