Abstract
The utility model discloses a lower puncher pin structure which enables a magnetic shoe scalar magnetic potential to show sine waves. The lower puncher pin structure which enables the scalar magnetic potential to show the sine waves is characterized in that the lower puncher pin structure comprises a puncher pin handle made of magnetic conductive materials; the two ends of the puncher pin handle are respectively horizontal end surfaces; a puncher pin end surface made of magnetic conductive materials is inset in one end of the puncher pin handle; a welding end of the puncher pin end surface is a horizontal surface; the other end of the puncher pin end surface is an arc surface which is recessed inwardly; and the distance between the central section to the bottom section of the arc surface is 1-1.5mm. The lower puncher pin structure which enables the magnetic shoe scalar magnetic potential to show the sine waves of the utility model is reasonable in structural design; since the puncher pin end surface made of the magnetic conductive materials is inset in one end of the puncher pin handle and the thickness of the puncher pin end surface made of the magnetic conductive materials is under certain restrictions so as to satisfy requirements for forming a magnetic field, and the magnetic shoe, of which a surface filed shows the sine waves, can be manufactured after processing through the puncture pin end surface, so that demands of household electrical appliance type frequency conversion BLDC brushless direct current motors are satisfied.
Description
Technical field
The utility model relates to a kind of low punch structure, relates in particular to a kind of magnetic shoe mark magnetic that makes and is sinusoidal wave low punch structure.
Background technology
Required in order to make electric efficiency reach client at present, magnetic shoe whole table is sinusoidal wave distribution has become needs, particularly, on household appliances frequency conversion BLDC brshless DC motor, for preparation table field is sinusoidal wave magnetic shoe, it need to carry out to low punch structure the improvement of magnetic circuit and parameter.
Utility model content
The purpose of this utility model is the deficiency in order to make up prior art, provides a kind of magnetic shoe mark magnetic that makes to be sinusoidal wave low punch structure.
The utility model is achieved through the following technical solutions:
A kind of magnetic shoe mark magnetic that makes is sinusoidal wave low punch structure, it is characterized in that: include the punch-holder shank that adopts permeability magnetic material to make, the two ends of described punch-holder shank are respectively horizontal end face, its one end is inlaid with the punch end face that adopts non-magnet_conductible material to make, the welding ends of described punch end face is horizontal plane, the other end is the arcwall face caving inward, and the middle part of described arcwall face is 1-1.5mm far from the distance of bottom.
The utility model has the advantages that:
The utility model reasonable in design, by being inlaid with in the horizontal end of punch-holder shank the punch end face that non-magnet_conductible material is made, and in order to meet the requirement that forms magnetic field, the thickness of its non-magnet_conductible material punch end face will have certain restriction, use this punch end face just can be processed into table and be sinusoidal wave magnetic shoe, thereby meet the demand of household appliances frequency conversion BLDC brshless DC motor.
