The syndeton of piecemeal stator motor winding
The present invention relates to a kind of fan class motor, relate in particular to the syndeton of the piecemeal stator motor winding that the stator winding of motor uses.
The piecemeal stator motor mainly is the interior winding efficiency problem of separating determinant.In the monoblock when stator winding maximum speed be 1000r/min, and outward around stator winding speed 3000r/min; Slow in the monoblock around stator winding speed, and tapping ratio is more, inconvenient operation.
Summary of the invention
The objective of the invention is to consider the problems referred to above and provide a kind of can mass production, it is convenient to have a coiling, threading speed is fast, master, pair winding combination operation simultaneously conveniently, design ingeniously, serviceability is good, the syndeton of convenient and practical piecemeal stator motor winding.
In order to achieve the above object, the present invention is achieved in that it is a kind of syndeton of piecemeal stator motor winding, it is characterized in that comprising piecemeal stator, the drum stand more than two, first frock and second frock more than four; Described piecemeal stator evenly distributes along circumference, and described drum stand is trapped among the outside of first frock, and the outside of drum stand cooperates with the piecemeal stator, is provided with crossed beam trunking on drum stand; Described first frock is cylindric, be provided with the draw-in groove that cooperates with rotating shaft in the inboard of first frock, be provided with the locating groove more than four in the outside of first frock, the groove shoulder of described drum stand both sides is arranged in two adjacent locating grooves, and adjacent two locating grooves are located drum stand; Described second frock is cylindric, and the second frock suit is fixed on outside each piecemeal stator.
Be provided with the outer arc of the outside protrusion concentric in described first frock outside, the elastic compression devices that groove shoulder and locating groove are close to is installed on the outer arc wall of first frock with it.
On described second frock, be provided with and make itself and each piecemeal stator elastic compression devices that is close together.
Be arranged with end cap outside described each piecemeal stator, described end cap and each piecemeal stator closely cooperate.
The present invention's advantage compared with prior art is: because first frock is connected and fixed drum stand, make the method that can adopt the external rotor coiling of internal rotor stator, winding efficiency has been improved more than 3 times; Have wiring of internal rotor stator and the few characteristics of tap mode simultaneously, can reduce joint quantity, improved production efficiency; This invention design is ingenious, and serviceability is good, and is convenient and practical.

Below in conjunction with drawings and Examples the present invention is done further detailed description:
To shown in Figure 7, it is a kind of syndeton of piecemeal stator motor winding as Fig. 1, and characteristics of the present invention are piecemeal stator 4, drum stand 3, first frock 1 and second frocks 5 more than two that comprise more than four; Described piecemeal stator 4 evenly distributes along circumference, and described drum stand 3 is trapped among the outside of first frock 1, and the outside of drum stand 3 cooperates with piecemeal stator 4, is provided with crossed beam trunking 32 on drum stand 3; Described first frock 1 is cylindric, be provided with the draw-in groove 12 that cooperates with rotating shaft in the inboard of first frock 1, be provided with the locating groove 11 more than four in the outside of first frock 1, the groove shoulder 31 of described drum stand 3 both sides is arranged in two adjacent locating grooves 11, and adjacent two locating grooves 11 are with drum stand 3 location; Described second frock 5 is cylindric, and second frock, 5 suits are fixed on outside each piecemeal stator 4, makes each piecemeal stator 4 work in coordination fixing.
During coiling, two drum stands 3 and first frock 1 are formed the external rotor stator of two or more external tooths, after coiling on the coil winding machine, form the main winding stator or pay the winding stator, shown in Fig. 3,4; When leading, paying the winding coiling, enamelled wire is placed on crossed beam trunking 5(32 when coiling) in; The main winding stator inserts in opposite directions with paying the winding stator then, as Fig. 6, utilizes second frock 5 that the joining part of each piecemeal stator 4 is bound up, and perhaps is welded to connect, and perhaps puts into frock, directly is pressed into end cap, makes it to link together by end cap.The invention belongs to the internal rotor stator, but it has used the external rotor method for winding, made winding efficiency improve more than 3 times; Guarantee wiring of internal rotor stator and tap mode simultaneously, can reduce joint quantity, improved production efficiency; This invention design is ingenious, and serviceability is good, and is convenient and practical.
In the present embodiment, be provided with the outer arc 13 of the outside protrusion concentric in described first frock 1 outside, the elastic compression devices 2 that groove shoulder 31 and locating groove 11 are close to is installed on outer arc 13 walls of first frock 1 with it.On described second frock 5, be provided with and make itself and each piecemeal stator 4 elastic compression devices 6 that is close together.
In the present embodiment, as shown in Figure 7, be arranged with end cap 7 outside described each piecemeal stator 4, described end cap 4 closely cooperates with each piecemeal stator 4.During assembling, after each piecemeal stator 4 even distribution moulding, each piecemeal stator 4 can be welded into a monoblock stator, and then be pressed into end cap 7; Also end cap 7 directly can be pressed into the piecemeal stator, make each piecemeal stator 4 fixing, enter the next procedure that motor is made again.
