Abstract
The utility model discloses a brushless electric motor rotor, including six magnet steel, rotor core, with the coaxial complex pivot of rotor core, have six magnet steel slot along rotor core's circumference surface equipartition, six magnet steel inlay respectively in six magnet steel slot, are equipped with bellied tooth portion between two adjacent magnet steel slot, division fluted on the top of tooth portion, interference fit has the pin in the recess. The utility model discloses harmonic eddy current loss that simple structure, heat dispersion be good, reduce the motor, reliable and stable.
Description
Technical field
This utility model is related to a kind of rotor, and in particular to a kind of brushless electric motor rotor.
Background technology
The rotor of traditional type brushless electric machine, its surface patch magnet steel, protects rotor, it is ensured that magnetic using steel bushing or without latitude fiber
The centrifugal force that steel is produced during rotation gets rid of magnet steel.Shortcoming is exactly that stainless steel sleeve can produce harmonic wave eddy-current loss,
And do not allow easy heat radiation without latitude fiber band.
The content of the invention
For the deficiencies in the prior art part, this utility model provides a kind of simple structure, perfect heat-dissipating, reduces motor
Harmonic wave eddy-current loss, reliable and stable brushless electric motor rotor.
To reach above-mentioned purpose, the technical scheme that this utility model is adopted for：
A kind of brushless electric motor rotor, including the rotating shaft of six magnet steel, rotor core and rotor core coaxial cooperations, edge turns
The peripheral surface of sub- iron core is evenly equipped with six magnet steel grooves, and six magnet steel are embedded in respectively in six magnet steel grooves, in two adjacent magnetic
The teeth portion of projection is provided between steel tank, on the top of teeth portion groove is provided with, interference fit has pin in groove.
The material of pin is de- magnetic stainless steel material.
The beneficial effects of the utility model are：By being embedded in the groove of rotor core using pin interference, and pin
The groove size of rotor core is slightly larger in dimension than, the effect that magnet steel reaches fixed magnet steel is blocked by extruding force.Iron core
Teeth portion open up groove also have optimization magnetic circuit trend effect, make motor breath magnetic it is close be more nearly sine wave, so as to reduce
The harmonic wave eddy-current loss of motor, reduces the vibrating noise of motor, and the utility model simple structure, and thermal diffusivity is good.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of rotor core.
Wherein：1, magnet steel；2, rotor core；2-1, magnet steel groove；2-2, teeth portion；2-3, groove；3, pin；4, rotating shaft.
Specific embodiment
This utility model is further described below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, a kind of brushless electric motor rotor, including six magnet steel 1, rotor core 2 and rotor cores 2 are same
The rotating shaft 4 that axle coordinates,
Six magnet steel groove 2-1 are evenly equipped with along the peripheral surface of rotor core 2, six magnet steel 1 are embedded in respectively six magnet steel grooves
In 2-1, teeth portion 2-2 of projection is provided between two adjacent magnet steel groove 2-1, on the top of teeth portion 2-2 groove 2-3 is provided with,
Interference fit has pin 3 in groove 2-3.
The material of pin 3 is de- magnetic stainless steel material.
The beneficial effects of the utility model are：By being embedded in the groove 2-3 of rotor core 2 using the interference of pin 3, and
The diameter dimension of pin 3 blocks magnet steel 1 and reaches fixed magnet steel slightly larger than the size of the groove 2-3 of rotor core 2 by extruding force
1 effect.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement expected without creative work all should be covered within protection domain of the present utility model.
Therefore, the protection domain that protection domain of the present utility model should be limited by claims is defined.
