Summary of the invention
In view of above-mentioned new-energy automobile permagnetic synchronous motor easily demagnetize, the deficiency such as overload magnification is little, the life-span is short, the present invention's
Purpose is to provide a kind of ultra high efficiency New energy automobile motor, is used for solving the problems referred to above of the prior art.
For achieving the above object and other relevant purposes, the present invention provides a kind of ultra high efficiency New energy automobile motor, including:
Having 44 teeth groove, the rotor of 4 rotor poles, described teeth groove is tilt along rotor outer circle bus；The yoke of described rotor
Portion is provided with some air vents, and described air vent divides inside and outside two-layer to arrange, and is respectively distributed to the geometric center of rotor as common circle
The heart and on different two circles of radius；
Having the stator of 36 teeth groove, the yoke portion of described stator is provided with some air vents.
Preferably, the slot slope of described rotor is 8mm to 9.6mm.
It is further preferred that the slot slope of described rotor is 8.8mm.
Preferably, the internal layer air vent of described rotor is interspersed with the outer layer air vent of rotor.
Preferably, the air vent of described rotor substantially kidney-shaped, its cross-sectional profiles line by Inner arc, external arc with described
The semi arch of inside and outside circular arc both sides is formed by connecting.
Preferably, the two ends of described rotor are provided with cast aluminium end ring, and described cast aluminium end ring arranges balance columns and fan blade.
Preferably, the teeth groove of described rotor is for tiltedly takeing on flat-bottom slot.
Preferably, the teeth groove of described stator is peariform slot.
Preferably, the air vent of described stator is triangle.
As it has been described above, the ultra high efficiency New energy automobile motor of the present invention, have the advantages that
(1) cogging torque in permagnetic synchronous motor can cause the velocity perturbation of motor, vibration and noise, at light load and low speed
Time especially heavy load can be fairly obvious when starting, stall when serious meeting causes electric motor starting.Ultra high efficiency for the present invention
For New energy automobile motor, owing to motor of the present invention is provided without magnet steel, so there is not cogging torque in motor, so that motor
Operation more steady, torque ripple is less.Meanwhile, motor uses rotor chute structure to reduce the operating noise of motor.
(2) the circle air vent that ultra high efficiency New energy automobile motor of the present invention is arranged in stator yoke can greatly speed up motor
Heat radiation, can effectively extend the service life of motor.The rotor yoke of motor also has two-layer air vent, on the one hand, enhance
The heat-sinking capability of motor, on the other hand, reduces the rotary inertia of motor, makes the acceleration and deceleration of motor react faster.
(3) in the present invention, the balance columns on cast aluminium end ring is used for regulating the dynamic balancing use of motor, and fan blade runs at motor
Time accelerate motor internal circulation cooling；
(4) reselect electric machine rotor slot fit, redesign electric machine rotor grooved, make electric efficiency and power factor (PF) all
It is improved.
(5) casting aluminum rotor uses aluminium alloy, reduces the resistivity of casting aluminium material, makes the resistance of rotor end ring and sliver more
Little, reduce the copper loss of motor.
Make after model machine with permagnetic synchronous motor performance comparison on market (as a example by 3KW motor)
