A coil group 1 for each vehicle is formed. Incidentally, the conductive wire is drawn out from the winding frame for each required number of turns as shown by a in FIG. 8, continuously wound, and cut at this portion to form the connection lead 2. This coil group 1 is made into a flat plate by temporarily adhering and holding the conductors on the coil sides with insulating tape 3 so that the shapes of the conductors do not collapse, and then taking it out from the winding frame and pushing down one coil side in the direction of the winding axis. to form. Note that the connection lead 2 is made to have an appropriate length and the insulating coating at the tip is removed.

作される。 The coil group 1 formed in a flat plate shape in this way is
As shown in Fig. 9, the coil end 1 on the connection lead 2 side
d is glued and wound around the outer periphery of the rotor hub 6, the parts where the conductor wires on both sides of the coil group are layered are overlapped to form a cylindrical shape, and the joints at both ends of the coil group are temporarily fixed with insulating tape or the like. Thus, a cylindrical coil 10 is formed. Insulation 7 for rotor hub 6
A commutator 8 is provided through the commutator, and a riser 9 is provided in the radial direction from each commutator.
Since the connection leads 2 are connected to risers at different positions depending on the number of poles, they are bent so that they align with the risers at predetermined positions as shown in FIG. 10, and so that the connection leads are aligned with each other in an orderly manner. Since the coil group is cylindrical, this bending process involves manually bending each coil one by one to the riser position, and once the bending process is complete, the connection lead end is pressed against the end face of the riser and welded to make an electrical connection. Next, the outer periphery of the cylindrical coil 10 is covered with a jig outer mold 4a, and a thermosetting resin is impregnated and cured, and after curing, the jig outer mold and inner mold are removed. In this way, a cup-shaped rotor with one coil end supported by the rotor hub 6 is manufactured.

Since the coil is cylindrical, each connection lead 2 must be bent one by one at the coil end and aligned with the predetermined riser position, which requires a lot of work to bend each lead to the correct position. Since the connection lead 2 was only bent and not fixed, when welding it to the riser 9, it was necessary to adjust the tip of each connection lead to the riser position and press it down again, resulting in poor workability.
