Abstract

PURPOSE:To reduce the diameter of a motor and to obtain the prescribed torque of the motor by nonlinearly forming the side of an armature coil, and disposing a permanent magnet so that the pole surface formed by the side of the coil and the field magnetic flux are substantially entirely crossed perpendicularly. CONSTITUTION:A rotor hub 20 is secured to a shaft 10, and an armature coil 30 is secured to the hub 20. The sides 31, 32 of the coil 30 are nonlinearly formed. Permanent magnets 61, 62 are formed substantially in L shape, and the field magnetic fluxes which is formed by the magnets 61, 62 cross perpendicularly to the pole surface which is formed by the sides 31, 32 of the coil. When the coil 30 is energized, a rotary torque is produced at the sides 31, 32 of the coil by the field magnetic fluxes due to the magnets 61, 62.

いう効果を右づる。１[''There is a problem that when used in a LC mode, it creates resistance and reduces efficiency. In other words, in order to efficiently use the vortex layer, the following equation is generally expressed as the vortex layer. It must be J41. (Fan diameter)/<Motor diameter) < (1.4 However, if the diameter of t is too large as described above, the above equation cannot be satisfied. This was done in view of the conventional problems, and even if the axial length of 1:-3 and the diameter of 1111 were reduced, the required torque could not be produced even with respect to the propeller fin. The purpose of the present invention is to provide an efficiency of J and L. In order to achieve this purpose, the present invention forms the coil side of an armature coil in a non-straight line, Permanent magnets are arranged on the side of this coil so that the field magnetic flux generated by the magnetic pole surface is almost perpendicular to each other. There is a perspective view C showing one embodiment of the invention, and FIG. 2 is a vertical cross-sectional view of the embodiment at -.In FIG.
The shaft 10 has a circumference of 4t, (the hub 2 of the
30 is fixed at 0. coil 3
0 is the coil side 31 that cuts the magnetic flux and produces 1~
．． 32, 1...Cut the bundle and cut the coil end 33 that does not produce a loop. The coil sides 31 and 32 form part of the 1-character shape. In Figure 2, Comi-11-940 is 7/Mabu-1
It is made by connecting the ends of Noah coil 30,
A current is supplied through the brush 50 from the power supply shown in the figure. The brush holder 51 and permanent magnet ri61.62 are attached to the yoke 70. A fixed 1° permanent magnet (31, 62 is formed in an almost 1-shape, and the field magnetic flux generated by the magnet 61 at - is the same as that of the 16th point 111 created by the - coil side 31. J is perpendicular to J.Similarly, the magnet 62 is
The field magnetic flux generated by J3 is located on the coil side 32, and a part of the magnetic pole surface created by When the coil 30 is energized, a rotational torque J is generated on the coil side 31 due to the field magnetic flux generated by the magnet 61, and j is generated due to the field magnetic flux generated by the magnet 62.
Rotating magnetic flux is also generated on side 32! J: Zuru. therefore,
Since the Amaji core coil 30 is shaped like a letter, its diametrical shape is small and its axial length is long. Furthermore, since the diameter of the motor becomes smaller, the above equation can be transformed into a vortex layer, which improves the efficiency when rotating the propeller. However, if you use an anisotropic grinding stone, you can use just one magnet. Also, instead of having the magnets 61 and 62 in a straight line shape, it is also possible to make the magnets 61 and 62 into a curved shape and form the Amaji core coil 30 in accordance with this curve. Furthermore, magnets 61 and 62 may be placed on the outside of the Amaji Acoil 30. In this way, the present invention forms the -1 side of the 1-horn coil into a non-tI line, and the field magnetic flux is separated from the 1t pole face which is J, τi'1 on this coil side. By arranging the permanent magnets so that they are orthogonal to each other, it is possible to generate the required torque by reducing some of the axial lengths and diameters. On the other hand, [”b is the effect of good efficiency.1
