The 3 groups of magnetic circuits of formation of upper rotor part salient pole 401, compared with the magnetic circuit that existing New Type of Reluctance Machines extends radially through whole motor, the present invention
The magnetic circuit that is formed of New Type of Reluctance Machines be only formed in the second magnetic core, upper stator salient poles 307, upper rotor part salient pole 401 and it
Between magnetic gap in, the length of magnetic circuit greatly shortens, and the formation of originally one winding is a long magnetic circuit, present one around
What group was formed is multiple short magnetic circuits, and multiple magnetic circuits the accumulative cross section increase than an original magnetic circuit of cross-sectional area very
Many, the shortening of the length of magnetic path and the increase of cross section reduce magnetic resistance, so as to improve the efficiency of moment of torsion and motor.This New Magnetic Field Controlled
Resistance motor target be shorten magnetic circuit, therefore upper stator salient poles 307 and upper rotor part salient pole 401 between magnetic gap should as far as possible it is small,
But can not be come in contact between upper stator salient poles 307 and upper rotor part salient pole 401, the rotation of rotor not so can be hindered, therefore
The distance between plane and plane are less than 0.01mm, and they should try one's best in the case where processing conditions allows.
Manufacture and assemble for convenience, two the first adjacent magnetic cores 301 of adjacent two magnetic core groups are connected as a single entity.
During motor operation, upper stator salient poles 307 and upper rotor part salient pole 401 easily become due to being acted on for a long time by magnetic force

Material.Bearing block can use corresponding mould integrated injection molding to stator 2 with the first filling part.
As shown in Figures 6 and 7, present invention also offers a kind of embodiment 2 of New Type of Reluctance Machines, its area with embodiment 1
It is not, in each magnetic core group, the second magnetic core 302 is connected as a single entity with two the first magnetic cores 301.
As shown in figure 8, present invention also offers a kind of embodiment 3 of New Type of Reluctance Machines, the difference of it and embodiment 2 exists
In：The lower surface of first magnetic core 301 has 3 downwardly convex lower stator salient poles, lower stator salient poles and upper stator salient poles 307 1
One correspondence and they width it is equal, the top of all lower stator salient poles at grade, axle of the plane perpendicular to rotating shaft 1
Line；
New Type of Reluctance Machines also includes lower rotor part 6, and lower rotor part 6 is made up of soft magnetic materials, is placed in lower rotor part 6 in lower encioser 7 simultaneously
Fixed thereto, lower rotor part 6 is located at the lower section of stator 2 and coaxial fixed by lower encioser 7 and rotating shaft 1, the upper surface of lower rotor part 6
It is upper with 38 lower rotor part salient poles being evenly distributed, lower rotor part salient pole corresponded with upper rotor part salient pole 401 and they
Radian is equal, lower rotor part salient pole raise up and radially extend, the top of all lower rotor part salient poles at grade, plane
Perpendicular to the axis of rotating shaft 1, the region of the tops of all lower stator salient poles in the plane and the top of all lower rotor part salient poles exist
Region in plane is oppositely arranged in the axial direction；The top of upper stator salient poles 307, the top of lower stator salient poles, upper rotor part salient pole
The 401 top fan ring consistent with the top of lower rotor part salient pole being shapes and sizes, the axis of rotating shaft 1 passes through all fan rings
