(Wounding method)
Hereinafter, a method of winding the wire rod W for manufacturing the multi-pole armature by winding the winding around the multi-pole armature pole portion a of the multi-pole armature C using the winding machine M will be described.

First, in step S1, as shown in FIG. 3A, the multi-pole armature C is set on the indexing rotation shaft 41 of the multi-pole armature holding device 4, and the start switch (not shown) of the control device is set. When operated, the multi-pole armature holding cylinder 42 lowers, presses and fixes the multi-pole armature C, and winds the multi-pole armature electrode portion a by the multi-pole armature indexing motor 40. 2 Place on the flyer 20 side. At this time, the winding head 6 is retracted so as to be located outside the second flyer 20, and the nozzle 23 of the second flyer 20 is arranged at a position facing the terminal of the multipole armature C. .. Further, one end of the wire rod W is held by a wire clamp device (not shown).

As shown in FIG. 3B, in the following step S2, the second flyer feed motor 22 advances the second flyer 20 toward the multi-pole armature C, and the second flyer vertical motor 30 advances the multi-pole armature. The second flyer 20 is positioned in the vertical direction with respect to the child C, and moves to a locking position for locking the wire rod W to the terminal t.

In step S3, the second flyer rotation motor 21 and the second flyer feed motor 22 cooperate with each other to drive the wire rod W to be locked to the winding holding portion ta of the terminal t as the start wire W (S). , Perform terminal line processing.

In step S4, as shown in FIG. 4C, the second flyer feed motor 22 and the second flyer up / down motor 30 are operated to position the second flyer 20 with respect to the center of the multipole armature C. ..

The wire rod W can be wound in a plurality of layers by reciprocating the main former 60 a plurality of times by the first flyer feed motor 12. Here, it is also possible to adopt a configuration in which the second flyer 20 is not retracted (or advanced).

When the winding with respect to the first multi-pole armature portion a is completed, the first flyer feed motor 12 operates, and the main former 60 retracts from the multi-pole armature C.

As a result, the first phase of the motor is formed.

In step S10, steps S3-S9 are repeated a predetermined number of times (for example, in the case of a three-phase motor, three times corresponding to the three phases of U phase, V phase, and W phase), and winding to the multipole armature C. Is completed.

For example, in order to perform winding as shown in FIG. 1, first, the start wire W (S) is locked to the terminal t (W-U), and then the U-phase winding is performed in the order of U1 → U2 → U3 → U4. Make a line. Subsequently, the tap wire W (T) is locked to the terminal t (UV), and the V phase winding is performed in the order of V1 → V2 → V3 → V4. Then, the tap wire W (T) is locked to the terminal t (V-W), the W phase winding is performed in the order of W1 → W2 → W3 → W4, and the finish wire W (W) is wound on the terminal t (WU). F) is locked to end the winding.

In step S11, as shown in FIG. 5 (F), the second flyer feed motor 22 and the second flyer up / down motor 30 operate, the second flyer 20 retracts, and the multi-pole armature presser foot is pressed. The cylinder 42 is raised, and the multi-pole armature C is taken out from the winding machine M as a multi-pole armature.

In these large motors, a thick wire is used as the wire rod W. Here, the thick wire can be exemplified as a typical wire diameter having a nominal conductor diameter of about 0.5-3.0 mm. Further, the terminal shape can be exemplified as a plate shape having a thickness of t0.4-1.0 mm.

FIG. 6 shows an example of changing the terminal line processing. In this modified example, the winding holding portion that locks and holds the wire rod W is provided at the tip end portion of the multi-pole armature holding cylinder 42 of the multi-pole armature holding device 4.
