Description
Technical field
The present invention relates to a kind of permanent magnetism intermediate frequency brushless three-phase synchronous generator, especially a kind of permanent magnetism intermediate frequency brushless three-phase synchronous generator with double electric inducing voltage regulation function.
Background technology
At present, the intermediate frequency brushless three-phase synchronous generator is generally formed by main generator and AC exciter are coaxial, and this makes the electric machine structure axial length long.In order to shorten axial length, can save AC exciter part and make permanent magnetism intermediate frequency brushless three-phase synchronous generator, but this magneto pressure regulation difficulty, if not compound electric excitation pressure regulation, its voltage regulation is difficult to accomplish the level less than 3%.Existing compound rectifier excitation scheme is that permanent magnetism master motor is axially adding an electric exciter in addition, and axial length has so still extended.
Summary of the invention
Purpose of the present invention just provides a kind of permanent magnetism intermediate frequency brushless three-phase synchronous generator with double electric inducing voltage regulation function, and it both can keep the magneto axial length shorter, again can accurate voltage regulating.
The present invention is achieved like this, it comprises rotor core and stator core, it is characterized in that being provided with in the rotor permanent magnet, increase by two kinds of electric excitations in the groove of rotor core, first kind is to be wound with the self power generation coil in rotor, be closed into the self-rectifying excitation through diode, the electric excitation of this kind is proportional with the motor load electric current, second kind is the electric excitation that is formed by the stator excitation winding, it is connected with voltage regulator, by voltage regulator control input dc power excitation, about stator core is divided into two sections, place the stator excitation winding in the middle of it, about arrange with a kind of three-phase main winding and the auxiliary winding of three-phase in two sections stator core slots, these two kinds of windings are concatenated into the star winding of the band neutral line, also are furnished with the auxiliary winding of a cover separate single-phase in stator, and this winding provides direct current excitation by linking to each other with voltage regulator to stator DC excitation winding.
Good effect of the present invention is to have increased by two kinds of electric excitation technology structures in the magneto, can zero load generate electricity voluntarily and steady load voltage, makes permanent magnetism mid-frequency motor regulation be less than 3%, keeps the motor axial length shorter.

Embodiment
As shown in Figure 1, the present invention includes stator core (1) and rotor core (2), rotor core from left to right is divided into four sections, place rotor punching A (3), rotor punching B (4), rotor punching C (5), rotor punching A (3) successively, the rotor core both ends of the surface copper coin of rotor punching A (3) punch die punching out 1mm, firm with damping copper bar 6 welding of passing the rotor punching damping hole, 16 coils of layout pitch 1-2 in the groove of whole rotor, each coil links to each other with diode.About stator core is divided into two sections, connect by the stator yoke circle, the middle stator excitation winding 7 of placing is placed three symmetrical stator winding 8 in the stator core, and every phase winding is in series by main winding and auxiliary winding two parts.Like this, this have the permanent magnetism intermediate frequency brushless three-phase synchronous generator of double-current excitation function similar in appearance to the single pivot structural electromotor, simple in structure, the motor axial length is short more a lot of than the brushless generator of band AC exciter, and voltage-regulation is better than single permanent magnet generator greatly.
As shown in Figure 2, u1, v1, w1, n are three-phase four-wire system output armature winding mark in the stator, and u1, v1, w1 are in series respectively by three symmetrical main winding A1X1, B1Y1, C1Z1 and auxiliary winding a1x1, b1y1, c1z1.D1D2 is single-phase auxiliary winding, and Z is a single-phase bridge rectifier, and E1E2 is the stator excitation winding, and AVR is a voltage regulator, and regulating AVR is adjustable voltage.
In the rotor, YN1, YS1 ... YN8, YS8 are the permanent magnet of 16 utmost points, ZN1, ZS1 ... ZN8, ZS8 are that 16 coils become 16 electric excitation poles, EN1, ES1 with the diode self-rectifying ... EN8, ES8 are 16 magnetic poles that electric excitation forms that formed by direct current among the E1E2 in the stator.
When motor speed reaches rated value, u1, v1, w1, n produce Permanent Magnet and Electric and are pressed onto near rated value, D1D2 also produces voltage, regulate AVR and can make u1, v1, w1, the n rated value of adjusting, after inserting load, ZN1, ZS1 in the rotor ... ZN8, ZS8,16 coil-induced generatings become the electricity self-excitation to form 16 electromagnetic poles through diode rectification, automatically output voltage are regulated.In addition, regulate AVR, E1E2 forms electric excitation and makes EN1, ES1 ... EN8, ES816 electromagnetic pole excitation changes, and automatically output voltage carried out fine adjustment simultaneously.
When only permanent magnet excitation being arranged, voltage regulation only is 7-10%;
When only adding rotor self power generation excitation, voltage regulation can reach 5%;
When with after regulating AVR again, voltage regulation can be less than in 3%.
