Abstract

The invention relates to a disk rotor motor, which comprises an outer shell, a rotating shaft, a rotor and a stator. The rotor comprises at least a disciform body which is distributed along the axial direction of the rotating shaft; the disciform body is fixed on the rotating shaft and rotates along with the rotating shaft; at least two groups of magnetic poles which are evenly distributed along at least two circumferences with different radius dimensions are arranged on the disciform body; each group of the magnetic poles comprises at least two magnetic poles; the stator comprises a first composite disk component and a second composite disk component which are distributed along the axial direction of the rotating shaft; the first composite disk component and the second composite disk component are fixed on the outer shell; the disciform body of the rotor is positioned between the first composite disk component and the second composite disk component; both the first composite disk component and the second composite disk component comprise excitation coils, at least two groups of iron cores and armature coils which wind on the iron cores, wherein, the iron cores correspond to the two groups of magnetic poles which are evenly distributed along at least two circumferences with different radius dimensions at intervals on the disciform body of the rotor. The disk rotor motor has a close magnetic loop with simple path and lower magnetic loss, and can ensure the high-efficient work of the motor.

Description

technical field [0001] The invention relates to electric machines, especially electric machines with a rotor in the form of a disk. Background technique [0002] Existing motors with disc-shaped rotors have various structures, such as: a disc-type wind power generator disclosed in Chinese patent CN1905331, the stator is composed of winding coils and does not contain ferromagnetic materials; the permanent rotor fixed on the rotor shaft The magnet is a rotating body with the rotor shaft as the axis, and corresponds to the permanent magnets fixed in the upper and lower housings. The polarities of the opposite surfaces are the same, and there is a gap between the two. The generatrix of the rotating body is an arc or broken line or slash; another example: a permanent magnet generator disclosed in Chinese patent CN2901670 includes a housing and a rotating shaft placed on the housing, and the rotating shaft is provided with a magnetic Rotor, the axial sides of the magnetic rotor a...
