That is, in this motor, a blowout vent 2 and a suction vent 3 are formed in a case 1, and capacitor support pieces 5 disposed in each slot of a rotor 4 extend in the axial direction. It is characterized in that the protruding portion is used as a cooling fan 6 and protrudes in the axial direction of the rotor 4. When the rotor 4 rotates, the cooling fan 6 generates wind in the axial direction, which cools the coil 7 and iron core 8 of the rotor 4, which are heat-generating components, thereby preventing thermal deterioration.

The ventilation hole 3 of the circumferential trunk portion 12 is formed by forming a pair of cut lines 13 parallel to the circumferential direction and cutting and bending the piece 14 between the cut lines 13 inward, as shown in FIG. Case 1
The bent piece 14 positions the end of the magnet 11 so as not to obstruct the passage of the magnetic flux φ in the circumferential direction. 15 is a bearing stand, 16 and 17 are bearings, 18 is a terminal, 19 is a brush holding spring, and 20 is a brush.

２８はスラストはとめである。 The rotor 4 has an iron core 8 and a commutator 21 attached to a motor shaft 9. A coil 7 is wound around the iron core 8, and a metal such as aluminum is connected to the end face of the iron core 8 via an insulating sheet 22 for electrical connection and heat radiation. A spark prevention capacitor 25 is provided in each slot 24 of the iron core 8.
The lead wires 26 are soldered to the support plate 23 and the commutator 21. Furthermore, a capacitor support piece 5 that supports the spark prevention capacitor 25 in the circumferential direction and a support piece 27 that supports the spark prevention capacitor 25 in the radial direction (with respect to centrifugal force) are formed on the support plate 23. 5 is curved in the plate width direction and arranged in the radial direction of the rotor 4, and the insulating sheets 2, 2' are attached to the contact side of the coil 7, and the length direction is arranged in the axial direction. A portion extends beyond the iron core 8 to the surplus space A side of the rotor 4 and serves as a cooling fan 6.
28 is a thrust eyelet.

性能化を実現できるという効果がある。 As described above, the motor of this invention includes a case that has a plurality of air holes for blowing out and suction and holding magnets inside, a rotor that is rotatably held within the case, and a rotor that is rotatably held within the case. A spark prevention capacitor disposed in each slot of the rotor core, and a capacitor support piece provided with a cooling fan disposed in the slot to support the spark prevention capacitor and protrude in the axial direction of the rotor. This has the effect of preventing thermal deterioration of the motor and realizing higher performance of the motor without increasing the size of the motor.
