を提供することを目的とするものである。The figure A shows a plan view, and the figure shown above shows a cross-sectional view. In the figure, 8' is a rotating shaft, and a flat commutator is provided for this rotating shaft, and a coil is formed around the outer periphery of this commutator. In the figure, 5' indicates a commutator segment, and 9' indicates a coil. Each coil has a winding start and a winding end, and for adjacent coils, the winding start a' of one coil is connected to the winding end a' of the adjacent coil, and this Therefore, since both connecting wires pass above the coil 9' and reach the adjacent coil 9', a portion of the connecting wires inevitably overlaps with the upper part of the coil. In the case of such a structure, if the coil is a self-fusing type, the coil may be pressed and shaped, or the coil and commutator segment,
When a rotary shaft or the like is integrally molded, there is a risk that the connecting wire and the coil may be short-circuited due to the pressure applied during shaping or molding. The present invention improves the above-mentioned drawbacks, and provides a rotor for a flat plate motor that is easy to manufacture and can prevent the winding start end from overlapping the wound coil portion when manufacturing the rotor. The purpose is to

have. The segment tip 5a has an arc-shaped outer side between the tip and the arm 5b15b'. This is to prevent scratches on the outer periphery of the rotor when the rotor coil is wound as will be described later. Now, the aforementioned arm portions 5b15b' are each bent at approximately the center portion (point c), and the tip portion from the center portion is bent in a direction perpendicular to the plane of the paper to form a bent portion 5c (second (See Figure I).
Since the arm portions 5b15b' of adjacent segments are similarly bent to form bent portions, the coil support 6 made of an insulator is fixed between the bent portions 5c of the adjacent segments. This state is shown in Figure 2, A and C. In FIG. 2, A shows a plan view, the mouth and C show a side view. Next, a coil is wound around this coil support.

When forming a coil around the coil support piece 6 using a self-fusion wire, the winding start of the coil is connected and fixed to the bent part a of the commutator segment on one side of the coil support piece 6, and the coil is connected to the bending part a of the commutator segment on one side of the coil support piece 6. The coil is wound in the direction of the arrow in Figure A, and the end of the coil is connected and fixed to point b at the tip of the adjacent commutator segment. The other coils are wound in the same manner, and the beginning and end of winding of the coils are processed in the same way. This state is shown in FIG. Figure A shows a plan view, and figure at the front shows a side view. In addition, when the coil support piece 6 is formed of a capacitor for noise prevention in the above, a brush (

がなくなり回転子の製造効率が向上する利点がある。As mentioned above, the rotor of the present invention uses a conductive member such as a copper laminate when a flat plate commutator is constructed using a copper laminate having a copper plate on an insulator such as an epoxy resin. Since the commutator plate main body having the arm part and tip part on which the coil support piece is provided and the commutator segment is punched out, manufacturing is easy, and when constructing a rotor using this commutator plate, The winding start end of the coil provided between each commutator segment is connected to the bent part at the end of the coil support piece, and the winding end of the coil is connected to the tip end of the adjacent commutator segment. For,
At the beginning of the winding, there is no overlapping of the coils that are formed by being wrapped around the coil support piece, which reduces accidents such as coil shortcuts, which eliminates defective products and improves rotor manufacturing. This has the advantage of improving efficiency.
