Abstract

PURPOSE:To improve the efficiency by forming a magnetic path by a coil with the parallel magnetic paths consisting of a magnetic path including a permanent magnet and that not including permanent magnet. CONSTITUTION:The teeth 15, 15' of yoke 1 are divided at the end portions as the yoke tooth end portions 16, 17 and 16', 17'. Moreover, the rotor 18 is composed of a rotor core 19, rotor teeth 20, 20' and permanent magnets 21, 21', and the core 1 and teeth 20, 20' are made of material having a high permeability. The teeth 20, 20' are respectively corresponding to the tooth ends 16, 16', and 17, 17' of teeth 15, 15'. The magnetic path by the magnets 21. 21' and the magnetic path by the coil 2 are separated and the magnetic path by the coil 2 is composed of the magnetic path including the magnets 21, 21' and the magnetic path not including these magnets provided in parallel. Thereby, an electromotive force by the coil 2 supplies a magnetic energy to a gap for generating a rotating torque mainly through the magnetic path not including the magnets 21, 21' and a permanent magnet having a small permeability can be eliminated from a magnetic circuit viewed from the coil 2.

Description

[Detailed description of the invention] The ambiguity is related to rotorinoid4).

f 疋3sU) The rotorinoid with Lφ has a structure in which the inner diameter of the yoke = the inner diameter of the rotor and the outer diameter of the rotor are cut an even number of 1,1.10 times, or it looks like Step 7-i'- υ〈 A permanent ji & stone with an even number of magnetic poles on two rotors every 4 months,
The same number of m full yaws and V are 41'♂
), the rotor is supported by a tJ4h receiver, and the yoke and rotor 1111 are energized by appropriately wound drive coils (hereinafter simply referred to as coils).
A common method is to supply magnetic energy to the gap created by the rotor to provide rotational torque to the rotor. Since the rotational torque given to the rotor at nM l- is proportional to the square of the air gap VC'++
- To increase, the magnetic flux 1'ff of the air gap must be increased. In the former type, the magnetic flux density IWb is generated only by the magnetomotive force generated by passing through the coil, so when the magnetomotive force is small, that is, when the input low force is small, sufficient recirculation l·lux is generated. I can't do it.

In the latter form, the ratio of the magnetic flux density B generated by the magnetomotive force V of the permanent magnet and the magnetic flux density S generated by the magnetomotive force of the coil to the square of U, that is, (B-1-1))
'4-ru. That is, rotational torque 'lj: is obtained as shown in equation (1).

T≧(B+b) = B +2Bb -1-b2 ・・
...(1) (1) The first term on the right side is the rotational torque generated by the permanent magnet and does not increase with K. The second and third terms are generated by the magnetomotive force of the coil, and can be determined by the amount proportional to l·l/C. According to equation (1), 7'1. Is the commercial torque T? In order to increase the magnetic flux densities B and bf, it is necessary to increase VC, but in the latter form as mentioned above, CI: Since the magnetic circuit as seen from the coil contains a permanent magnet with low magnetic permeability, the coil Magnetic flux due to 4Ih force causes large obstacles and 7! However, it is difficult to increase the efficiency of rotary lenoid.

This model was made in order to alleviate the above-mentioned drawbacks of the conventional model. The tooth end portion and the rotor tooth portion made with high permeability are separated into a magnetic path by a permanent magnet and a magnetic path by a coil, and the magnetic path created by the coil is completely included. Magnetic path and all permanent magnets
By forming a row-path in 31 with a path 1a without i, the magnetomotive force caused by the coil (〆C) creates an air gap in which the magnetic path that does not contain permanent 1st crystal mainly generates a torque of The drawings will be explained in detail below. Figures 1.7.S and 4 are schematic structural diagrams of conventional rotary linoids; A pot of a type that does not use a permanent magnet, and a side sectional view,
Figures 3 and 4 are horizontal and (lull +@ side views) of a type that uses permanent magnets for the rotor. is the rotor, O is the rotating torque extraction shaft, and O is the bearing. The yoke is made of a magnetic material with a high permeability rate of 4.7 mm, and the rotor teeth 7 are cut at 1%. The rotor 3 is also The rotor is made of high magnetic permeability material and has the same number of rotor teeth l as the yoke teeth 7.The rotor tag is magnetized with a permanent magnet in the diametrical direction VC71+j, and the yoke teeth Ht (17 and the same number of magnetic poles N, I have St.

>g+, 2:a, when the coil 2 is energized, a magnetic flux flows in the magnetic path seen from the coil as shown by the arrow, and the air formed by the yoke tooth section 7 and the rotor tooth section ♂ is Magnetic flux also passes through it. If the four-part flux density τb of the void 10 is b2
A rotational force proportional to acts on the rotor 3 in the direction of the arrow //,

In Fig. 4, magnetic flux first flows in the direction of the arrow along the magnetic path /2 due to the permanent magnet rotor tag, and magnetic flux also flows in the gap /3 created by the yoke teeth 7 and 7', the rotor tag, and V. Pass. The t1u flux density HtH due to the permanent magnet rotor tag with the air gap /3 is determined by B and ffl.The rotor tag is rotated in proportion to B' (r) in the direction of the arrow /g. Then, when coupled to the coil 2 in the direction shown in 3rd and 41゛4, the opposite direction of the arrow passes along the magnetic path /2 seen from the coil λ, and the rotor teeth 2 pass through the north pole. , the rotor tooth portion 7' becomes 84+ da.Magnetic flux also passes through the air gap /3 and its magnetic flux density is (B-b)2, and thereafter: · ma (B+b)2 The rotational torque that is compared to 2 acts in the opposite direction to the arrow /g.

However, the magnetic path seen from coil 2 /, 2 is the permanent magnet rotor (

, □11chi (almost the same as air) and ′(Uri, even alnico-based sulfurite can be reduced by about 10t. Therefore, if the magnetic resistance of the magnetic path is about 1, and the magnetomotive force is 11J1, then it is a magnet that does not contain a permanent magnet. The magnetic flux density 11b of 1.l/3 is very small compared to the road, and it is not possible to expect a highly efficient rotary linenoid metal.

So, axis! The rotational torque in the direction indicated by the arrow gradually decreases and reaches 0 at θ=-90°. The same goes for the frequency of θ>+00, and in the direction in which θ increases, -4 rotations'l·rook, which is indicated by arrow J, gradually decreases and reaches O at θ=+90°.

Considering the range of θ from -θ0 to +θ0, θ=
At -θ0, (0o 10) is 0, so the S and 5th terms become larger during the day, and the rotational torque T in the direction of the arrow
c(r is obtained. As θ gradually increases, the rotational torque Tc gradually decreases, but at θ-+00, it becomes 0 again in (θ0-θ), so the rotational torque Tc increases. However, it is smaller than the value of θ-#0. θ In the range where T decreases from -00, the rotational torque T

Furthermore, since it is possible to eliminate 0=Omin f at which the rotational torque TC is minimum, it is also possible to have a characteristic in which the rotational torque Tc is gradually reduced.

Next, if the direction in which the coil 2 is energized is reversed to -1-7'L, a rotational torque is generated in the direction shown by arrow 2, as is clear from the above explanation.
