Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an armature winding for a commutator motor.

Now, K: number of commutator pieces, S: number of grooves, U: number of coil sides in the upper or lower layer of each groove, T: total number of turns in one groove, Q: number of layers, W: number of turns, n: natural number. , K/S=u=2 The current double flyer winding machine that performs armature winding has one winding number setting dial, so the number of windings on each wire ring side is the same.

Therefore, the total number of windings in one groove is T = u (=2) X Q (=2) XW = 4
W, which is a multiple of 4.

That is, T=4n+2 In this case, it cannot be rolled.

Therefore, the following drawbacks occur.

1. Since T=4n+2 cannot be wound, the space factor decreases accordingly.

2. For example, when W200 = 13 turns in the 200 V specification, in order to have the same characteristics even in the 100 ■ specification, WIOO = 13 x (100/200) = 6.5
In actuality, it will be 6 or 7 turns, and it may be difficult for them to have the same characteristics.

3. Among the two types of coil sides, rectification cannot be improved by reducing the number of turns of the coil with the worse rectification curve.

The purpose of the present invention is to eliminate the drawbacks of the prior art described above.
To provide a winding machine capable of winding armature wire rings with different numbers of turns.

Formula T=uXQXW With u=2 and Q=2, 2W=W+W=W1+(W.+1) If you put T=2X[W. +(W.+1)) =4 WI +2 becomes.

Focusing on the fact that L1=2, that is, by winding one winding W of two types of wire ring sides with an odd number of times and the other with an even number of times, the total number of turns T in one groove can be 4n+2. In this double flyer winding machine, each flyer corresponds to a respective wire ring side, and each flyer is wound independently from each other.

The winding mechanism of the double flyer winding machine according to the present invention was first developed.
As shown in the figure.

A drive unit 5 a that rotates the fryers 3 3 and 3 b
, 5 b, controller 6 that controls it? , 6b, and winding number setting dials 7a, 7b for setting the winding number, and each flyer is independent.

Set the flyer 3a to make a W turn, and the flyer 3b to make a W turn.

First, the L flyer 3a has a W1 turn between the winding pitch (armature groove numbers 12 and 7 in Figure 1), and the R flyer 3b has a winding pitch (armature groove number 1 in Figure 1).
and 6), wind 2 turns of W.

When the winding is finished, the armature shaft 14 is rotated and the armature is moved to the next armature groove.

At this time, similarly, W1 is between the winding pitch (armature groove numbers 1 and 8 in Figure 1) in the L flyer 3a, and W1 is between the winding pitch (armature groove number 2 in Figure 1) in the R flyer 3b.
and 7), wind 2 turns of W.

Similarly, if the armature shaft 14 is sequentially rotated and wound by the number of armature grooves, the total number of turns of all the armature grooves becomes T = 2 W+ + 2 W2.

If the number of turns on one side, for example W1, is an odd number, the number of turns as expressed by the above-mentioned formula T=4n+2 can also be obtained.

Another embodiment is shown in FIG.

This structure is the same as that of the drive unit 8 that rotates the fryers 3 2 and 3 b, the controller 9 that controls it, and the winding number setting dials 10 a and 10 b, but the drive unit and controller are A stand is fine.

Instead, turn W1 on setting dial 10a, 10b
Set it to W2 turn, and make it automatically switch by some kind of signal every takt.

That is, first, set W0 between the winding pitches (armature groove numbers 12 and 7 in Figure 2) on the L flyer, and set the winding pitch between the winding pitches (armature groove numbers 1 and 6 in Figure 2) on the R flyer.
Wrap 1 turn in the same way in between.

When the winding is finished, rotate the armature shaft 14, move to the next armature groove, and at the same time turn the winding number setting dial from 10a to 10b.
Switch to .

At this time, use W2 between the winding pitches (armature groove numbers 1 and 8 in Figure 2) on the L flyer, and W2 between the winding pitches (armature groove numbers 2 and 7 in Figure 2) on the R flyer. Wind W2 turns in the same way.

If you switch the winding number setting dial in the same way,
The number of turns in all armature grooves is 2W. +2W2, and similarly the number of turns T=4n+2 is possible.

According to the present invention, since the space factor within the armature groove can be increased, a motor with low temperature rise can be expected.
