Abstract

PROBLEM TO BE SOLVED: To apply a small amount of permanent magnet, to miniaturize an electric machine, and to obtain high output arranging a permanent magnet on the side surface of a rotor core projection part, suppressing a magnetic flux being leaked to the core recessed part between magnetic poles and the projecting side surface of the magnetic poles, and increasing the effective magnetic flux. SOLUTION: A stator 1 has an armature coil 2, a rotor 3 consists of a core 4 with recessed and projecting parts on an air gap side surface and consists of a magnetic material such as S45C or a laminated silicon steel plate, and an NdFeB permanent magnet 7 is arranged on the side surface of a projecting part 5 that becomes the magnetic pole of the stator core 3. The permanent magnet 7 being provided on the side surface of the core projecting part 5 is magnetized in a peripheral direction, and a rotor core near the permanent magnet 7 and a magnetic path where the magnetic flux of magnet flows through the stator core 1 are formed. The magnetic flux of the permanent magnet 7 suppresses the leakage of the magnetic flux of the armature coil of the stator core to the side surface of the projecting part 4 of the magnetic pole of the rotor 3. Specifically, by suppressing the leakage magnetic flux, effective magnetic flux is increased, thus obtaining high output.

したリラクタンス型回転電機に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reluctance type rotating electric machine combining permanent magnets capable of rotating at high speed with a small size and high output by a novel field structure.

である。2. Description of the Related Art A conventional reluctance type rotating electric machine does not require a coil for forming a field in the rotor, and the rotor 3 can be constituted only by an iron core 4 having irregularities as shown in FIG. Therefore, the reluctance type rotating electric machine is simple and inexpensive.

In the reluctance type rotating electric machine, the rotor 3 has irregularities, so that the magnetic resistance is small at the convex portions 5 and large at the concave portions 6. That is, the magnetic energy stored by flowing a current through the armature coil 2 is different between the gaps on the protrusions 5 and the recesses 6. This change in magnetic energy produces an output. Also,
The convex portion 5 and the concave portion 6 need only have a shape that allows not only geometrical formation but also magnetic asperity (magnetic resistance and magnetic flux density distribution differ depending on the position of the rotor).

The armature is the same as the reluctance type rotating electric machine, but the rotor has an iron core and permanent magnets arranged over almost the entire circumference of the rotor.

出力が得られる。Next, technical problems in the above-mentioned conventional machine will be described. The reluctance type rotary electric machine has different magnetic resistance depending on the rotational position due to the unevenness of the rotor core surface. With this change, the magnetic energy also changes, and an output is obtained.

However, since permanent magnets are arranged on the surface of the rotor core, a considerable amount of permanent magnets is required. Therefore, an object of the present invention is to provide a reluctance type rotating electric machine that can obtain a small size and a high output by using a small amount of permanent magnets.
