Description
Technical field
The utility model designs a kind of brushless motor accessory, specifically brushless single phase motor stator core.
Background technique
The pole shoe of its stator core of existing brushless single phase motor is arc-shaped symmetrically arranged, and the air gap between rotor is also
Symmetrically, it is identical to generate magnetic field for stator pole shoes therefore when electrical power, and can not drive rotor rotation, here it is industries to claim
Starting dead point；In order to allow brushless single phase electric motor starting, existing producer is generally in the pole shoe of brushless single phase motor stator core
Side sets a notch, make pole shoe two sides generate magnetic field it is of different sizes, come drive rotor rotation, but this setup its starting
Torque or very little, this results in brushless single phase motor on existing market there was only the small machine of small-power, the slow-speed of revolution, can only apply
Onto products such as phonographs, and it can not be applied to Power Tools Industries.
Utility model content
In view of the defect that existing brushless single phase motor stator core is latched in, technical problem to be solved in the utility model
It is: the problem of high-power single-phase brushless electric machine starting torque is small, difficulty in starting.
To achieve the goals above, one aspect according to the present utility model, the utility model are arranged by following technology
Apply realization: a kind of brushless single phase motor stator core, comprising: stator core ontology, the stator core ontology is by several
Silicon steel stamping sheets laminate fixed composition, which is characterized in that the silicon steel stamping sheets are in circular ring shape, the silicon steel stamping sheets of circular ring shape
It opens that there are four the locating slots of array setting on outer ring, prolongs on the silicon steel stamping sheets inner ring of circular ring shape to silicon steel stamping sheets center of circle direction
There are four stretching or more than four pairs of teeth, the extension side of each tooth is equipped with circular arc pole shoe, and each circular arc pole shoe of each tooth is mutual
It is not connected to but each circular arc pole shoe of each tooth constitutes central ring, the circular arc pole shoe is staged, low by a high boots body and one
Boots body is constituted.
Further, the tooth is four, opposite two-by-two between four teeth and four locating slots.
Compared with the prior art, the advantages of the utility model are: being increased by the setting of stepped circular arc pole shoe
Torque, and by forming the non-uniformity air gap of staged between circular arc pole shoe and rotor, permanent-magnet torque synthesis can be made to produce
Raw orientation detent torque, rotates rotor consequently facilitating rotor startup by orientation direction.

Specific embodiment
The utility model is described in detail below with reference to attached drawing and in conjunction with the embodiments.It should be noted that not rushing
In the case where prominent, the features in the embodiments and the embodiments of the present application be can be combined with each other.
In the description of the present invention, it should be understood that the instructions such as term "left", "right", " left side ", " right side "
Orientation or positional relationship is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of description the utility model and simplification
Description, rather than the device or element of indication or suggestion meaning must have a particular orientation, constructed and grasped with specific orientation
Make, therefore should not be understood as limiting the present invention.
Embodiment 1
Referring to Fig.1 and 2, brushless single phase motor stator core provided in this embodiment includes stator core ontology 101,
It is welded together if the stator core ontology 101 is laminated by dry plate silicon steel stamping sheets 102, wherein above-mentioned silicon steel stamping sheets 102
In circular ring shape, there are four locating slots 103,102 inner ring of silicon steel stamping sheets to extend internally for array filet on 102 outer ring of silicon steel stamping sheets
There are four the teeth 104 in array setting, and each tooth 104 is preferably opposite with a locating slot 103, and the opposite side of four teeth 104
Namely extend on side and be further fixed on circular arc pole shoe 105, four circular arc pole shoes 105 are not attached to together but four circular arc pole shoes
105 constitute central ring 106, are staged among above-mentioned circular arc pole shoe 105, that is to say, that by a high boots as preferred structure
Body 107 and a low boots body 108 are constituted, and are of coursed so-called high boots body 107 and are meant compared with low boots body 108 it closer to silicon
102 central point of steel stampings.
Brushless single phase motor stator core described in the present embodiment is since it uses stepped circular arc pole shoe 105, in this way
The non-uniformity air gap of staged is formed between circular arc pole shoe 105 and rotor, this structure can be such that permanent-magnet torque is synthetically produced
It orients detent torque and is rotated by determining direction, solve the problems, such as that the starting dead point of brushless single phase motor and torque are small, solve
The problem of certainly torque of high-power single-phase brushless electric machine starting is small, difficulty in starting, and with existing three-phase brushless motor than identical function
Controller at least can be less with the power tube of one third under rate.
The number for of coursing above-mentioned tooth 104 can increase, but increase minimum needs two every time and need two two
Carry out increase.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, the present invention can have various changes and variation.Within the spirit and principle of the utility model,
