Abstract
An overlap winding type single-phase brush-free motor, there are two kinds of windings in the generator stator, which are both overlap windings. The feature lies in that the main winding of the stator and excitation source auxiliary winding are in the same slot. The main winding is the equal-turn overlap type winding for large and small elements, the auxiliary winding is the equal-turns or unequal-turns overlap type winding for large and small elements. The main winding and auxiliary windings of this utility model are arranged in the same slot, which leaves 1/3 of stator slots unoccupied for good ventilation. The main winding adopts equal-turns which satisfies sinusoid requirements with a distortion rate lower than 2%, saves man-hours and insulation materials.
Description
Technical field
The utility model 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 purpose of this utility model is to provide a kind of lap winding type single phase brushless generator, and it can vacate 1/3 stator slot as ventilation and heat usefulness, saves man-hour and insulating material.
The utility model 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.
The utility model main winding 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. 1 is a main winding layout plan of the present utility model.
Fig. 2 is an auxiliary winding layout plan of the present utility model
Embodiment the utility model number of stator slots Z=24, 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.
