The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 2-4, an embodiment of the present invention provides a surface-mount motor rotor, in which a magnetic steel 2 of the surface-mount motor rotor has an outer side surface facing a stator 1, and both sides of the outer side surface have a trimming structure symmetrically disposed along a central line thereof.
The embodiment of the utility model provides a surface-mounted electric motor rotor has the side cut structure that sets up along its central line symmetry through the both sides at the lateral surface, can change the air gap length of motor along each position of the interior round surface of stator 1, and then improves air gap magnetic field for air gap magnetism is close and counter electromotive force waveform sine degree improves, has reduced the harmonic and has accounted for the ratio, and then has reduced torque ripple, has effectively reduced motor vibration noise.
It will be appreciated that the trim structure is an edge structure from which a portion of an existing solid structure has been cut. The surface-mounted motor rotor comprises a rotating shaft 4, a rotor iron core 3 and magnetic steel 2.
As shown in fig. 2, 3 and 4, the trimming structure of the outer side surface is an eccentric arc surface arranged at two sides of a middle arc surface of the outer side surface, and the eccentric arc surface is bent towards the inner side of the surface-mounted motor rotor; the eccentric cambered surface and the middle cambered surface are in smooth transition. In the present embodiment, the outer surface of the magnetic steel 2 of the rotor of the surface-mount motor is cut off, and the structure of the stator 1 may be the same as that of the stator 1 in the prior art. The eccentric arc surface is an arc surface structure with a circle center not coincident with the circle center of the surface-mounted motor rotor.
Of course, the edge cutting structure of the outer side face can be arranged in other structures, such as a plane and the like.
Preferably, the closer the eccentric arc surface is to the magnetic pole boundary line of the magnetic steel 2, the greater the radian of the eccentric arc surface. The connecting point of the eccentric arc surface and the middle arc surface is a W point, the eccentric arc changes along a curve function from the W point to the direction of the boundary line of the magnetic pole, and the eccentric arc of the magnetic steel 2 extends along the circumferential direction. Through the arrangement, the air gap permeance of the magnetic circuit is more uniform.
In the embodiment, the radian of the eccentric cambered surface is A/2, and the angle occupied by a single magnetic pole of the surface-mounted motor rotor is F. Simulation research shows that the ratio of the radian of the eccentric arc surface to the radian of the middle arc surface has great influence on the air gap flux density harmonic ratio. The eccentric cambered surface is arranged on the magnetic steel 2, so that the magnetic pole shape of the magnetic steel 2 is changed, the magnetic pole of the magnetic steel 2 is in a salient pole shape, and the air gap length of different positions on the surface of the rotor is changed. When A/F is larger than or equal to 0.25, the length of the air gaps on the two sides of the magnetic pole is increased, the air gap permeance on the two sides of the magnetic pole is reduced, the air gap magnetic density on the two sides of the magnetic pole is further reduced, the mutability of the change of the permeance is reduced, the change of the permeance is more uniform, the waveform of the air gap magnetic density is close to a sine wave, the air gap magnetic density and the counter potential harmonic ratio are reduced, and the vibration noise is further effectively reduced. However, when a/F is greater than 0.7, the radian of the eccentric arc surfaces on the two sides of the magnetic pole is too large, so that the air gap length of most positions on the surface of the rotor is increased, the air gap magnetic conductance of most positions on the surface of the rotor is reduced, the air gap magnetic flux density of the surface of the rotor is reduced, the air gap magnetic flux density waveform is not improved, the waveform distortion rate is still high, the vibration noise of the motor is still large, meanwhile, the air gap length is too large, the magnetic flux leakage is increased, the flux linkage of the motor is reduced, the torque of the motor is reduced, and the. Therefore, preferably, 0.7. gtoreq.A/F. gtoreq.0.25.
As shown in fig. 4 and 8, the number of pairs of magnetic poles of the motor is P, and the radian of the eccentric arc surface is a/2; an included angle between a connecting line of any eccentric point and a connecting line of the eccentric connecting point is set to be theta 3, the connecting line of any eccentric point is a connecting line of any point on the eccentric arc surface and the center of the surface-mounted motor rotor, the connecting line of the eccentric connecting point is a connecting line of the W connecting point and the center of the surface-mounted motor rotor, and the W connecting point is a connecting point of the middle arc surface and the eccentric arc surface, so that A/2 is more than theta 3 and more than 0 degrees, and theta 3 is gradually increased in the process that the eccentric arc surface changes along the curve until the W point changes to the edge lines on the two sides. Wherein, the distance between any point on the eccentric cambered surface and the circle center of the surface-mounted motor rotor is eccentricThe diameter R6, i.e., the eccentric diameter R6, becomes gradually smaller as it changes from point W along the curve. The eccentric diameter R6 and the radius R5 of the middle cambered surface satisfy the following relation:whereinThrough the setting, the air gap length of the stator 1 and the rotor corresponding to the trimming position (eccentric arc surface) of the magnetic steel 2 is increased, and the air gap length is reduced, so that the air gap magnetic conductance of a magnetic circuit is changed more uniformly, the sine degree of the air gap magnetic density waveform on the surface of the rotor is improved, the harmonic ratio is reduced, the torque pulsation is reduced, the vibration noise and the harmonic loss of the motor are reduced, and the motor efficiency is improved.
