Abstract
The invention discloses a stator winding of a permanent magnet brushless coreless motor. The stator winding is formed by stacking and connecting a first-layer single-phase winding disc, a second-layer single-phase winding disc and a third-layer single-phase winding disc; the single-phase winding discs are connected in a star form. The stator winding is in the chain-connected triple-layer stacked design, a sector coil is adopted so that length of an effective side of the stator winding is increased, air space is lessened, utilization rate of magnetic energy is increased, and electromagnetic torque of the motor is increased; in addition, the stator winding is in a coreless plane structure, cogging torque and iron loss are eliminated, axial size of the motor is decreased, stator weight is decreased, and power intensity of the motor is increased.
Description
Technical field
The invention belongs to brushless, permanently iron-core less motor technical field, particularly relate to a kind of stator winding of brushless, permanently iron-core less motor.
Background technology
Tradition permanent magnet DC motor adopts silicon steel sheet as stator core, and axial dimension is large, and cogging torque and stator iron loss, moment of inertia is large, response speed is slow, commutation ability is undesirable.And motor made by this kind of winding dish adopts is axial magnetic field, increase substantially power density and torque volume ratio; Adopt novel winding technique and polymer composite high voltage precision compression molding process, effectively reduce winding copper loss; Do not use silicon steel sheet as fixed core material, decrease magnetic damping, reduce driving power, decrease iron loss pyrotoxin.There is noise little high with efficiency, can the advantages such as high voltage be adopted, so have very wide application.
Summary of the invention
In order to solve the problems of the prior art, the object of this invention is to provide a kind of stator winding of brushless, permanently iron-core less motor.
In order to realize technique scheme, the present invention adopts technical scheme as described below:
A stator winding for brushless, permanently iron-core less motor, this stator winding is superposed by the single-phase winding dish of ground floor single-phase winding dish, the second layer single-phase winding dish and third layer to connect to form, and three layers of single-phase winding dish adopt star connection.
Further, any two-layer single-phase winding rim of three layers of single-phase winding dish counterclockwise differs certain angle each other.
Further, ground floor single-phase winding dish, the second layer single-phase winding dish and the single-phase winding dish of third layer are all formed according to range winding switching by several coils.
Further, the coil forming the single-phase winding dish of every one deck is sector structure.
Owing to adopting technique scheme, the present invention has following superiority:
Stator winding of the present invention adopts the design of chain type connection three layers of superimposed type, cuts the length adopting sector (-shaped) coil to add winding effective edge, reduces air gap, strengthens magnetic energy utilization rate, increases the electromagnetic torque of motor; In addition, this stator winding is iron-core-free planar structure, eliminates cogging torque and iron loss, reduces motor axial dimension, alleviates stator quality, improves the power density of motor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1-coil; The single-phase winding dish of 2-ground floor; The single-phase winding dish of the 3-second layer; The single-phase winding dish of 4-third layer; 5-inlet wire.
Embodiment
As shown in Figure 1, a kind of stator winding of brushless, permanently iron-core less motor, this stator winding is superposed by the single-phase winding dish 4 of ground floor single-phase winding dish 2, the second layer single-phase winding dish 3 and third layer to connect to form, and three layers of single-phase winding dish adopt star connection.
Any two-layer single-phase winding rim of described three layers of single-phase winding dish counterclockwise differs certain angle each other.
Ground floor single-phase winding dish 2, the second layer single-phase winding dish 3 and the single-phase winding dish 4 of third layer are all formed according to range winding welding by several coils 1, and described coil is fan-shaped, also can be square, trapezoidal or other geometry.
In addition, it should be noted that, this stator winding is iron-core-free plane winding, is to connect and compose three-phase windings by three layers of single-phase winding dish superposition; When three layers of single-phase winding dish adopt star connection to connect, the leading-out terminal of three single-phase winding dishes is linked together as asterism, now three single-phase winding dishes remain three inlet wires, are drawn by the line of three inlet wire different colours as the inlet wire 5 of motor, the winding dish after connecting is put into particular manufacturing craft and suppresses, reduce the thickness of winding dish, detect between winding and whether there is short circuit, the problems such as electric leakage, finally adopt special macromolecular material moulding by casting, by three layers of winding parcel, it is made not expose.
