Than the deficiencies of not only structure is more complex, but also anufacturability is poor.Being embodied in rotor punching is not overall structure, magnetic circuit
Design it is unreasonable, start it is ineffective.Two, some is made after magnetic shield cooperates with axis every magnetic, also with non-magnetic material
Motor shaft even is made with the stainless steel material of valuableness third is that magnetic flux distribution is uneven between each magnetic pole, motor to be caused to be made an uproar every magnetic
Sound and vibration are larger, and not only run stability is poor, but also service life is short.
Utility model content
The purpose of this utility model is to provide a kind of rotor structure of permanent-magnet synchronous of self-starting, above-mentioned to solve
Problem.
To achieve the above object, the utility model uses following technical scheme:
A kind of rotor structure of permanent-magnet synchronous of self-starting, including iron core and axis, iron core fixation are set on axis, axis
Positioned at the geometric center of iron core；Iron core includes several rotor punchings, and each rotor punching along the circumferential direction uniformly waits radians
Several conducting bar slots are provided with, conducting bar slot, which is formed by the rotor punching in circle, is provided with several pairs of magnet steel mounting grooves, each
Rotor punching is provided centrally with axis hole；Several rotor punchings sequentially coaxially fixed overlay forms iron core, and several magnet steel
Mounting groove is superimposed to form oblique pole magnetic slot.
Further, magnet steel mounting groove is arc-shaped, and several magnet steel mounting grooves encircle the geometric center of rotor punching
Setting；It is provided with and the matched magnet steel of its shape in the magnetic slot of oblique pole.
Further, conducting bar slot is opening conducting bar slot or silent conducting bar slot, is inlaid with conducting bar in conducting bar slot, conducting bar by copper or
Aluminium is made.
Further, the both ends of iron core are provided with mouse cage.
Further, rotor punching is an integral molding structure.
Compared with prior art, the utility model has following technical effect:
The utility model magnetic circuit uses the design of the oblique pole structure of magnet steel, and rotor punching is integral, and starting performance is good, fortune
