Embodiment
Hereinafter with reference to correlative type, a kind of motor according to preferred embodiment of the present invention is described, wherein identical assembly will be illustrated with identical reference marks.Notice, structure shown in this Figure of description, ratio, size etc., equal contents in order to cooperate specification to disclose only, understand and reading for those of ordinary skill in the art, be not to limit the enforceable qualifications of the present invention, so technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, not affecting under the effect that the present invention can produce and the purpose that can reach, all should still drop on disclosed technology contents and get in the scope that can contain.
Please be simultaneously with reference to Figure 1 and Figure 2, wherein Fig. 1 is the schematic diagram of a kind of motor of preferred embodiment of the present invention, Fig. 2 is the vertical view of silicon steel structure of the motor of Fig. 1.Motor 1 of the present invention can be a single-phase motor.In addition, motor 1 can be an external-rotor motor or is an inner rotor motor.At this, illustrate that as an example of an external-rotor motor example so not as example, in other example, motor also can be an inner rotor motor.In addition, the present invention does not limit the face shaping of motor 1 yet, and along with the difference in application function or field, motor 1 also can structurally change.Wherein, motor 1 comprises a silicon steel structure 2 and coiling L.
Please refer to shown in Figure 3ly, it is set around the schematic diagram of silicon steel structure for single coiling of the present invention.Wherein, arrow represents the sense of current, also represents direction of winding.Coiling L is enamelled wire, it sequentially is set around winding section 211a, the 211b of the first double wedge 21a and the second double wedge 21b with a first direction and a second direction, then sequentially be set around again winding section 211c, the 211d of the 3rd double wedge 21c and the 4th double wedge 21d with second direction and first direction, T1 and T2 are the tie lines point, and reach the effect that is connected in parallel around mode in positive and negative minute with single line.The first direction of present embodiment is example in a clockwise direction, and second direction is non-in order to limit the present invention take counterclockwise as example, and in other embodiments, first direction can be counterclockwise, and second direction can be clockwise direction.
In more detail, coiling L is set around the winding section 211a of one first double wedge 21a with first direction (clockwise direction), is set around the winding section 211b of the second double wedge 21b with second direction (counterclockwise) again.The L that then winds the line is set around the winding section 211c of the 3rd double wedge 21c with second direction (counterclockwise), is set around at last the winding section 211d of the 4th double wedge 21d with first direction (clockwise direction).
