Description
Technical field
The utility model belongs to motor stator technical field more particularly to a kind of excitation electromotor stator.
Background technique
Motor stator is the important component of the motors such as generator and starter.Stator is motor part and parcel.
Stator is made of stator core, stator winding and base three parts.The main function of stator is generation rotating excitation field, and rotor
Main function is in rotating excitation field by magnetic force line cutting and then generation (output) electric current.China current motor accessory component market
It is distributed southeastern coast and Yangtze River Delta.Stator winding refers to the winding being mounted on stator, that is, is wound on stator
The copper wire in face.Winding is the general designation that a phase or entire electromagnetic circuit are made of multiple coils or coil group.Motor is according to coil
The shape of coiling is different from embedded wire laying mode, can be divided into centralized and distributed two class.The coiling of centralized winding and be embedded in
It is fairly simple, but efficiency is lower, and runnability is also poor.The current AC electrical machine stator overwhelming majority be all application distribution formula around
Group, according to different machines, model and coil it is embedding around process conditions, motor respectively designs using different winding types and rule
Lattice.
Motor winding inserting method has: three kinds of Three-phase Single-layer Windings, three-phase Double Layer Winding and the single, double layer winding of three-phase.
The common pattern of Three-phase Single-layer Windings has equal in width formula, staggered form, concentric type etc., and different patterns has different embedding rules, but
Basic embedding rule is identical.Empty slot buttonhole selvage method embedding can be used in single layer Concentrical winding, Concentrical winding, but in reality
In operation for convenience, whole embedding method is generallyd use, i.e. layering embedding.Although this whole embedding method simple process, in order to which shaping needs
It wants, each layer tip lengths can not be equal, thus triphase parameter is unbalanced, affects electric property.Three-phase Double Layer Winding, three-phase
Large and middle size motor generallys use Double Layer Winding embedding, and coil is overlapping.The single, double layer winding of three-phase be by stacked short distance winding develop and
A kind of winding type for the better performances come.It is that the upper and lower level of the double-deck lap winding is merged into a single layer with phase effective edge is big
Coil side, so, coil total number of turns is fewer than Double Layer Winding, embeds the wire convenient and time-saving.And short pitch can be used in coil, remains double
The advantages that layer short distance winding energy Eliminate highter harmonic, improvement electromagnetic performance is a kind of more advanced winding type.
Existing energized stator embedding, winding is single coil, after the entire embedding complete line of stator, then passes through connector for single coil
It connects.The production efficiency is lower, and since winding joint is relatively more, hidden danger of quality is bigger.
Application No. is CN201620601684.5, the applyings date are as follows: 20160616 titles are as follows: a kind of motor stator coil
The insulation system of winding and application its motor patent in, disclose a kind of insulation system of motor stator coil winding and answer
With its motor, the insulation system of the motor stator coil winding includes stator core, the end that is mounted on stator core
The coil windings insulate, being wound on overhang insulation and the stator lead-out wire being electrically connected with the end of a thread of coil windings, the stator
Insulating protector is arranged in the lower section of lead-out wire, and the insulating protector, which is covered on above coil windings, plays the role of electrical isolation, absolutely
Edge protector outer is equipped with flange and is covered on the side of the coil windings.
Summary of the invention
