Embodiment 1

[0096] image 3 It is the 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.

[0097] Figure 4 It 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,...

Embodiment 2

[0099] Image 6 It is shown that the ratio of the rotation diameter of the front end of the magnetic pole of the two-pole inner 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%, which is based on the inner diameter of the annular iron core 2 and the two poles. The ratio of the magnetic attraction force between the magnet rotor 1 and the influence of the rotational torque is measured and derived from the result. Figure 7 Shown is a two-pole inner magnet rotor 1' of a plate magnet magnetic field arranged according to the rotation diameter of the above-mentioned golden ratio.

[0100] Two-pole inner magnet rotor 1 and two-pole inner magnet rotor 1' with Figure 5 and Figure 8 Compared with the two-pole internal magnet rotor 1', the shown two-pole internal magnet rotor 1 has a larger torque and a slower rotation speed, so it is suitable for low speed and high torque.

Embodiment 3

[0106] Figure 11 and Figure 12 For the two-pole inner magnet rotor 1 of the strip magnet magnetic field and the two-pole inner magnet rotor 1' of the plate magnet magnetic field are arranged on the figure deviated from the armature center 5 of the seamless annular iron core 2.

[0107] 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.

[0108] As an example, a two-pole DC motor of the present invention is formed in the following manner, that is, having Figure 11 The rotating diameter of the two-pole internal magnet rotor 1 of the bar magnet type magnetic field shown is formed to be 33 mm, and 12 holes are evenly provided on the entire circumference of the annular iron core 2 with an inner diameter of 130 mm...

Abstract

The invention provides an armature stator and a magnet rotor of a dipolar direct current motor, wherein, the armature stator is composed of a seamless annular core and an even number of coils wound around the full contour of the annular core in equally spaced rotating angles; the even number of coils are connected in serial by the two ends; terminals applicable to electric power input are formed by each connection position thereof; the magnet rotor is provided with strip magnet field or slabby magnet field; the magnet files are vertical to a rotating shaft of the rotor; clearance is arranged in the front end of a magnetic pole and internal periphery of the annular core. The invention also provides a generator with a combination of a direct current motor and a planetary gear mechanism, wherein, the rotating shaft and the gear mechanism of a current motor are connected. A sun gear and a planet gear of the planetary gear mechanism of the invention can be formed in one whole body as the magnet rotor of the motor in the structure of the motor. According to the armature stator and the magnet rotor of a dipolar direct current motor, occurrence of surge voltage can be eliminated; noises can be lowered.

Description

[0001] This application is a divisional application with application number 200610086445.1 and titled DC motor and generator filed on June 21, 2006. technical field [0002] 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 [0003] 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. [0004] 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 ot...
