As one of the two magnetization surfaces of the permanent magnet contacts with the stator pole core while the other one of the magnetization surfaces of the permanent magnet contacts with the air gap, the magnetic field generated by the permanent magnet forms a closed loop through the air gap, a rotor core, a stator yoke and the stator pole core, and a build-up excitation magnetic field needed by self-excitation voltage buildup is provided when internal residual magnetism magnetic fields of a main generator and an exciter core are insufficient.
Description
Technical field
The present invention relates to technical field of motors, relate in particular to a kind of compound rectifier excitation formula AC exciter.
Background technology
Due to the field power supply of self-excitation brushless excitation system without the outside supply, the exciting current of AC exciter needs to be produced by main generator and excitation system itself thereof; Therefore, excitation system could work after needing self to set up excitation voltage.
Usually, set up excitation voltage, need main generator and AC exciter inside unshakable in one's determination to have certain remanent magnetism magnetic field intensity.When main generator and AC exciter inner residual magnetization unshakable in one's determination does not reach when requiring, excitation system can not be set up excitation voltage, normally excitation.
Summary of the invention
The object of the invention is to overcome above defective, a kind of compound rectifier excitation formula AC exciter of energy self-excitation build up is provided.
for achieving the above object, the present invention takes following design: a kind of compound rectifier excitation formula AC exciter, it comprises magnetic pole of the stator and rotor, rotor is placed in magnetic pole of the stator, leave air gap between rotor and magnetic pole of the stator, magnetic pole of the stator comprises that magnetic pole of the stator is unshakable in one's determination, excitation winding, permanent magnet, excitation winding is wound on the magnetic pole of the stator iron core, in two faces that magnetize of described permanent magnet, one side contacts with magnetic pole of the stator is unshakable in one's determination, another side contacts with air gap, the surface that described permanent magnet contacts with air gap not with the interference of rotor outer circle face, the magnetic field that described permanent magnet produces is consistent with the magnetic direction that excitation winding produces.
For easy for installation, the internal circular surfaces of described magnetic pole of the stator iron core is provided with groove, and the overall dimension of groove size and permanent magnet is complementary, and described permanent magnet is placed in groove.
Described permanent magnet is cemented in groove by seccotine.
The height dimension of described groove is consistent with the height dimension of permanent magnet.
The height dimension of described groove is larger than the height dimension of permanent magnet.
The height dimension of described groove is less than the height dimension of permanent magnet.
Effect of the present invention is: contact because one side in two faces that magnetize of permanent magnet and magnetic pole of the stator are unshakable in one's determination, another side contacts with air gap, the magnetic field that permanent magnet produces forms the closed-loop path via air gap, rotor core, stator yoke, magnetic pole of the stator iron core, when main generator and exciter inner remanent magnetism unshakable in one's determination magnetic field is inadequate, provide self-excitation build up required excitation excitation field.Particularly permanent magnet is arranged in the groove on magnetic pole of the stator surface unshakable in one's determination, the occupying volume external space, not simple in structure.
