Embodiment 1

[0095] Fig. 3 is a front view of the planetary gear motor of the present invention. The permanent magnets of the two-pole inner magnet rotor 1 of the present invention are integrally provided on the sun gear 6 , and the four planetary gears 7 are held so as to mesh with the sun gear 6 . The number of planetary gears is just an example. The planetary gear 7 is rotatably held by the carrier 10 , and is held rotatably by the meshing of the internal gear 8 and the planetary gear 7 . As an example, 12 toroidal coils 3 are neatly wound around the seamless toroidal core 2 on the outer periphery of the internal gear 11, and 12 input terminals 4 are provided. The method of generating the rotational force of the sun gear 6 is the same as that of the two-pole DC motor of the present invention.

[0096] Fig. 4 is a side sectional view of the planetary gear motor of the present invention. As can be seen from this cross-sectional view, the sun gear 6, the planetary gear 7, the internal g...

Embodiment 2

[0098] What Fig. 6 shows is that the ratio of the rotation diameter of the magnetic pole front end of the two-pole internal magnet rotor 1 of the present invention to the inner diameter of the annular iron core 2 conforms to the golden section ratio, that is, 61.80339%. The ratio of the magnetic attraction force between the poles inside the rotor 1 to the influence of the rotational torque is measured and derived from the results. What Fig. 7 shows is that the two-pole inner magnet rotor 1' of the plate magnet magnetic field is arranged according to the rotational diameter of the above-mentioned golden section ratio.

[0099] Compared with the two-pole internal magnet rotor 1 and the two-pole internal magnet rotor 1' shown in Fig. 5 and Fig. 8, the two-pole internal magnet rotor 1 and the two-pole internal magnet rotor 1' have large torque and slow rotation speed, so they are suitable for low-speed and high-speed rotation. moment.

[0100] As an example, the two-pole DC motor...

Embodiment 3

[0105] Fig. 11 and Fig. 12 are the figure that the two-pole inner magnet rotor 1 of the bar magnet magnetic field and the two-pole inner magnet rotor 1' of the plate magnet magnetic field are arranged at the armature center 5 deviated from the gapless annular iron core 2.

[0106] In the above-mentioned figures, the gap between the annular iron core 2 and the two-pole internal magnet rotor 1 or the two-pole internal magnet rotor 1' deviates as the feature of the present invention, and mechanical devices such as gears formed of non-magnetic materials can also be provided at the armature center 5.

[0107] As an example, the two-pole DC motor of the present invention is formed in the following manner, that is, the two-pole internal magnet rotor 1 having a bar magnet-type magnetic field as shown in FIG. Twelve toroidal coils 3 in which enamel copper wires with a diameter of 0.5 mm are wound 250 times are evenly arranged on the entire circumference of a toroidal iron core with an i...

Abstract

The invention provides an armature stator and a magnet rotor for a dipolar direct current electric motor. The armature stator consists of a seamless ring-shaped core and an even number of coils coiled along the full perimeter of the ring-shaped core in the same direction at an equispaced rotation angle. Both ends of the even number of coils are connected in series, and the connecting parts become terminals for power input. The magnet rotor is provided with a bar-shaped magnet magnetic field or a platelike magnet magnetic field which is perpendicular to the rotation axis of the rotor. The leading pole tip of the rotor is separate from the inner rim of the ring-shaped core. The invention further provides a generator comprising a direct current electric motor and a planetary gear mechanism which are combined, wherein, the rotation axis of prior electric motor is connected with the gear mechanism. The sun gear and the planetary gear of the planetary gear mechanism of the invention can be formed into one piece as magnet rotors of the electric motor in the structure of the electric motor. The invention can eliminate surge voltage and so on, and reduce noise.

Description

technical field [0001] The present invention relates to the combination of a DC motor and a gear transmission mechanism, and more specifically, provides a two-pole DC motor with new shape, performance and function that is most suitable for combination with a gear mechanism, and uses a planetary gear mechanism to reduce the number of motors driven by the armature. The reaction forms the reverse torque of the generator. Background technique [0002] In the prior art, the technology called a gear motor is shown in JP-A-2001-54255, in which a rotating shaft of a motor is connected to a gear mechanism and a frame is fixed to each other with screws. [0003] Also, as shown in Japanese Patent Laid-Open No. 2003-314634, the motor part and the gear mechanism part are arranged separately in the same housing, and are connected to each other through the motor rotation shaft. [0004] In addition, in a conventional DC motor, the rotor and the stator are arranged as close as possible, th...
