The problem was that it was not possible. This is due to the following reasons.

) (lb) and the permanent magnet rotor (2) cause rocking motion by alternately repeating attraction and repulsion, and the rocking motion gradually amplifies and finally shifts to rotational motion. The direction of rotation was determined entirely by chance, depending on which side the transition point from rocking motion to rotary motion was located. In addition, some magnetic pole parts (
There are examples of attempts to regulate the rotation direction by making the air gap between la) (lb) and the permanent magnet rotor (2) uneven, or by disturbing the magnetic force distribution of the permanent foundation stone rotor (2). , although it is effective in the direction of initial motion, it cannot be used to regulate the direction of rotational motion because it is the initial motion of rocking motion.
本発明は上記問題点を解消した小型同期電動機を提供す

独立させたものである。Means for Solving the Problems In order to solve the above problems, the small electric motor of the present invention includes a stator core provided with a driving coil, a rotor formed of permanent magnets, and a bearing that supports the rotor. The stator core is separated into a plurality of parts in the thrust direction and each part is made independent.

上記構成によれば、永久磁石回転子の起動に関しては、
駆動コイルに通電すれば従来と同じように永久磁石回転

置する永久磁石回転子の磁軸を磁束の位相ずれ角に相当

。Effect According to the above configuration, regarding starting of the permanent magnet rotor,
When the drive coil is energized, the permanent magnet rotor performs an oscillating motion and transitions to rotational motion, as in the conventional case, but since multiple magnetic paths are configured, the phase of the magnetic flux is shifted. By forming a rotating magnetic field and further shifting the magnetic axes of the permanent magnet rotors located in each magnetic path by an angle corresponding to the phase shift angle of the magnetic flux, the direction of rotation is regulated.
この結果、永久磁石回転子の回転方向は偶然に頼ること
なく一方向回転となる。As a result, the permanent magnet rotor rotates in one direction without depending on chance.
実施例
以下、本発明の一実施例を第１図〜第５図に基づいて説
明する。EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 5.
第１図において、（ｌｌａ）及び（ｌｌｂ）は電磁鋼板
等を積層して構成された固定子鉄心で、非磁性体で形成
されたスペーサー（ロ）により互いに分離され。In FIG. 1, (lla) and (llb) are stator cores constructed by laminating electromagnetic steel sheets, etc., and are separated from each other by spacers (b) made of a non-magnetic material.

する磁石の磁軸（ａ）及び（扮を角度αだけずらし、さ
らに。The magnetic path consists of two circuits. (18a) and (18b)
is a permanent magnet rotor having a rotating shaft 04, and stator cores (lla) and (llb) each have a drive coil (
15a) and (15b) are installed, and bearing bodies (17
a) and (17b) are fixed by screws (to) so as to face each other. The permanent magnet rotors (18a) and (18b) are arranged so that the magnetic axes (a) and () of the magnets located in the two magnetic paths are shifted by an angle α as shown in FIG.

８ｂ）の磁石は分離独立の必要はなく、一体で着磁のみ
変えても同様の効果を有する。As shown in FIG. 8, by inserting a capacitor (19) as a component that changes the phase in series with one of the drive coils (15a), as shown in FIG.
The phases of the currents flowing in 5a) and (15b) are shifted by α. By shifting the phase of the drive current, the magnetic flux generated in the two stator cores (lla) and (llb) also shifts in phase by α. In addition, the permanent magnet rotor (18a) (1
The magnets 8b) do not need to be separate and independent, and the same effect can be obtained even if they are integrated and only the magnetization is changed.
以下、上記構成における作用について説明する。The effects of the above configuration will be explained below.

石回転子（１８ａ）（１８ｂ）は−気に回転運動に移行
することは稀であり、当初は揺動運動を繰り返す。When the permanent magnet rotors (18a) (18b) are stopped, they are balanced at a position where the middle of the magnetic axes (a) and Cb) are parallel to the magnetic poles, so depending on the position of the phase angle of the applied voltage, it can move in either direction. But there is a possibility that it will start. However, the permanent magnet rotors (18a) and (18b) rarely shift to rotational motion, and initially repeat rocking motion.

