Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
First consult shown in Fig. 2, the winding structure of the permanent magnet brush motor for six groove four utmost points of the present utility model comprises 6 winding slots 11, 12 and 6 commutator segments 14 of 2 pairs of magnet steel, in the utility model by the coil on an original winding slot, winding is at 2 winding slots 11 successively: on No. 1 winding slot and No. 4 winding slots, form 2 coils 13, wherein, Line 1 groove is the same with No. 4 winding slots with the geometric relative position of magnet steel 12, all be positioned at N utmost point below, therefore compared with original structure winding, winding ensures to be also the same with the geometric relative position of magnet steel 12 at Line 1 groove with 2 coils 13 on No. 4 winding slots, the like, thereby can make coil 13 inductance reduce to original 1/2nd, the magnetic energy that commutating coil 13 stores is also reduced to original 1/2nd, thereby the situation that makes traditional this method for winding can only apply to low-power machine is improved.
Again in conjunction with shown in Fig. 3, figure comprises 12 and 12 commutator segments 14 of 11,2 pairs of magnet steel of 6 winding slots, traditional six commutator segment electric machine structures of six groove four utmost points, change to now the electric machine structure of 12 commutator segments of six groove four utmost points, after increasing commutator segment, can make short-circuited coil number reduce, increase electric efficiency thereby increase conductor efficiency.By the coil on an original winding slot, winding forms 4 coils 13 at 2 winding slots 11 successively, and concrete method for winding is as follows:
By after the coiling of No. 1 commutator segment to 1 winding slot to No. 4 winding slots continue after coiling (note two grooves institute around active conductor number equal);
To No. 2 commutator segment to 1 winding slot coilings, continue after coiling to No. 4 winding slots;
To No. 3 commutator segment to 2 winding slot coilings, continue after coiling to No. 5 winding slots;
After continuing to wind the line to No. 5 winding slots after winding the line to No. 4 commutator segment to 2 winding slots;
The like last, be back to commutator segment No. 1.
Make compared with original structure winding, winding forms 4 coils 13 at 2 winding slots 11 and ensures to be also the same with the geometric relative position of magnet steel 12, it (is total conductor number of turn that this method for winding can ensure in the situation that other structures are identical, input voltage, rotor falls thick, wire diameter), electric efficiency, torque, electric current, in the situation that rotating speed and conventional motors are consistent substantially, at least can make coil inductance reduce to original 1/8th, the magnetic energy that commutating coil stores is also reduced to original 1/8th.
In above-described embodiment, the intercoil connection of the multiple coils 13 of winding on multiple winding slots 11 is all arranged between winding slot 11 and commutator segment 14, make to wind the line between winding slot 11 and commutator segment 14 overstocked, in the time of actual production, in technique, have problems, so change especially method for winding, as shown in Figure 4, in figure, enumerate the method for winding of single group coil, the other end that is converted to winding slot in Fig. 3 by the intercoil connection 15 of No. 1 winding slot to 4 winding slot, be arranged between winding slot 11 and magnet steel 12, overstocked on the impact bringing in actual production technique to avoid winding the line.
Below embodiment has been described in detail the utility model by reference to the accompanying drawings, and those skilled in the art can make many variations example to the utility model according to the above description.Thereby some details in embodiment should not form restriction of the present utility model, the utility model by the scope defining using appended claims as protection range of the present utility model.
