Description
【Technical field】
It the utility model is related to a kind of magneto, and in particular to a kind of magneto with the tile-shaped magnet steel improved,
Belong to technical field of motors.
【Background technology】
It is well known that being equipped with magnet steel and iron core on the motor shaft of magneto, the length of these magnet steel and iron core is often
It is identical.And in order to detect the position of the motor shaft of magneto, it usually needs set Hall element to carry out inductive iron core.
However, during due to magnet steel and isometric iron core, disturbing pulse can be produced between magnet steel and iron core, so as to influence Hall member
The normal work of part；Meanwhile isometric magnet steel and iron core are also not easy to radiate.
Therefore, in order to solve the above technical problems, it is necessory to provide a kind of tile-shaped magnet steel with improvement of innovation forever
Magneto, to overcome the defect of the prior art.
【Utility model content】
To solve the above problems, the purpose of this utility model is to provide a kind of simple in construction, it is not easy to produce Hall element
Raw interference, and the magneto with the tile-shaped magnet steel improved that thermal diffusivity is good.
To achieve the above object, the technical scheme that the utility model is taken is：A kind of tile-shaped magnet steel with improvement is forever
Magneto, it includes stator, motor shaft, tile-shaped magnet steel, iron core, installing plate and Hall element；Wherein, the motor shaft passes through
The stator；The iron core is installed on motor shaft；The tile-shaped magnet steel is embedded in iron core；The length of the tile-shaped magnet steel is more than iron
The length of core, make to form a space between the end of iron core and two tile-shaped magnet steels；The installing plate is installed on the side of stator；Institute
Hall element to be stated to be installed on installing plate, it can be located at the side of iron core, and positioned at the top in space.
The magneto with the tile-shaped magnet steel improved of the present utility model is further arranged to：The iron core surface is provided with
Dovetail groove；The tile-shaped magnet steel inserts dovetail groove, and is fixed on iron core.
The magneto with the tile-shaped magnet steel improved of the present utility model is further arranged to：The tile-shaped magnet steel is at least
Provided with 4 pieces.
The magneto with the tile-shaped magnet steel improved of the present utility model is also configured to：The length of the tile-shaped magnet steel compared with
The long 5-10cm of length of iron core.
Compared with prior art, the utility model has the advantages that：Magneto of the present utility model has knot
Many advantages, such as structure is simple, is not easy to produce interference to Hall element, and easy for installation and thermal diffusivity is good.

Fig. 1 is the stereogram of the magneto of the tile-shaped magnet steel with improvement of the present utility model.
Fig. 2 is the installation stereogram of motor shaft of the present utility model, tile-shaped magnet steel and iron core.
Fig. 3 is the profile of the magneto of the tile-shaped magnet steel with improvement of the present utility model.
【Embodiment】
Refer to shown in Figure of description 1 to accompanying drawing 3, the utility model is a kind of permanent magnetism with the tile-shaped magnet steel improved
Motor, it is made up of several parts such as stator 1, motor shaft 2, tile-shaped magnet steel 3, iron core 4, installing plate 5 and Hall elements 6.
Wherein, the stator 1 is prior art, be will not be repeated here.The motor shaft 2 passes through the stator 1.
The iron core 4 is installed on motor shaft 2.The tile-shaped magnet steel 3 is embedded in iron core 4, and tile-shaped magnet steel 3 can be consolidated with glue
It is fixed, stainless ladle circle can also be wrapped in tile-shaped magnet steel 3 and the outside of iron core 4 and fixed.And the tile-shaped magnet steel 3 and iron core 4 are positioned at fixed
In son 1.Further, the surface of iron core 4 is provided with dovetail groove 9；The tile-shaped magnet steel 3 inserts dovetail groove 9, and is fixed on iron core
On 4, dovetail groove 9 can prevent that the centrifugation of tile-shaped magnet steel 3 is thrown out in rotation process；And the assembly method is easy for installation, and it is easy to
Change tile-shaped magnet steel 3.The tile-shaped magnet steel 3 can also increase according to the design needs at least provided with 4 pieces.
It is in place of greatest improvement of the present utility model：The length of the tile-shaped magnet steel 3 is more than the length of iron core 4, makes iron
A space 7 is formed between the end of core 4 and two tile-shaped magnet steels 3.Specifically, length of the length of the tile-shaped magnet steel 3 compared with iron core 4
Spend long 5-10cm.
The installing plate 5 is installed on the side of stator 1.The Hall element 6 is installed on installing plate 5, and it can be located at iron
The side of core 4, and positioned at the top in space 7.The Hall element 6 is capable of the position of inductive iron core 4, for detecting motor shaft 1
Position.
The design principle of the magneto of tile-shaped magnet steel of the present utility model with improvement is as follows：Due to tile-shaped magnet steel 3
Length be more than iron core 4 length, caused disturbing pulse is located in space 7 between tile-shaped magnet steel 3 and iron core 4, will not be to sky
The Hall element 6 of the top of gap 7 produces interference, ensure that Hall element 6 can accurately detect the position of motor shaft 1；Meanwhile by
Presence in space 7, motor shaft 1 can produce wind when rotating, so that the thermal diffusivity of motor is good.
Embodiment above is only the preferred embodiment of this creation, all in this wound not to limit this creation
Any modification, equivalent substitution and improvements for being done etc. within the spirit and principle of work, should be included in this creation protection domain it
It is interior.
