Abstract
The present invention relates to a lap winding type single phase brushless generator, which comprises two kinds of windings arranged in a generator stator and the two kinds of windings are in a lap winding type. The present invention is characterized in that a stator main winding and an auxiliary winding of an excitation source are in the same slot; the main winding is in a lap winding type winding with size elements in equal turn, and the auxiliary winding is in a lap winding type winding with size elements in equal turn or unequal turn. The main winding and the auxiliary winding are in the same slot arrangement, so 1/3 of the number of the stator slot is not used, which is convenient for ventilation and heat radiation; the main winding has the equal turn to achieve sine requirements; the present invention has the advantages of less than 2% of distortion rate, and man hour and insulating material saving.
Description
Technical field
The present invention relates to a kind of lap winding type single phase brushless generator.
Background technology
Main winding is made the sinusoidal concentric type winding that does not wait circle in traditional single phase synchronous generator stator, and this winding number of turns is many, and every circle number of turn is unequal.Complex process is many during worker.Occupy many mistake 2/3 grooves of stator slot, make excitation source usefulness, then make nearly all to be furnished with winding in all stator slots, thereby blocked the stator slot ventilation, temperature rise when making inorganic motor if also need add auxiliary winding in this motor.
Summary of the invention
The object of the present invention is to provide a kind of lap winding type single phase brushless generator, it can vacate 1/3 stator slot as ventilation and heat usefulness, saves man-hour and insulating material.
The present invention is achieved like this, two kinds of windings are arranged in the generator unit stator, two kinds of windings all are repeatedly the formula windings, it is characterized in that: the auxiliary same groove of winding of stator main winding and excitation source in the generator, main winding is circles such as the big small components formula winding that changes, and auxiliary winding is circles such as big small components or does not wait the circle formula winding that changes.
Main winding of the present invention and auxiliary winding are arranged with groove, make number of stator slots vacate 1/3 groove number, make in ventilation and heat, and circles such as main winding reach the sinusoid requirement, and aberration rate is saved man-hour and insulating material less than 2%.
Description of drawings

Fig. 2 is an auxiliary winding layout plan of the present invention
Embodiment
Number of stator slots Z=24 of the present invention, number of poles 2 utmost points, single-phase, the stator main winding arranges that as shown in Figure 1, the winding number of turns is 8 circles, pitch is 2 kinds, a kind of Y
1=1-10, another kind of Y
2=1-5, the auxiliary winding of stator arranges that as shown in Figure 2 the winding number of turns also is 8 circles, pitch is 3 kinds, y
1=1-11, y
2=1-6, y
3=1-7, the winding turns ratio is made did not have first-harmonic content at 1: 1.5: 1.5 o'clock, made 1: 1.15: 1.15 o'clock first-harmonic content and was about 1/4.Harmonic content is about 3/4, also can make 1: 1: 1.This moment is also for mixing ripple, so auxiliary winding is as the self-excitation excitation source of brushless generator.Be to debug optimum, so that the every performance requirement that satisfies generator excitation, compound excitation, encourages and start asynchronous machine by force.Because auxiliary winding and the same groove of main winding, in 2 utmost point motors of number of stator slots 24, groove 5,6,7,9 and groove 16,18,19,20 8 grooves are empty, especially are fit to make no support motor.
Claims (1)
1, a kind of lap winding type single phase brushless generator, two kinds of windings are arranged in the generator unit stator, two kinds of windings all are repeatedly the formula windings, it is characterized in that: stator slot is vacated 1/3rd groove number and is used as ventilation and heat, save man-hour and insulating material, the auxiliary same groove of winding of stator main winding and excitation source in the generator, and the pitch of main winding is set at 2 kinds of sizes, 2 kinds of pitch elements are the repeatedly formula windings that wait circle, the pitch of auxiliary winding is set at 3 kinds of sizes, and 3 kinds of pitch elements also are to wait repeatedly formula winding circle or that do not wait circle.