ようとする。第４図の時刻ｔ１から半周期の間はこれら
の動作を繰り返し１次の半周期で右回転の同期運転へ移
行しようとする動作を、完全に同期するまで繰り返す。At this time, in the configuration of this embodiment, the driving force is always in the same direction in one direction and works to continue rotation, but when an attempt is made to rotate in the opposite direction, the driving force and the reversing force work alternately.
The overall propulsion force in the opposite direction is weakened. Figure 5 (a
) As shown in (b), in a stable state, the magnetic axes of the permanent magnet rotors (18a) (IJb) are deviated by an angle α, so
It is stable with a deviation of α/2 from the magnetic pole center. Further, the winding direction of the drive coils (15a) (15b) is
When the current in the figure is positive, the left side of the magnetic poles in Figures 6(a) to (d) becomes the north pole. It is configured. Further, the A phase in FIG. 4 is a current flowing through the drive coil (15a), and the B phase is a current flowing through the drive coil (15b). In addition, (c) shown in Fig. 2 is the magnetic axis (b) of the permanent magnet rotor (18b).
This is the virtual phase magnetic axis that is translated in parallel. Regarding the starting direction, from time t1 in FIG. 4, the half period π is a left rotation, and the remaining half period is a right rotation. When started with clockwise rotation, the driving direction is the same throughout the entire cycle, and clockwise rotation continues. Also, if the voltage is applied at the time position shown in Fig. 4, the left magnetic pole of both stator cores (lla) and (llb) becomes the north pole.
The B phase is larger and the magnetic flux passing through the stator core (llb) is larger, so the permanent magnet rotor (18a) (18b)
is a left rotation. However, if we consider the time after 1 time t2, △ looks like a mountain (Fig. 5 (C)), and the polarity of the magnetic poles is reversed, so the permanent magnet rotor (18a) (18
The force acting on b) becomes a force in the clockwise rotation direction and attempts to prevent counterclockwise rotation. These operations are repeated during the half cycle from time t1 in FIG. 4, and the operation of shifting to clockwise synchronous operation in the first half cycle is repeated until complete synchronization is achieved.
なお、駆動コイル（１５ａ）（１５ｂ）の巻き方向及び
永久磁石回転子（１８ａ）（ｌｌｌｂ）の磁極の配置に
より、回転方向は自由に設定できる。Note that the rotation direction can be freely set depending on the winding direction of the drive coils (15a) (15b) and the arrangement of the magnetic poles of the permanent magnet rotors (18a) (lllb).

ものの、短時間後には一方向回転へ移行するため、従来

。By repeating these rocking movements, the rotation finally shifts to one direction. In addition, the permanent magnet rotor (18a)
When the moment of inertia of (18b) is very small, there is almost no rocking motion, and it shifts to rotational motion and reverse rotation, but due to the same effect as the rocking motion described above, it ends up in one direction. Move to.゛As a result, the permanent magnet rotor (
18a) (18b), although the direction of rotation is not determined immediately after startup, the rotation direction shifts to one direction after a short time, so there is no problem that the direction of rotation is not determined as in the conventional case.
また本実施例においては、スラスト方向に磁極数を増す
ため１回転子の直径を大きくする必要がなく、回転子の
慣性モーメントを小さく抑えることもできる。Furthermore, in this embodiment, since the number of magnetic poles is increased in the thrust direction, it is not necessary to increase the diameter of one rotor, and the moment of inertia of the rotor can be kept small.

形状は共通であり、生産性の向上を図ることもできる。Effects of the Invention As described above, according to the present invention, since a plurality of separate and independent magnetic paths are configured in the thrust direction, the direction of rotation can be regulated by generating a magnetic field for one rotation, and at the same time, the permanent magnet type The number of magnetic poles can be increased without significantly increasing the moment of inertia, which has the most negative effect on starting small synchronous motors.Furthermore, the shape of the stator core remains the same even if the number of magnetic poles is increased or decreased, improving productivity. You can also try it out.
