Abstract
The present invention is the permanent-magnet synchronous AC generator according to the electromagnetic induction principle design, adopt permanent magnet or magnetic material to make the rotor of generator, drag with power and can send single-phase or three-phase alternating current, simplify the manufacturing process of synchronous alternator to a great extent.
Description
Synchronous alternator always is by the stator partial stator, and the rotating part rotor is formed.Produce magnetic field by the small-sized DC generator or the field winding on other direct-current power supply rotor electromagnet that are contained on the same axle of synchronous generator, transfer to produce electric current in the stator inward turning.The synchronous alternator in modern age removes DC generator through improving, and one group of auxiliary winding of embedding will assist the alternating current of winding to become direct current through rectifying device, for the required DC power supply of rotor-exciting in stator slot.Common have a triple-frequency harmonics, phase compounding, and reactance shuntings etc. are alternating current generator synchronously.Useful in recent years miniature motor is loaded onto the capacitor group of suitable capacity, and with the asynchronous generator of capacitive excitation, the electricity that is sent is except that supplying illumination, and electric current can not be used as power.In addition, the generator of also useful permanent magnet making.As the generator of hand set magneto, the generator model of generator in the hand pressing flashlight and teaching usefulness etc. can only send single phase poaer supply, but its power are very little.As for three-phase permanent synchronous generator power kilowatt more than the person, the motor document does not still have record.
The present invention is according to electromagnetic induction principle, and comprehensive synchronous generator and hand magneto generator manufacture method design.Be characterized on the basis of synchronous generator, removing small-sized DC generator and excitation winding, and remove devices such as rotor winding, electromagnet, slip ring, carbon brush, make rotor with permanent magnet or magnetic material, the stator slot aperture is loaded onto the alternating current winding after crossing improvement.Drag rotor through power, can send three-phase alternating current, the rotor manufacturing, be some with permanent magnet (or magnetic village material), make the alternate non-salient pole in north and south (garden cylindricality) rotor, how many numbers of poles needs to decide on design, and the slotted eye of stator punching needs suitably to strengthen to deepen, make it to pack into according to the electromagnetic wire of design needs, have no carbon brush simultaneously, electric capacity reduces steel, the simplification of steel consumption production technology, improve work efficiency, easy maintenance etc.
Development prospect of the present invention, as improve generator speed and can directly obtain high-frequency current more than 50 cycles, if the rotor of the generator of several same models is contained on the same axle, can become a generating set, parallel running, need not joint operating device, being used for hydropower station, flood season can all generate electricity.Low water can be looked hydraulic condition, and the outlet line of breaking part motor can lighten the load, and unit is normally moved; As asynchronous motor is reequiped generator, only needing more, exchanging rotor can become synchronous alternator with the change stator winding.
The present invention please announces and examination as to substances in advance.
