Surface-mount type permasyn morot at rotor surface；The third is the Embedded permasyn morot of permanent magnet portion.Mesh
Before, of home make magneto mostly is built-in magnetic line structure, its simple in construction, and process implementing is the most ripe, and domestic have not
The magneto manufacture of built-in structure is all known a thing or two by few producer.For comparing interior permanent magnet machines, surface-mount type permanent magnetism
Its radial direction effective air gap of motor is relatively big, and armature-reaction is less, and field waveform and current-voltage waveform aberration rate are little, vibration noise
Function admirable, the external magneto such as Jeumont S. A. of France, Siemens research and development is surface-mount type magnetic structure, state
Interior high-performance speed governing magneto newly developed mainly uses surface-mount type magnetic structure.
Summary of the invention
This utility model purpose be to provide a kind of simple in construction, cheap, be suitable to produce in enormous quantities and ensure that electricity
Speed governing that machine is good and the surface-mounted permanent magnet machine structure of operational reliability.
Surface-mounted permanent magnet machine structure, including stator core and the stator winding that is connected with stator core, its stator core
And arranging rotor core between axle, be respectively provided with magnet steel, without latitude band between rotor core and stator core, rotor core is horizontal
Both sides are respectively provided with rotor end plates, and rotor end plates arranges self cooling centrifugation blade；Rotor core is arranged axially adjacent to the both sides of axle
Rotor tension securing member.
If rotor core of the present utility model is made up of dry tablet rotor punching, uniform cloth on the outer peripheral face of described rotor punching
Put the magnet steel groove at 30 ° of angles, each magnet steel groove arranges the shoulder block of 2 °, each shoulder block arranges the groove of diameter 0.66mm；Rotor rushes
4 it are evenly arranged for setting between the circular hole controlling rotor moment of inertia, adjacent two circular holes on the magnetic line of force classification position of sheet
Put the hole, location for straining rotor tension securing member.
This utility model compared with prior art has the advantage that alinco assembled is convenient, it is not necessary to complicated work
True up standby；The fastening means on magnet steel surface is simple, and fastener material is common, cheap, is suitable to produce in enormous quantities；The side of design simultaneously
Method has taken into account the built-in and respective advantage of surface-mount type, preferably ensure that the performance of magneto.Especially ensureing motor
On the premise of efficiency, power factor, synchronizing capacity of moving into and overload capacity, it is thus achieved that higher ac-dc axis inductance ratio, thus
Ensure that speed adjusting performance and operational reliability that motor is good.
