Long-pending utilization rate.
When a angle is less than normal, square magnetic steel 3 is intersected with the direction of magnetization of arc magnet steel 4 intersection, its conjunction
Become magnetomotive force size to be less than two magnetomotive force sums, that is, weaken the magnetomotive force that respective magnet steel produces.
When a angle is bigger than normal, (Fig. 3), so that thickness h pm at arc magnet steel 4 center is less than normal, leads to arc
The magnetomotive force of magnet steel 4 reduces.When a angle is at 70～110 degree, can make full use of square magnetic steel 3 with
The magnetomotive force of arc magnet steel 4, improves the utilization rate of magnet steel volume.
In specific embodiment, two sections of square grooves 1 in each permanent magnet trough are set to off in rotor
Article one, diameter symmetry arrangement, and the two neighboring square groove 1 in two adjacent permanent magnets groove is arranged in parallel.
Two sections of square grooves 1 in permanent magnet trough are arranged with regard to the diameter symmetry of rotor, can make permanent magnet trough circumferentially
Regular arrangement, identical with the magnetic that ensures rotor various pieces, prevent the phenomenon of magnetic mutation, protect
Demonstrate,prove the stability of this rotor.Make adjacent in adjacent permanent magnet trough two square by be arrangeding in parallel
There is no angle between groove 1, that is, ensure that the end of square groove 1 is parallel with the outer ring tangent line of rotor, it is possible to increase
The size of square groove 1, and then the size of permanent magnet can be increased, improve the energy of magneto output torque
Power.
In one embodiment, arcuate groove 2 is all connected with two sections of square grooves 1, to increase further
The volume that magnet steel takies, increases motor output torque.
In practice also can according to different need for arcuate groove 2 to be divided into three parts with two sections of square grooves 1 set
Put, so setting can strengthen the intensity of rotor structure, further, can be in arcuate groove 2 and square groove 1
Between magnetic conduction bridge 5 is set, due to there is magnetic conduction bridge 5, when there is demagnetized field, demagnetization magnetomotive
A part is shunted through magnetic conduction bridge 5, and the demagnetization magnetic potential through magnet steel accordingly reduces, and then improves
The anti-demagnetization capability of motor.
In preferred embodiment, the mode of magnetizing of above-mentioned square magnetic steel is along perpendicular to square magnetic steel 3
Magnetize in the direction on long side, and the mode of magnetizing of arc magnet steel 4 is the radial magnetizing of arcuately magnet steel 4.Right
In the arc magnet steel 4 of radial magnetizing, the intersection point of its direction of magnetization substantially in the home position of arc magnet steel 4,
When arcuate groove 2 is arc groove, the extended line at arc magnet steel 4 two ends meets at the center of circle of arc magnet steel 4.
By the matched combined of parallel magnetization and radial magnetizing, the utilization rate of magnet steel can be improved.
On the basis of technique scheme, the axis of symmetry of arcuate groove 2 and this permanent magnetism in the rotor of the application
The symmetrical overlapping of axles of two sections of square grooves 1 of body, that is, U-type groove structure is a diameter symmetry with regard to rotor,
By permanent magnet trough is set to the uniformity that symmetrical mode can improve permanent magnet distribution.
In further embodiment, the inner arc of arcuate groove 2 and outer arc are set to concentric circular arc.Setting
The processing to arcuate groove 2 and arc magnet steel 4 can be easy to for circular arc.
Additionally, also the inner arc of arcuate groove 2 can be set to circular arc, and outer arc is arranged in parallel to inner arc
The straight line of tangent line.Specifically, the straightway of outer arc and the straight line segment of square magnetic steel 3 are connected by arc transition
Connect.The arcuate groove 2 of this structure in guarantee rotor structure intensity, that is, can ensure magnet steel groove and rotor
On the premise of minimum range between internal diameter is constant, increase the area of magnet steel groove further, therefore can embed
The magnet steel of more volumes, and then improve motor torque fan-out capability.
On the basis of technique scheme, another inventive point of the application is will be corresponding for square groove 1
Rotor is set to straightway at outer ring.Specifically, this straightway is the string of former round rotor, i.e. this rotor
Outer ring profile there is straightway, so setting can increase the rotor portion of permanent magnet end correspondence position with
Air gap separation between stator, thus dropping low magnetic density, reduces iron loss phenomenon.
In specific embodiment, rotor outer ring is set to the structure of straightway and the alternate arrangement of arc section.
Need arc section is improved also dependent on different in practice, and all in protection domain.
In one embodiment, the end of the straightway of rotor and square groove 1 is be arranged in parallel, this is straight
Line segment and square groove 1 are positioned opposite.Further, by the two neighboring side of two adjacent permanent magnets groove
Shape groove 1 is set to off being arranged symmetrically in the perpendicular bisector of the straightway of outer ring.Can entirely by above-mentioned setting
Rotor is set to off the structure in diameter symmetry so that the Distribution of Magnetic Field of rotor is symmetrical, to improve motor work
The stability made.
In order to reduce the noise of motor, in the application, the length of the straightway of rotor outer ring is set greater than
The distance between relative outer side edges of two square grooves 1 of this straightway, two square grooves 1 herein are
The two neighboring square groove 1 of two adjacent permanent magnet trough, outer side edges are that this two square grooves 1 are relatively remote
On one side.So setting can reduce the air gap separation between straightway end and stator, thus weakening permanent magnetism
The air gap flux density of body end portion correspondence position, reduces corresponding electromagnetic force amplitude, and then reduces the vibration of motor
Noise.Line correspondence section can be illustrated by other parameter than also with the length of square groove 1, for example
The radian of the vertex correspondence of the outer side edges of be arranged in parallel two square grooves 1 is set to θ c, and by straight line
Section corresponding maximum radian is set to θ r, and sets θ r >=θ c.