The angle of the gap between two adjacent magnetic steels 2 is C, and the angle occupied by a single magnetic pole of the surface-mounted motor rotor is F. Research shows that when the C/F is larger than or equal to 0.15, a fastener is conveniently arranged between the magnetic steel 2 and the magnetic steel 2, and the mechanical strength of the integral structure of the rotor is enhanced; however, when the ratio of C/F is more than or equal to 0.2, the pole arc coefficient is reduced, and the utilization rate of the magnetic steel 2 is reduced, so that the output torque of the motor is reduced. Therefore, preferably, 0.2. gtoreq.C/F. gtoreq.0.15.
It can be understood that, at the position where neither the stator 1 nor the magnetic steel 2 is trimmed, the air gap is the smallest, and the air gap length is D, and moving clockwise or counterclockwise along the surface of the magnetic steel 2 of the rotor from the position where the air gap is the smallest, the air gap length gradually increases.
As shown in fig. 5, 6 and 7, the embodiment of the present invention further provides a stator, wherein the tooth shoe of the stator has an inner side surface facing the surface-mounted electric motor rotor, and both sides of the inner side surface have a trimming structure symmetrically disposed along the center line thereof.
The embodiment of the utility model provides a stator has the side cut structure that sets up along its central line symmetry through the both sides at the medial surface, can change the air gap length of the motor along each position of circle surface in stator 1, and then improves air gap magnetic field for air gap magnetic density and counter electromotive force waveform sine degree improve, have reduced the harmonic and have accounted for than, and then have reduced torque pulsation, have effectively reduced motor vibration noise.
It will be appreciated that the trim structure is an edge structure from which a portion of an existing solid structure has been cut.
Preferably, the cutting edge structure of the inner side surface is a curved section disposed at both sides of the middle surface of the inner side surface, and the curved section is curved toward the inner side of the stator 1. In the present embodiment, the inner surface of the tooth shoe of the stator 1 is cut away, and the structure of the rotor may be the same as that of the prior art.
Of course, the edge cutting structure of the inner side face can be arranged in other structures, such as a plane and the like.
Wherein, the radian of the section of the curve is G/2, and the angle occupied by a single tooth shoe of the stator 1 is H. As shown in fig. 5, the connection point of the middle plane and the curved section is a point T, and the cutting position (curved section) of the tooth shoe of the stator 1 is close to the part of the air gap between the stator and the rotor. Simulation research shows that the ratio of radian occupied by a curve tangent plane (the cutting position of the tooth shoe of the stator 1) to the angle occupied by a single tooth shoe is H, so that the air gap flux density harmonic has large influence. When G/H is larger than or equal to 0.4, the radian of the curve section is larger, so that the transition of the air gap length on the inner surface of the motor stator 1 is more uniform, the uniformity of the magnetic conductance of the air gap of the magnetic circuit is improved, the air gap flux density and counter potential waveform are improved, the harmonic ratio is reduced, and the vibration noise of the motor is reduced. However, when G/H is larger than 0.7, the arc angle of the curve section is too large, and the magnetic flux is excessively concentrated at the center line of the tooth shoe of the stator 1, so that the air gap magnetic density at the position is too high, the air gap magnetic density waveform is seriously distorted, the harmonic ratio is increased, and the vibration noise of the motor is increased. Therefore, preferably, 0.7. gtoreq.G/H. gtoreq.0.4.
Preferably, the number of the slots on the stator 1 is Q, the radian of the curve section is G/2, the included angle between the connecting line of any point of the curve and the connecting line of the connecting point of the curve is set to be theta 2, and the connecting line of any point of the curve is the connecting line between any point of the curve section and the circle center of the stator (1); the connecting line of the curve connecting points is the connecting line of the T connecting point and the circle center of the stator 1, and the T connecting pointIs the junction of the median plane and the curved section. G/2 > theta 2 > 0o, wherein the stator 1 is concentric with the rotor, theta 2 is gradually increased in the process that the cutting edge of the stator 1 changes along a curve, and the section of the curve changes along the curve from a point T until the section of the curve is overlapped with the edge line of the tooth shoe of the stator 1. The distance between any point on the section of the curve and the center of the stator 1 is the cutting edge diameter R4 of the stator 1. That is, the cutting edge diameter R4 of the stator 1 becomes gradually larger in the process of changing from the point T along the curve, and the cutting edge diameter R4 of the stator 1 and the inner circle radius (i.e., the radius of the middle surface) R3 of the stator 1 satisfy the following relationship:whereinThe change of the air gap magnetic conductance of the motor is more uniform, the sine degree of the air gap magnetic flux density waveform is improved, the harmonic wave occupation ratio and the torque ripple are reduced, the vibration noise and the harmonic wave loss of the motor are also reduced, and the motor efficiency is improved.
Wherein Q is more than or equal to 4. In this embodiment, Q is 12.
