The wiring mode is as follows: the star and triangle (Delta) windings are arranged and wired in the same slot of the stator. The connection wiring mode of the sine winding adopts an extended triangle and a star triangle. The utility model has the advantages of energy-conserving effect is high, and is average energy-conserving 8.75%, motor working property are stable, are a good project of being worth promoting.
Description
The utility model relates to a kind of Y-△ mixing wiring energy-saving motor, specifically is meant the improvement of common electric machine winding connection mode, belongs to electric motors.
China's common motor product, capacity be at the motor of 3.0kw-11kw, the mode of its three phase winding generally adopt the individual layer staggered form, single stacked, singly connect formula, concentric type etc.The motor of this winding, it is very strong to use high order harmonic component, directly influence the service behaviour of motor, and power consumption is big, in order to improve the operating efficiency of motor, Chinese patent CN2084249U discloses a kind of " equal-turn type Y-△ mixing wiring winding ", this scheme is utilized existing positive chorded winding principle, organize mutually for two with the every phase of former motor, make four groups mutually into, the number of turn of each coil is identical with the specification of lead, and the way of Y connection is the twice of delta connection, this technical scheme, for transforming J02 and JS series motor, the service behaviour that improves motor provides technical scheme preferably, but in the high order harmonic component of thoroughly eliminating motor itself, improves the energy-saving effect aspect and also have certain defective.
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and a kind of high Y-△ mixing wiring energy-saving motor of high order harmonic component, energy-saving effect that can thoroughly eliminate motor is provided.
The purpose of this utility model is achieved in that the utility model is the Y-△ mixing wiring energy-saving motor of the mode of connection of the positive chorded winding of reconfiguration on three phase windings of common electric machine, it is characterized in that being respectively equipped with in the wiring groove of stator star (Y) winding, two kinds of modes of connection of triangle (△) winding, the mode of connection of the positive chorded winding of reconfiguration is to utilize every phase winding of star part and the every phase winding of triangular portions to arrange wiring in the same groove of stator.
The utility model is described in further detail below in conjunction with (accompanying drawing) embodiment:
Fig. 1 is the structural representation of the utility model Y-△ mixing wiring.
Wire laying mode among the figure is two kinds of wiring modes of connection of star (Y) winding and triangle (△) winding, embodiment of the present utility model is that 12 utmost points of 4 grade of 36 groove are organized motor mutually, the upper strata of first groove is that star (Y) connects AY1, lower floor is that triangle (△) connects A △ 1, the upper strata of the 4th groove is that star (Y) connects BY2, lower floor is that triangle connects B △ 2, once arrange in this order, in order to eliminate high order harmonic component, positive chorded winding of the present utility model is to utilize the winding of the every phase of star part and the every phase winding of triangular portions to arrange the wiring wiring in the same groove of stator, A △ 1 is for going into head among the figure, and A △ 2 is for lifting one's head; B △ 1 is for going into head, and B △ 2 is for lifting one's head; C △ 1 is for going into head, and C △ 2 is for lifting one's head; AY1 is for going into head, and AY2 is for lifting one's head; BY1 is for going into head, and BY2 is for lifting one's head; CY1 is for going into head, and CY2 is for lifting one's head two kinds on the connected mode employing extend-triangle of whole positive chorded winding and star triangle.The mode of connection of extend-triangle is for being connected into the triangular portions winding triangle respectively, star part winding connects into a star, then three tail heads of star winding are connected to three tops of delta windings, the first head of star are drawn be connected to power supply; The leg-of-mutton connected mode of star is: respectively the triangular portion sub-winding is connected into a triangle, three of being connected into after the star star of star winding enter the top that head is connected on delta windings respectively, then star are partly drawn tap and are connected to power supply.
The utility model be applicable to the individual layer staggered form, single stacked, singly connect the 3.0kw-11kw motor of formula, four kinds of winding modes of concentric type.
Positive chorded winding of the present utility model is to utilize every phase winding of star part and the every phase winding of gable to arrange wiring in same groove to be connected, this star (Y), triangle (△) mixes the mode of connection, eliminated the phase difference of the 30 ° of electrical degrees of induced potential in star winding and the delta windings two parts phase winding, be to be connected into extend-triangle and star triangle electrical degree when all eliminating 30 ° of two parts winding currents, eliminate star part and triangular portion phase-splitting electromotive force 120 ° of electrical degrees of mutual deviation each other each other, eliminate star part and 30 ° of electrical degrees of the corresponding electromotive force of gable, so just eliminated motor five times for a full due, seven inferior a series of high order harmonic component magnetic potentials.
The utility model is owing to having eliminated higher hamonic wave, so the utlity model has compared to existing technology the energy-saving effect height, average energy-conservation 8.75%; The motor operation stable performance, noise is little, the advantages such as operating efficiency height. Because the utility model has been opened up energy-conservation new way, so if apply the utility model in China, its economic effect will be very considerable.
