Description
Technical field
Magneto is the utility model is related to, especially a kind of permanent magnetism quadrupole three-phase synchronous generator.
Background technology
Magneto is widely applied at present, because rare earth permanent-magnetic generator has small volume, in light weight, power
The plurality of advantages such as greatly, efficiency high, temperature rise be low, are used in many generating occasions.But because rare earth material cost is very high, do not conform to
The design of reason, while wasting rare earth material, the cost of magneto is added again.
The content of the invention
The utility model is improved for the weak point of the above, releases that a kind of volume is smaller, and power density is higher,
Save rare earth material, a kind of lower permanent magnetism quadrupole three-phase synchronous generator of cost.
The technical solution of the utility model is:A kind of permanent magnetism quadrupole three-phase synchronous generator includes：Rotor core, permanent magnetism
Body 1, permanent magnet 2, gland, stator core, three-phase windings, axle, casing etc. form, it is characterised in that：Rotor core is by silicon steel sheet
Or steel strip stamping is stacked and formed, each magnetic pole rushes the dead slot for having W types, dead slot placed inside permanent magnet 1 and permanent magnet 2, permanent magnetism
The sectional dimension of body 1 is 25mm × 7.5mm, and the sectional dimension of permanent magnet 2 is 30mm × 7.5mm, rotor core（1）External diameter be
163.8mm, stator core are formed by silicon steel sheet punching press is stacked, internal diameter 165mm, external diameter 260mm, the wide 6.8mm of chi, and yoke is wide
30mm,
There are non-magnet material gland fixed permanent magnet 1 and a permanent magnet 2 in the both ends of rotor core, permanent magnet 1 and permanent magnet 2
Material is rare-earth Nd-Fe-B magnet steel, trade mark 45SH.
The utility model has the advantage of：Rotor uses the permanent magnet arrangement mode of W types, improves rotor flux density；
