Description
[technical field]
The utility model is a kind of fixture of motor magnet.
[background technology]
The fixture of existing motor magnet generally all is the cylindrical shell of a hollow, on the cylindrical shell inwall of hollow, be arranged with a plurality of magnet, between each magnet with a pillar at interval and the location, install rotor in the cylindrical shell more afterwards, behind the epitrochanterian coil power supply, will realize rotating, but owing to be to locate between a plurality of magnet with a pillar, in cylindrical shell, each magnet is clung, in case motor operation is of a specified duration like this, it is loosening magnet just may to occur, and serious also coming off of magnet can occur, will entering in the rotor of magnet, thus damage motor even cause the accident.
[utility model content]
The utility model purpose is to have overcome deficiency of the prior art and fixture that the fixing motor magnet firm, simple in structure of a kind of magnet is provided.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposal:
A kind of fixture of motor magnet, it is fixed in the motor shell, it is characterized in that including the locating rack of the annular that can place magnet, on the locating rack of annular, evenly be provided with a plurality of spacers, on the inwall between the adjacent spaces post, be provided with inner sealer, described spacer and inner sealer form down positioning step, and the bottom of described magnet is installed and is placed on down on the positioning step, but also be provided with on the locating rack fixed magnet top on location structure.
The fixture of aforesaid a kind of motor magnet, it is characterized in that described locating rack is divided into locating rack and following locating rack, described upward location structure is that adapt with magnet top and identical with a following positioning step structure last positioning step, following positioning step is located at down on the locating rack, last positioning step is located on the locating rack, and last locating rack and following locating rack are connected and fixed.
The fixture of aforesaid a kind of motor magnet, it is characterized in that the described location structure of going up includes the backboard that is located at the spacer rear wall, each extension is bent with barb in each both sides, backboard top, described magnet bottom is stuck in down on the positioning step, and magnet top is stuck between the barb on the adjacent backboard and by barb and hooks.
The utility model compared with prior art has following advantage: owing to be arranged at intervals with a plurality of spacers on locating rack, on the inwall between the adjacent spaces post, be provided with inner sealer, magnet is placed between the spacer, inner sealer blocks the magnet bottom, make the magnet bottom can not enter the inside of motor, locating rack also is provided with the last location structure that magnet top is fixing, the upper and lower part of magnet all is fixed like this, make magnet firm, can not occur coming off, even if just in case occur coming off, magnet does not go out to enter in the rotor yet and goes, and can not cause the accident.Have this fixture structure simple again, cost is also low.
[description of drawings]
Fig. 1 is the exploded view of the utility model embodiment one;
Fig. 2 is the exploded view of the utility model embodiment two.
[embodiment]
Below in conjunction with accompanying drawing the utility model is described in detail:
Embodiment one, a kind of fixture of motor magnet, it is fixed in the motor shell 1, include the locating rack 3 that to place magnet 2, evenly be provided with a plurality of spacers 7 on the locating rack 3 of annular, be provided with inner sealer 8 on the inwall between the adjacent spaces post 7, described spacer 7 forms positioning step 4 down with inner sealer 8, the bottom of described magnet 2 can be fixed on down on the positioning step 4, but also be provided with on the locating rack 3 fixed magnet 2 tops on location structure 5.
As shown in Figure 1, described locating rack 3 is divided into locating rack 31 and following locating rack 32, described go up location structure 5 be one that adapt with magnet 2 tops and with the identical last positioning step 6 of following positioning step 4 structures, following positioning step 4 is located at down on the locating rack 32, last positioning step 6 is located on the locating rack 31, last locating rack 31 and following locating rack 32 are connected and fixed, by following positioning step 4 and last positioning step 6 phase magnets, magnet 2 just is securely fixed on locating rack 31 and the following locating rack 32 very much like this, relocate frame 3 peripheries afterwards and will go up motor chassis, then rotor will be arranged in locating rack inside, rotor energising back just can realize rotating.
Embodiment two, as shown in Figure 2, what embodiment two and embodiment one were different is, the described location structure 5 of going up includes the backboard 51 that is located at spacer 7 rear walls, respectively be extended with barb 52 in each both sides, backboard 51 top, the bottom of described each magnet 2 is stuck in down on the positioning step 4, and the top of each magnet 2 is stuck between the barb 52 on the adjacent backboard 51 and by barb 52 and hooks.
