Abstract
The invention discloses a kind of small three-phases that can start heavy duty to brush hair motor stator winding, fundamental wave winding and auxiliary winding including stator winding, there is brush synchronous generator suitable for the three-phase of below power 12kW, it is characterized in that, in the winding, its main fundamental wave winding is low harmonic winding, and auxiliary winding is a kind of winding of special shape design.In this winding, main winding is designed using double-deck low harmonic winding, and Double Layer Winding selects short pitch, can reduce electromagnetic wire dosage, improves electric property, irregularity of wave form<1%, close to perfect sine wave；Well-designed auxiliary winding uses special form, and there is high energy to export, and the motor for possessing starting power close with rated output of generating set is fully loaded with load.
Description
Technical field
The present invention relates to technical field of generators, the small three-phase for being specifically particularly to that heavy duty can be started has
Brush hair motor stator winding.
Background technology
It is well known that according to JB/T3320.1-2000《Small-sized brushless three-phase synchronous generator》Standard gauge determines rated power
(P) 12kW and following three-phase synchronous generator should ensure that the general purpose rated power of unloaded across-the-line starting for 0.7P, 4 poles
Threephase asynchronous.
In practical situations, threephase asynchronous is all with load, especially low power water pump load and wind
Machine loads, it is necessary to which Seeking Truth starts at full capacity.It is such special that modern common three-phase has the synchronous small power generation unit of brush that cannot meet
The demand of user adds purchase cost, it is necessary to buy the generating set more several times greater than class bearing power to realize, must be requested that
The high request for meeting user is designed with new winding construction.
The content of the invention
The purpose of the present invention synchronously brushes hair motor rated power in below 12kW, stator aiming at a kind of small three-phase
36 slots, number of poles be 2 poles, design a kind of stator winding, make generator overcome the problems, such as it is above-mentioned be difficult to full load starting motor fault, make
Generating set can perfect full load starting motor similar in rated power therewith.
The technical issues of of the invention is to be achieved by the following technical programs：
A kind of small three-phase that can start heavy duty brushes hair motor stator winding, including main winding and auxiliary winding, main winding
It is designed using double-deck low harmonic winding so that unloaded and fully loaded line voltage irregularity of wave form is not more than 1%, and auxiliary winding is single double-deck
Design, containing three ripple harmonic energies and draws, and is supplied by automatic voltage regulator (AVR) or digital voltage adjuster (DVR)
To Exciting Windings for Transverse Differential Protection.
The advantages of this main winding and auxiliary winding, is：
(1) main winding does not wait circles Concentrical winding to be double-deck, using suitable turn ratio so that the zero load of generator and full
It carries line voltage irregularity of wave form and is not more than 1%.
(2) auxiliary winding is single double-deck pattern, containing triple-frequency harmonics energy, than using common three ripple harmonic windings and fundamental wave
The pattern of auxiliary winding series connection is simple, saves enameled wire dosage.
(3) heave-load device close with rated output of generating set, such as the load of the pumps of full and down can be started.
Description of the drawings
Fig. 1 is the stator main winding expanded view of the present invention.
Fig. 2 is the stator auxiliary winding expanded view of the present invention.
Specific embodiment
The present invention is further elaborated below by specific embodiment and with reference to attached drawing.
It is three-phase in figure, 2 poles, 36 slots brush hair motor bilayer low harmony wave main winding expanded view referring to Fig. 1, wherein each
The coil turn of pole phase group is by different turn ratio generator line voltage harmonic waves containing low, MgO-ZrO_2 brick 6, section
Away from respectively 1-18,2-17,3-16,4-15,5-14,6-13, turn ratio 28.56：24.64：19.99：14.74：9.02：
3.04.A phase is only drawn in figure.
It is three-phase in figure, 2 poles, 36 slots brush hair motor auxiliary winding expanded view referring to Fig. 2, wherein four sets of coils altogether, wherein
First group of pitch is 1-10,2-9,3-8,4-7, and second group of pitch is 7-16,8-15,9-14,10-13, and the 3rd group of pitch is 19-
28,20-27,21-26,22-25, the 3rd group of pitch is 25-34,26-33,27-32,28-31, and mode of connection is as shown in Figure 2.
The auxiliary winding number of turn is according to required voltage design.
In addition to content described herein, affiliated those skilled in the art can be to this with reference to described above and attached drawing
A variety of improvement are made in invention, should all be considered as belonging to protection scope of the present invention.
