Description
Technical field
The present invention is related to a kind of stator winding insulation system for fitting in two stator tooths, refers in particular to one kind and is arranged at horse
Up to stator and include the stator winding insulation system for fitting in two stator tooths of hierarchic structure.
Background technology
All the time, if the induction conductivity of motor is all the main flow of electric rotating machine, for a long time because it is practical with it is firm resistance to
With and obtain the favor of people, quite crucial role is all play in process industry or people's livelihood industry so that people
Life it is inseparable with electric rotating machine.Motor is a kind of device that electric energy can be efficiently converted into mechanical energy, nearly several centuries,
Motor industrial boom, such as greatly to the generator in power plant, the vibrations motor as low as in mobile phone is all motor work
The product of industry.The principle that motor can convert electric energy to mechanical energy is the Ampere's law in the equation group of Maxwell, is led
Electromagnet can be formed because of magnetic field corresponding to Ampere's law produces by entering the coil of electric current, and electromagnet will connect in fixed magnetic field
It is continuous to rotate, it is able to convert electric energy to kinetic energy.
For structure, vital role is played the part of in the coiling inside motor, and in order to effectively improve power, it can set
The coil of very more numbers of turn, however, due to that would generally be provided with multiple teeth portion inside a motor, and coil be then wound in it is each
Need to keep being electrically insulated just not having the generation of short circuit phenomenon in teeth portion, therefore between each coil, relative limits coil
The number of turn, to avoid coil short and cause power to reduce, or even electric wire is cocked off because of motor failure.
Fig. 1 and Figure 1A are referred to, Fig. 1 is the diagrammatic cross-section for the motor stator for showing prior art, and Figure 1A is display Fig. 1
Partial enlarged drawing.As illustrated, a motor stator PA100 includes multiple stator tooth PA1 (one is only indicated in figure), Duo Geru
The insulation system PA2 (one is only indicated in figure) and multiple coiling PA3 (one is only indicated in figure) for the groove paper that insulate.Wherein, respectively
Stator tooth PA1 has an a tooth body PA11 and tooth boots PA12, and stator tooth PA1 interlinks and makes tooth body PA11 and tooth
A winding space PA200 is formed between boots PA12.While multiple stator tooth PA1 are spliced, in tooth body adjacent two-by-two
In insulation system PA2 between PA11 and tooth boots PA12, to avoid coiling PA3 from directly contacting tooth body PA11 and tooth boots
PA12。
Wherein, as shown in Figure 1, in existing insulation system PA2, it is limited between tooth boots PA12 and tooth body PA11 folded
Angle B be not be 90 degree so that coiling PA3 is easily caused along slip side when being wound on tooth boots PA12 and tooth body PA11
Slided to L1, L2 and winding displacement is not easy.
Referring to Fig. 2, Fig. 2 is the diagrammatic cross-section for another motor stator for showing prior art.As illustrated, to understand
The problem of certainly above-mentioned, prior art proposes links part in stator tooth PA1a tooth boots PA12a and tooth body PA11a, will be exhausted
Edge structure PA2a is designed as 90 degree of angle structure, but this structure can cause coiling PA3a reduction and reduce motor in the running
Power density, therefore, prior art still possesses improved space.
The content of the invention
In view of in existing insulation system, can generally cause coiling amount to reduce and the problem of reduce power density.Edge this,
