Technical scheme：To achieve the above object, the present invention adopts the following technical scheme that：
It is a kind of without magnetic brushless electric machine, including motor housing, rotor and stator, described rotor be superimposed by rotor punching and
Into described stator is formed by stacking by stator punching, and described rotor punching is disposed with axis hole, rotor triangle from inside to outside
Hole and slotted eye, the groove of domatic being additionally provided with axis hole, described stator punching encloses from inside to outside is disposed with rotor hole, around
Wire casing, stator delthyrium and cramp groove.
Further, described rotor delthyrium surrounds the rounded arrangement of axis hole, and each hole interlocks between sharing two groups, two groups
Arrangement, every group of quantity are 34.
Further, described slotted eye is the larger one section of less oval structures in one end, rounded around rotor delthyrium
Arrangement, quantity are 34.
Further, described coiling trench bottom is circle, and opening two is not provided with buffering tooth, and winding slot, which is arranged on, to be turned
Sub-aperture outer ring, quantity are 24.
Further, described stator delthyrium surrounds the rounded arrangement of winding slot, and each hole is handed between sharing two groups, two groups
Mistake arrangement, every group of quantity are 24.
Further, described cramp groove is arranged on stator punching outer ring, is waveform, and quantity is 6.
Beneficial effect：The invention provides one kind without magnetic brushless electric machine, suitable for all kinds of electric cars and the " height of electric automobile
Energy-saving electric vehicle and novel automobile motor are imitated, the change of the core groove profile shape of motor, so that this motor has effect
Rate is high, and moment of torsion is big, and electric current is low, and temperature rise is low, and noise is low, and stability is high, and manufacturing process is simple, cost is low, etc. advantage.
