Detailed description of the invention
With embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, one fault-tolerant motor topological structure of the present invention, this structure include stator 1, armature spindle 2,
Permanent magnet array, stator 1 include 3N+3 (N=1,2,3 ...) individual winding tooth, on winding tooth be wound around coil around
Group, the winding direction of winding is identical；Armature spindle 2 is positioned at stator 1 either internally or externally；Armature spindle 2 with
Stator 1 is concentric；Permanent magnet array is fixing to be positioned at outside armature spindle 2.
It is uniformly distributed one without winding tooth between the most adjacent two the winding teeth of stator 1.
All being extracted by two binding posts of every phase winding, so every phase winding can use independent driving to open up
Flutterring structure, especially each winding is kept apart by without winding tooth, has physics, heat and magnetic circuit separate
Advantage, uses independent driving and control topological structure at every phase winding, regards an independent passage mutually as,
The advantage not only with electrical isolation, simultaneously mutual redundancy backup between each passage, improve system can
By property, when riches all the way raw fault, fault phase does not interferes with the normal output of other healthy phases
Winding tooth and stacked by silicon steel thin slice without winding tooth and process through electric spark or punch process mode and
Become.
Armature spindle 2 uses non-magnetic material, so can reduce rotor eddy current loss, reduces rotor temperature rise,
It is possible to prevent the generation of permanent magnet demagnetization phenomenon
Tooth without winding both ensure that the physical isolation between winding, and is important flux paths so that respectively around
Group is the most completely isolated on physics, heat and magnetic circuit.
Permanent magnet array includes several magnetic arrays, and each magnetic array includes permanent magnet A6, permanent magnet successively
