Abstract

PURPOSE: To obtain the torque of a permanent magnet rotating machine without generating an antitorque due to a magnetic repulsive force and braking due to a magnetic attractive force, by so providing its rotor permanent magnet and its stator permanent magnet as to cross their magnetic flux planes perpendicularly with each other. CONSTITUTION: On an output shaft 1, a plurality of rectangular-parallelopiped rotor permanent magnets 10 are provided, and their magnetic fluxes are to be in the circumferential direction. On a nonmagnetic material flange 4 supported by a bracket 3, sector-column stator permanent magnets 5 are provided. The magnetic flux Φ generated from the N pole of the stator permanent magnet 5 forms a magnetic path passing through the bracket 3 and its S pole. The bracket 3 is supported by a frame 6, and is connected with a bracket 7. On a nonmagnetic material flange 8 supported by the bracket 7, sector-column stator permanent magnets 9 are provided. The magnetic flux Φ generated from the N pole of the stator permanent magnet 9 forms a magnetic path passing through the bracket 7 and its S pole. The magnetic flux Φ generated from the N pole of the rotor permanent magnet 10 forms a magnetic path passing through the frame 6 and its S pole.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a permanent magnet rotating machine in which a rotating force is obtained by magnetic interaction between a rotor and a stator permanent magnet.

[0002]

2. Description of the Related Art A means for driving permanent rotation by magnetic interaction between permanent magnets is a long-standing dream of many people since the discovery of permanent magnets, but some embodiments have been proposed in the past. None have been put to practical use. That is, in many proposed examples, the magnetic flux directions of the rotor permanent magnet and the stator permanent magnet are set to be the same and the attraction force or repulsive force between the permanent magnets is used, but the rotor permanent magnet and the stator permanent magnet are used. Have a common problem that a permanent magnet rotating machine cannot be established because a repulsive force is generated when the two poles face each other and the rotor has a counter torque, or an attractive force is generated when the two poles face each other and the rotor is braked. I am doing it.

[0004]

In order to effectively achieve the above object, according to the present invention, a rotor permanent magnet and a stator permanent magnet are made to have a magnetic flux orthogonal to each other, and their magnetic pole faces are not in contact with each other. A permanent magnet characterized in that it is provided by being displaced in an axial direction or a direction orthogonal to the axis, and a magnetic force is exerted by an attractive force or a repulsive force by a magnetic interaction between magnetic flux orthogonal magnetic pole faces of a rotor permanent magnet and a stator permanent magnet. It consists of a rotating machine.

[0005]

Next, the operation of the present invention will be described. Since the rotor permanent magnet and the stator permanent magnet are provided with the magnetic pole surfaces having the magnetic flux orthogonal to each other, the rotor permanent magnet approaches the stator permanent magnet when the rotor permanent magnet approaches the stator permanent magnet. Attracting force, and on the other hand, when the rotor permanent magnet tends to separate from the stator permanent magnet, repulsive force can be generated respectively, so that permanent rotation drive can be performed.
