Abstract
The utility model discloses a motor winding with simple manufacture arts for avoiding difficult of lower line when hard winding occurs more laces or less laces, a stator winding of which comprises a hard winding and a loose winging separately positioned on upper layer and down layer of a slot, wherein, the hard winding is a double-layer cascade winding, while the loose winding is a single-layer chain winding. The head or tail end of the same hard winding loop in the same phase is connected with the corresponding tail or head end of the loose winding loop of the same group.
Description
Technical field:
The utility model relates to a kind of motor, relates in particular to a kind of motor windings.
Background technology:
The stator winding of common variable-frequency motor adopts diffusing winding generally speaking, along with the low-pressure high-power motor is widely used in frequency control, when particularly the rated voltage of motor is 660V or 690V, loose winding because enameled wire coat is thinner, and impact resistance is poor, and winding is easy to damage, so stator winding need adopt hard winding, but because the power of motor is big and voltage is low, cause stator winding circle on the low side, be easy to occur the situation of the few circle of multiturn.As when the situation of the few circle of multiturn occurring, just have no idea to roll off the production line, a kind of method is deepened the stator grooved exactly, but the utilance of groove is very low, and undesirable, give in the design and brought very big difficulty.
The utility model content:
The purpose of this utility model provide a kind of give to roll off the production line when avoiding hard winding the few circle situation of multiturn to occur cause difficulty, the simple variable-frequency motor winding of manufacturing process.
The technical solution of the utility model comprises stator winding, and described stator winding comprises firmly, diffusing two cover windings, and hard winding equates with the sectional area of every circle conductor of diffusing winding.
The number of turn relation of described hard winding and diffusing winding satisfies: as every groove conductor number is m (m is an odd number), and then hard umber of turn is m-1, and diffusing umber of turn is 1.
Described hard winding is set to double-deck lap winding, and diffusing winding is set to individual layer chain type winding, the head of same group of hard winding coil of homophase/or tail end and tail of the corresponding same group of winding coil that looses with it/or head end be connected.
Described diffusing, hard winding is divided into upper and lower layer in the line embedding groove,
Hard winding connects motor down-lead, and winding and asterism loose.
The utility model has solved the difficulty that situation that the few circle of multiturn appears in hard winding is given design, rolled off the production line and bring well, and for design provides convenience, and technology simply is easy to make.
Description of drawings:
Figure is the utility model three-phase and quadrupole stator winding structure schematic diagram.
Embodiment:
As shown in the figure, hard winding Y is double-deck lap winding, the winding S that looses is an individual layer chain type winding construction, and hard winding Y is embedded in bottom land during rule, and the winding S that looses is embedded in notch, and the hard winding Y of every circle equates as far as possible with the sectional area of wire of diffusing winding S.Roll off the production line, must guarantee that hard winding Y is identical with the sense of current of diffusing winding S in each groove during wiring.Because it is bigger that former circles of winding are subjected to rush of current, and the paint film of hard winding Y is thicker, and anti-rush of current power is strong, so adopt hard winding Y to connect motor down-lead, winding S and asterism loose.Each mutually every group winding S coil that looses with the hard on the same group concrete wiring of winding Y coil of corresponding homophase with it is: a1 meets d1, a2 and connects that d2, a3 meet d3, a4 meets d4; B1 meets e1, b2 and connects that e2, b3 meet e3, b4 meets e4; C1 meets f1, c2 and connects that f2, c3 meet f3, c4 meets f4; Each phase leading-out terminal U
