Problems solved by technology

First, since there is a gap between the permanent magnet member and the flux control ring, a holding tube of non-magnetic material such as SUS304 installed to fix the permanent magnet to the rotor, there is a gap, which becomes a magnetic field for the magnetic circuit path. The resistance increases, and the magnetic flux density decreases significantly
Second, regardless of the magnetic flux of the permanent magnet, it is necessary to increase the number of coils required to obtain a high power generation voltage that can be generated by the magnetic force, but the space for storing the coils is small.
Fifth, in order to perform flux c

Abstract

A permanent-mannet generator, setting a pectination front end part on a stator and a pectination teeth part on a magnetic flux control loop locating opposite with the stator. To make the magnetic flux control loop rotate and swing, and to change area of the pectination teeth part opposite to the pectination front end part, and to restrain magnetic flux through the magnetic circuit as well as to generate electric power of constant voltage. Forming chamfering edges parts on two turning parts in cycle direction of the pectination teeth part and the pectination front end part, so as to form gap of magnetic flux interspace with accuracy.

Description

technical field [0001] The invention relates to a permanent magnet generator, which comprises a rotor with permanent magnets, a stator disposed opposite to the rotor, and a magnetic flux control ring that is rotatably arranged relative to the stator to control magnetic flux. Background technique [0002] In the prior art, since permanent magnets are used for the rotor, a large power generation can be obtained with a simple structure. In recent years, systems incorporating such generators have been used as generators for automobiles, wind power generators, etc. There are more and more phenomena. A permanent magnet generator, for example, can fully perform its function even if the voltage changes when sending the generated electric power to the motor, but it is necessary to adjust the voltage when matching this electric power with the battery voltage of all devices that drive the car. Variations coincide with constant voltage operation. In permanent magnet generators, in ord...
