Abstract

In a magneto generator, second phase lead wires (10a, 10b) and third phase lead wires (11a, 11b) among individual one pair of first, second and third lead wires (9a, 9b; 10a, 10b; 11a, 11b) are covered with first protective tubes (12a, 12b), respectively. The second phase lead wires (10a, 10b) and the third phase lead wires (11a, 11b) covered with the first protective tubes (12a, 12b) are bent toward the first phase lead wires (9a, 9b) in a circumferential direction and bundled together with the first phase lead wires (9a, 9b). The first phase lead wires (9a, 9b), the second phase lead wires (10a, 10b) and the third phase lead wires (11a, 11b) thus bundled are bent in a direction opposite to the circumferential direction and covered with second protective tubes (22a, 22b, 22c), respectively.

Claims

1. A magneto generator comprising:

a flywheel that rotates about an axis of rotation;

a plurality of permanent magnets that are arranged on an inner peripheral wall surface of said flywheel in a circumferential direction thereof and fixedly secured thereto;

a stator core that is arranged at a diametrally inner side of said flywheel with its outer peripheral surface being in opposition to said permanent magnets; and

a three-phase magneto coil that has an conductor wound around each of teeth that are formed on an outer peripheral portion of said stator core so as to radially protrude in diametrally outer directions at equal intervals;

wherein said second phase lead wires and said third phase lead wires among individual one pair of said first, second and third phase lead wires of said magneto coil which are led out in an axial direction at circumferential intervals are bent in a circumferential direction toward said first phase lead wires, and bundled together with said first phase lead wires; and

said first phase lead wires, said second phase lead wires and said third phase lead wires thus bundled are respectively bent in a direction opposite to said circumferential direction.

2. The magneto generator as set forth in claim 1, wherein said second phase lead wires and said third phase lead wires are covered with first protective tubes.

3. The magneto generator as set forth in claim 1, wherein said first phase lead wires, said second phase lead wires and said third phase lead wires thus bent in a direction opposite to said circumferential direction are covered with second protective tubes, respectively, and said second protective tubes are arranged in a row along a diametral direction.

4. The magneto generator as set forth in claim 2, wherein said first protective tubes are fixedly attached to an end face of a coil end of said magneto coil.

5. The magneto generator as set forth in claim 1, wherein said first phase lead wires, said second phase lead wires and said third phase lead wires are arranged between said individual teeth , respectively.

6. The magneto generator as set forth in claim 1, wherein said first phase lead wires are arranged at locations more apart from a lead composed of lead portions for leading out to electrical equipment than said second phase lead wires and said third phase lead wires.

7. The magneto generator as set forth in claim 2, wherein one first phase lead wire among one pair of said first phase lead wires is wound around said second phase lead wires and said third phase lead wires covered with said first protective tubes together with the other first phase lead wire to bundle them together.

8. A magneto generator comprising:

a flywheel that rotates about an axis of rotation;

a plurality of permanent magnets that are arranged on an inner peripheral wall surface of said flywheel in a circumferential direction thereof and fixedly secured thereto;

a stator core that is arranged at a diametrally inner side of said flywheel with its outer peripheral surface being in opposition to said permanent magnets; and

a magneto coil that has an conductor wound around each of teeth that are formed on an outer peripheral portion of said stator core so as to radially protrude in diametrally outer directions at equal intervals, said magneto coil also having a lead wire that is led outwardly from said stator core;

a lead that has one end portion thereof electrically connected to said lead wire and the other end thereof electrically connected to electrical equipment; and

a lead clamp that has a basal end fixedly attached to said stator core by a tightening element, and an opening portion that opens to said magneto coil;

wherein said lead clamp covers said lead and at the same time presses said lead toward said magneto coil through said opening portion.

9. The magneto generator as set forth in claim 8, wherein said lead clamp is arranged between adjoining ones of said teeth when viewed along the direction of said axis of rotation.

10. The magneto generator as set forth in claim 8, wherein said lead clamp has a bent portion whose diametral outermost portion is bent toward said magneto coil.

11. The magneto generator as set forth in claim 8, wherein said lead clamp is formed with a plurality of protrusions protruding to said magneto coil.

12. The magneto generator as set forth in claim 8, wherein an elastic member is arranged between said lead clamp and said lead.
