きに頼らざるを得ないという問題があった。Most of the synchronous machines manufactured today are of the rotating field type. Such a rotating field type synchronous machine consists of a stator and a rotor on which a rotor winding fgA is arranged. The rotor of the synchronous machine of the present invention has a structure in which yokes and permanent magnets are alternately arranged (supported) radially. Conventionally, in order to alleviate torque irregularities (slots and ripples) that occur, the stator has been provided with an extra slot for accommodating the armature winding. for that,
The armature windings also had to be wound to accommodate the diagonal slots, creating manufacturing problems. In particular, there was a problem in that it was not possible to use automated methods for this type of winding, and the winding had to be done by hand.

ロータ軸線に対して傾斜していることｆ：特徴とする。In the rotor structure of the synchronous machine according to the present invention, yoke irons and permanent magnets are arranged alternately, and the outer circumferential surface of the yoke protrudes 17 from the outer circumferential surface of the permanent magnets to form a magnetic pole surface. f: is characterized by being inclined with respect to the rotor axis.
以下本発明の実施例について図面を参照して貌。Embodiments of the present invention will be described below with reference to the drawings.

心力に抗してこれを押える役目をする。The rotor is formed by alternately radially arranging permanent magnets 1 and yokes 2. Permanently planted, the stone IFil's has a rectangular semi-section and is laid parallel to the rotor shaft. Joint 1: (2 has a fan-shaped cross section L7, C) The apex of the shape is the rotor center F! !
Therefore, the permanent magnet l and the yoke 2 can form a hollow cylinder with almost no gap. The outer circumferential surface of the sector-shaped yoke 2 protrudes outward from the outer circumferential surface of the rectangular permanent magnet 1,
Form the field magnetic pole surface. A portion of this protrusion forms a fin protrusion 3 in the rotor axis direction, and serves to resist the outward centrifugal force of the permanent magnet 1 and hold it down.

能である。In the embodiment shown in the figure, the yoke 2Q is obtained by punching thin plates of ferromagnetic material into a fan shape and arranging them in the rotor axis direction, that is, stacking them. However, the yoke 2 can also be obtained from solid ferromagnetic material instead of as a laminate.

らされる。The name of the yoke 2 plate material is such that the triangular cross-section portion 4 that makes momentary contact with the permanent magnet 1 and the fan-shaped surface portion extending in the radial direction have the same shape, and the aforementioned protrusion 3 is inclined with respect to the rotor axis. An example of this slope is shown in Figures 1 to 3.
As shown in the figure. The outer circumferential surface of the yoke 2, including this inclined protrusion 3, constitutes a magnetic pole surface, and therefore, the electric machine prewinding np accommodation slot of the stator, which faces concentrically with this magnetic pole surface, is an oblique slot. The same effect is brought about.

を有する。As explained above, the present invention aims to overcome the difficulties in manufacturing when the yoke is disposed obliquely (xl) when the stator is formed into an oblique slot. The degree of this inclination (size) is determined by factors such as the number of frames for each specific structure, and is easily determined by those skilled in the art.1. as a permanent projection (
The structure that holds down the weight has a moving bed that allows the rotor of a synchronous machine to be obtained with a simple structure in which all parts are integrated.
