Description
Technical field
The present invention relates to a kind of tapping mode of speed regulation of alternating current motor.
Background technology
At present, when alternating current motor need be realized a plurality of rotating speed, great majority adopted tapping modes to realize speed governing.Generally, this tap mode of speed regulation is that each speed governing winding coil is distributed in its corresponding each coil fifty-fifty.Such as a single-phase adjustable-speed motor, its mode of speed regulation is to realize by auxiliary winding tap mode.Existing auxiliary winding is made up of 4 coils, and the total number of turns of its 1st speed governing winding is 120 circles, and this 120 circle is divided into 4 equal portions so, be distributed in 4 coils, and in each coil 30 circles.Other speed governing winding and the like, also be evenly distributed in these 4 coils.On technology, after it was achieved in that and at first is fully inserted into the 1st speed governing winding in the stator slot, distinguishing the winding of other speed governing successively again, (in order) embedded in each stator slot; As shown in Figure 1, three speed governing windings are arranged, before the coiling, earlier selected first groove (1) is the tap top of three winding coils, and the tenth groove (10) is the tap buttock line of three windings; The winding mode of first speed governing winding is: coiling between first groove (1) and the 7th groove (7), after the number of turn of intact designing institute regulation, this line is cross over second groove (2) continuously from the 7th groove, between second groove (2) and the 8th groove (8), after the equal number of turn that winds the line between intact first groove (1) and the 7th groove (7), from the 8th groove, be cross in the 15 groove again, between the 15 groove (15) and the 9th groove (9), after the equal number of turn that winds the line between intact first groove (1) and the 7th groove (7), from the 9th groove, be cross in the 16 groove again, between the 16 groove (16) and the tenth groove (10), after the equal number of turn that winds the line between intact first groove (1) and the 7th groove (7), the tail end of winding coil comes out from the tenth groove, is the tail end of first tap winding; The tap top of second speed governing winding coil is at first groove, method for winding is identical with the method for first speed governing winding, coiling between first groove (1) and the 7th groove (7), after the number of turn of intact designing institute regulation, this line is cross over second groove (2) continuously from the 7th groove, between second groove (2) and the 8th groove (8), after the equal number of turn that winds the line between intact first groove (1) and the 7th groove (7), from the 8th groove, be cross in the 15 groove again, between the 15 groove (15) and the 9th groove (9), after the equal number of turn that winds the line between intact first groove (1) and the 7th groove (7), from the 9th groove, be cross in the 16 groove again, between the 16 groove (16) and the tenth groove (10), after the equal number of turn that winds the line between intact first groove (1) and the 7th groove (7), the tail end of winding coil comes out from the tenth groove, is the tail end of second tap winding; The tap top of the 3rd speed governing winding coil is at first groove, method for winding is identical with the method for first speed governing winding, coiling between first groove (1) and the 7th groove (7), after the number of turn of intact designing institute regulation, this line is cross over second groove (2) continuously from the 7th groove, between second groove (2) and the 8th groove (8), after the equal number of turn that winds the line between intact first groove (1) and the 7th groove (7), from the 8th groove, be cross in the 15 groove again, between the 15 groove (15) and the 9th groove (9), after the equal number of turn that winds the line between intact first groove (1) and the 7th groove (7), from the 9th groove, be cross in the 16 groove again, between the 16 groove (16) and the tenth groove (10), after the equal number of turn that winds the line between intact first groove (1) and the 7th groove (7), the tail end of winding coil comes out from the tenth groove, is the tail end of the 3rd tap winding.This traditional winding mode and the distribution of winding are well-known.This tap debud mode is from the coil centre tap, and tapping line and intercoil connection intersect many mutually, easily causes winding interturn short-circuit; Because several taps are coiling separately, the coiling in the same groove is discontinuous, and the height of electric motor winding end is higher around intact, during the electric motor winding end shaping, easily causes the winding broken string; During coiling, several taps are returned again several times by same operation, and are consuming time many.
Summary of the invention
It is few to the purpose of this invention is to provide a kind of intercoil connection, utilizes intercoil connection to draw motor windings as the electric machine speed regulation tap line, has reduced the intersection of winding wire, and the turn-to-turn voltage of auxiliary winding obviously reduces, and has significantly reduced the winding interturn short-circuit possibility; Improve reliability of products and life-span, do not had other tap line, the winding overhang continuous and compact, the end size of winding is controlled, has reduced broken string during shaping; The step preface of coiling has reduced 1/3rd, and manufacturing process obtains simplifying the tapping mode of speed regulation of the alternating current motor of enhancing productivity.
In order to achieve the above object, the present invention realizes like this, it is a kind of method for winding of AC electrical machine stator, comprise the stator channel-section steel and be located at coiling on the stator channel-section steel, it is characterized in that: the number according to designing requirement and winding is selected the groove number of stator channel-section steel and the span of each winding, selected first groove of being convenient to wind the line is as the tap top of first winding coil on the stator channel-section steel, select first dead slot that is spaced apart N with first groove counterclockwise or clockwise according to designing requirement then, N is less than 1/2nd of the groove number of stator channel-section steel, coiling first winding coil between first dead slot of first groove and N with interval, the number of turn of pressing the designing institute regulation is behind intact first group of coil, this coiling again from first dead slot stride counterclockwise or clockwise around to interval for after second dead slot of N+2, this coiling in second dead slot, stride clockwise or counterclockwise around to interval in the 3rd dead slot of N, the number of turn by the designing institute regulation is finished second group of coil-winding, this line more counterclockwise or be cross over interval for the 4th dead slot of N+1 between up time from the 3rd dead slot, line between the 3rd dead slot and the 4th dead slot forms article one intercoil connection, this coiling of passing a bridge is cut off, one end is the tap tail end of first speed governing winding, the other end is as the tap top of second speed governing winding coil, it is in the 5th dead slot of N that second speed governing winding coil is wound on the 4th dead slot with interval counterclockwise or clockwise, the method that repeats first winding coil is determined under the cross-over connection dead slot of coiling at the beginning, by that analogy.
The present invention's advantage compared with prior art is: adopt this new tap mode to wind the line, intercoil connection is exactly a tap line, draws motor windings as the electric machine speed regulation tap line, has reduced the intersection of winding wire, the turn-to-turn voltage of auxiliary winding obviously reduces, and has significantly reduced the winding interturn short-circuit possibility; Improve reliability of products and life-span, do not had other tap line, the winding overhang continuous and compact, the end size of winding is controlled, has reduced broken string during shaping; The step preface of coiling has reduced 1/3rd, and manufacturing process obtains simplifying, and enhances productivity.Have, aspect electrical property, motor is when low speed again, and efficiency of motor also is improved.
