Life-span.
As shown in figure 5, same first winding or same second winding are used for the winding slot into line on rotor core 1
111 and six winding slots 111 of span of the winding slot 111 for outlet.
As shown in figure 1, on the rotor neck position 400 and the diverter 4 be used for weld coil windings 3 position away from
It is 8～12mm from L.
Insulation tank paper is provided with the winding slot 111, the coil windings 3 are embedded in winding slot and by insulation tank paper
Encase.Slot wedge is provided with the notch of line embedding groove, the space constituted between each enamel-covered wire of coil windings is filled with insullac.
As shown in fig. 6, the output end of the motor shaft 2 is followed successively by light shaft part 23, Gewindefreistiche section 25 and thread segment
22, the Gewindefreistiche section 25 is arranged between light shaft part 23 and thread segment 22, and the end of the smooth shaft part 23 is provided with down
Corner structure 24.Such simple structure, it is easy to process, low cost, while the assembling of client's shaft coupling is simple, convenient, motor shaft output
The light shaft part 23 at end and the light bore portion of client's shaft coupling front end, are designed to interference fits, are so easy to ensure motor at a high speed
The quality of fit and concentricity of shaft coupling and motor shaft during operation, hence it is evident that reduce the vibration of whole machine, and noise, improve expiring for client
Meaning degree, comfortableness and electrical machinery life.
Diverter 4 described above can be to improve the mechanical strength of diverter with ring structure 44, advantage is reinforced, greatly
Improve safety and the life-span of motor, meanwhile, using diverter 4 can increase between weld adjacent slot enamel-covered wire away from
From, it is to avoid short circuit, while coil is connected more preferably with diverter, the line embedding groove 42 on larger electric current, and diverter 4 can be born
It is 2 times of winding slot 111, reason is supply voltage to be added on armature winding by two carbon brush in geometric center lines,
Slightly seem, voltage is generally evenly distributed on each element.In fact the resistance of each element because the impact of coil induction reactance be to differ
Sample, but first around component resistance it is little, after around component resistance it is big, first around resistance it is little, according to Ohm's law U=IR, hold
Low by voltage, the commutator segment bar-to-bar voltage that it connects is also low, after around resistance it is big, the voltage for bearing is also high, the commutator segment of connection
Bar-to-bar voltage is also high, and the element of winding for just differing just produces current potential spark in motor operation；Current potential between each commutator segment
Pressure drop computing formula is:Up=2U/K, wherein U are supply voltage, and K is the piece number of diverter, can be drawn by formula, using piece
The many diverters of number, can obviously reduce the current potential pressure drop between commutator segment, reduce motor spark, improve electrical machinery life.
