As shown in Figs. 1-2, a kind of hollow-cup motor, including shell 1, stator 2, magnet ring 3, coil 4, bearing 5, shaft 6, turn
Subrack 7 and end cap 8 are equipped with brush 81 on the inside of end cap 8, and rotor rack 7 and shaft 6 are coaxially disposed, and 4 one end of coil, which is arranged to be fixed on, to be turned
In subrack 7, array is equipped with multiple welding holes 72 on the rotor rack 7, and the quantity of welding hole 72 and the number of poles of coil are identical, we
Case is 7 extremely examples with the number of poles of coil, so, the quantity of welding hole 72 is 7, and changing for array setting is additionally provided in rotor rack 7
To piece 71, the quantity of commutator segment 71 is identical as welding hole 72, and commutator segment 71 is L-shaped, one end and setting in 6 periphery of shaft,
The other end is vertical with shaft 6, is extended in welding hole 72 in the radial direction in rotor rack 7, and the middle pumping and commutator segment 71 of coil 4 exist
Welding connection, is located at pad in welding hole 72 in welding hole 72, prevents pad from occupying the inner space of motor, makes motor
Volume it is smaller, moreover, in order to prevent in take out with commutator segment 71 conduction it is bad, can welding hole 72 use more scolding tin into
Row welding, since the size of pad does not influence the volume of motor, makes coil 4 after welding hole 72 is arranged by test
It is middle take out it is more preferable with the conductive effect of commutator segment 71, between multiple polarity conduction more balance, reduce coil 4 because conduction not
It generates heat caused by balance.
As shown in Figure 3-4, this programme further embodiment, coil 4 are drum-shaped, and each winding is made of multi-turn copper wire,
Every circle copper wire winding is divided into positioned at the inside of drum-shaped 41 and the outside 42 for being located at drum-shaped, and inside 41 and outside 42 are symmetrical junction
The outside 42 of structure, the coil 4 can be V-type or W type, by taking Fig. 4 as an example, when outside 42 is V-type, and the complete shape of one circle
For diamond shape, this set method can preferably arrange winding, keep each coils arrangement neat, the electromotive force generated and magnetic field
More uniform, the electric current between each winding also more balances.
As seen in figs. 5-6, in order to make the welding between commutator segment 72 and the middle pumping (connector of i.e. each winding) of coil 4
More efficient, welding quality is more preferable, welding when use stationary fixture 9, stationary fixture 9 include fixed frame 91, cylinder 92 and in
It takes out fixed link 93 to form, cylinder 92 is vertically fixed on fixed frame 91, and output end is equipped with press ball 921, middle pumping fixed link 93
Quantity it is identical as the quantity of welding hole 72, middle pumping fixed link 93 by body cradle (not identifying) be arranged on fixed frame 91, in
It is hinged by hinge joint 932 to take out fixed link 93 and body cradle, middle 93 upper end of pumping fixed link is equipped with corresponding convex with press ball 921
Block 931, middle 93 array manner of pumping fixed link are hinged on body cradle, in use, middle 93 lower end of pumping fixed link correspondence is reached
In middle pumping, i.e., middle pumping is covered in middle 93 lower end of pumping fixed link, when cylinder 92 moves downward, press ball 921 presses convex block 931, makes
The middle lower end for taking out fixed link 93 is that fulcrum is mobile to 6 center of shaft with hinge joint 932, and middle pull is tight, make in be pumped through welding
Hole 72 is located at right above commutator segment 71, and when being welded, middle pumping will not be moved, and not only welding effect is more preferable, and welds effect
Rate is higher, originally welds a motor and needs using 85 seconds, is 34 seconds the use of the one motor time of the welding of stationary fixture 9 now,
Welding efficiency greatly improves.The operating pressure of cylinder 92 is adjusted, the lower pressure of the cylinder 92 of available needs prevents cylinder 92
Pressure excessive middle pumping is caused to damage.
It is additionally provided with spring 934 in middle 93 lower end of pumping fixed link, so that middle pumping fixed link is divided into two sections, the both ends point of spring 934
It is not set between two sections, makes middle 93 elastic construction of pumping fixed link, the reason is that, during using machine coiling 4, in
The length of pumping generally will not be identical, and the length of middle pumping and unstable, and spring 934 can draw the middle pumping of different length respectively
Tightly.
