Abstract
A permanent magnetism motor comprises a rotor punching sheet formed by punching and molding a metal plate, and magnets of the rotor punching sheet. More than one magnet built-in groove and glue-pouring hole which are corresponding with the magnets are arranged on the rotor punching sheet, the magnets are inserted inside the magnet built-in grooves and integrally glued with the punching sheet to form a permanent magnetic rotor jointly. The magnets are radially arranged along the punching sheet inner bore of the rotor punching sheet, each magnet is a tangential magnetizing structure, number of poles of the magnets is 2 to 20 pairs, and the punching sheet inner bore is gear-shaped or flower-shaped. Through adding the magnet built-in grooves, the magnets are radially arranged along the rotor punching sheet, gaps between the magnets and the rotor punching sheets are fixed through glue pouring; through adding a magnetism-blocking magnetic bridge, magnetic flux saturation of the part can be realized, and magnetic leakage can be restricted; weak punching sheet mechanical strength caused by under dimension can be avoided through a reasonable design, the service life of punching die will not be influenced; a ferrite permanent magnet can be used for substituting the prior neodymium iron boron permanent magnet completely through a reasonable electromagnetic design, and costs can be reduced.
Description
Technical field
The utility model relates to a kind of magneto.
Background technology
In the family expenses magneto, ferrite permanent-magnet and rubidium iron boron permanent magnetism have the most widely to be used.For ferrite permanent-magnet, rubidium iron boron permanent magnetism is owing to have higher coercive force, and lower remanent magnetism performance is superior to ferrite.But in recent years, owing to the protection of countries in the world to rare earth material, China had also strengthened the regulation and control to rare earth material, caused the Rb-Fe-B material substantial appreciation of prices, caused production cost to increase, and had restricted the development of enterprise simultaneously.Therefore, in certain fields,, realize that ferrite permanent-magnet replaces the problem that used rubidium iron boron permanent magnetism is the positive solution of each enterprise's needs at present through rational Electromagnetic Design.
The utility model content
The purpose of the utility model aims to provide a kind of simple and reasonable, with low cost, easy to process and can improve the power of motor and the magneto of overload capacity, to overcome weak point of the prior art.
A kind of magneto by this purpose design; The rotor punching and the magnet thereof that comprise the metal plate punching moulding; Its architectural feature is that the corresponding magnet of said rotor punching is provided with built-in groove of more than one magnet and glue filling opening; Magnet is inserted in the built-in groove of magnet, and with punching be the setting of one encapsulating, constitute a p-m rotor jointly.
To setting, magnet is the cutting orientation magnetizing structure to said magnet along the punching internal orifice dimension of rotor punching, and the number of poles of magnet is that 2-20 is right; The punching endoporus is profile of tooth or flower shape.
The built-in groove of said magnet is provided with clearance position, to satisfy the installation site of magnet; This clearance position is arch or arc.
Be provided with between the built-in groove of said adjacent magnet at a distance from the magnetic magnetic bridge, be horn-like or funnel-form at a distance from the magnetic magnetic bridge, separated magnetic magnetic bridge is a miner diameter end near an end of punching endoporus; The angle C of miner diameter end and bigger diameter end is 95 °-145 °.
Said length dimension A at a distance from the magnetic magnetic bridge is 1-1.3mm, and width dimensions B is 1.6-1.8mm.
The utility model guarantees that through setting up the built-in groove of magnet magnet radially is provided with along rotor punching, and magnet and rotor punching gap adopt the mode of encapsulating to fix, and constitute a p-m rotor jointly; This position magnetic flux is reached capacity and play the effect of restriction leakage field at a distance from setting up of magnetic magnetic bridge, reasonably design can also avoid this undersized and cause the punching bad mechanical strength, influences the useful life of punch die.
The utility model its have simple and reasonable, assembling is easy and be convenient to the characteristics of processing; And cooperate effect, can use ferrite permanent-magnet that higher air gap flux density is provided, and guarantee that magnetic field evenly distributes at a distance from magnetic magnetic bridge restriction leakage field; In certain fields; Let ferrite permanent-magnet through rational Electromagnetic Design, can replace used rubidium iron boron permanent magnetism fully, reduce cost.
