いものであつた。 A capacitor is used to eliminate sparks between the commutator and the brushes in a commutator motor. Conventionally, a capacitor 2 is fixed on a ground plate 1 as shown in FIG. Generally, the lead wire 2a is connected to the ground plate 1, and the other lead wire 2b is connected to each commutator piece, and since adhesive is used to fix the capacitor to the rotor, it is difficult during manufacturing. An adhesion process was required. Furthermore, if the capacitor is fixed only with adhesive, the position of the capacitor cannot be determined, which causes an increase in the unbalance of the rotor.Furthermore, this configuration has the problem of increasing the axial dimension of the motor. There has also been a proposal that uses a ring-shaped support plate and places a capacitor inside the support plate so that the support plate receives the centrifugal force during rotation, but it is not fixed in the direction of rotation. Fixation was unstable and problems such as rotor imbalance were likely to occur.

The present invention provides a capacitor mounting device for a motor that protrudes more, eliminates the need for adhesion during assembly, and can reliably support the capacitor.

ある。 An embodiment in which the present invention is applied to a three-pole motor will be described below with reference to the drawings. Figure 1 shows a capacitor block, in which 11 is a support ring formed by punching out a conductive material such as a brass plate, 12,
Reference numeral 13 denotes a capacitor stopper piece that is integrally formed on the inner edge of the support ring 11 and bent at right angles to stand upright.The stopper pieces 12 and 13 are provided at intervals along the circumferential direction of the capacitor. Also, one holding piece 12 is long and the other stopper piece 13 is short so that they do not overlap when unfolded during punching, and the long stopper piece 12 is selected to be longer than the entire length of the capacitor 2. be. The capacitor 2 has a cylindrical shape with two lead wires 2a and 2b provided on one bottom surface, and stopper pieces 12 and 1 are used.
3 and the inner wall 11a of the ring between the stopper pieces 12 and 13, with the circumferential surface of the capacitor 2 in contact with the support ring 11, connect one lead wire 2a to the support ring 11 by soldering or spot welding. It has been done.

のである。 Fig. 2 shows a rotor with a capacitor block installed. 14 is a rotating shaft, 15 is an iron core, 16 is a coil, 17 is a commutator, 18 is a commutator piece, and 19 is a rotor around which the coil 16 is wound. The capacitor blog is a slot formed between each magnetic pole of the iron core 15.
9, and the capacitor 2
The other lead wires 2b are connected to the corresponding commutator pieces 18, respectively. The mounting position of each capacitor 2 with respect to the support ring 11 is regulated by stopper pieces 12 and 13, and the stopper pieces 12 and 13 are arranged on the iron core by appropriately selecting the dimensions.
Since it also acts as a positioner when combined with capacitor 5, it becomes easy to fix the capacitor 2 in the correct position, and the occurrence of unbalance is reduced.
Furthermore, if the stopper piece 12 is made larger than the thickness of the iron core 15, the capacitor block can be more securely fixed by bending the stopper piece 12. Further, each capacitor 2 is held between two corresponding stopper pieces 12 and 13, and at this time, the circumferential surface of the capacitor 2 and both stopper pieces 12 and 13 are held.
If the central angle at the center of the capacitor 2 between both contact points with the capacitor 2 is approximately 90 degrees, the capacitor 2 will exert a reliable holding force in both the radial direction and the circumferential direction of the capacitor 2. It is possible to do so.

発揮することができるという利点がある。 As described above, in the present invention, the two stopper pieces that come into contact with two circumferentially spaced points on the circumferential surface of each capacitor protrude from the inner edge of the support ring, so that the capacitor can move in the direction of centrifugal force. Since the capacitor is held in any direction of rotation, the capacitor is held more securely, and the capacitor mounting device is also accurate, so it does not cause unbalance of the rotor, and a rotor with small unbalance can be obtained. In addition, since the capacitor is securely held, there is no need for gluing, making the assembly process easier, and the length of the motor in the axial direction can be made smaller than when using a ground plate as shown in Figure 3. There are advantages such as being able to In addition, if the center angle between the contact points between the two stopper pieces and the capacitor is approximately 90 degrees with respect to the center of the capacitor, it will exert a large holding force in both the radial and circumferential directions of the circumferential surface of the capacitor. It has the advantage of being able to
