Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An axial magnetic field double-rotor permanent magnet vernier motor is shown in figures 1-3 and comprises a single stator 1 and two rotors 2, wherein the rotors 2 are positioned on two axial sides of the stator 1, the intervals are equal, one sides of grooves of the two rotors are opposite, the stator and rotor disks are coaxially connected to form two layers of air gaps, and permanent magnets opposite to the rotors on the two sides completely correspond in the circumferential direction without dislocation.
The stator 1 comprises a sectional stator iron core 1-1, a stator permanent magnet 1-2, an armature winding 1-3 and a stator support, the rotor 2 comprises a rotor iron core 2-1, a rotor permanent magnet 2-2, a rotor support frame, a bearing and a rotating shaft, and the rotor 2 is in a circular ring shape and is connected with the rotating shaft through the rotor support frame and the bearing. One axial side of the rotor core 2-1 is uniformly provided with pr second grooves along the circumferential direction, fan-shaped rotor permanent magnets 2-2 are placed in the second grooves, and the magnetizing directions of the rotor permanent magnets 2-2 are axial and the same.
The stator core 1-1 comprises a plurality of stator modules which are identical in structure and distributed in a circumferential array, and the stator modules are fixed by a bracket made of non-magnetic materials and rigidly connected with a machine shell to form a whole. The number of the stator modules is z, the stator modules comprise 1 armature tooth 1-1-1 and 2t modulation teeth 1-1-2, the modulation teeth 1-1-2 positioned on two sides are symmetrically arranged, and the armature windings 1-3 are directly wound on the armature tooth parts, so that the coil planes are perpendicular to the axial direction.
In the stator iron core 1-1, t modulation teeth 1-1-2 are connected to two axial sides of each armature tooth 1-1-1, t-1 first grooves are formed in each side, stator permanent magnets 1-2 are placed in the first grooves, and the stator permanent magnets 1-2 are Halbach array permanent magnets. The space formed between the armature teeth 1-1-1 of the adjacent stator modules is equivalent to z stator slots of the motor, the stator slots are parallel slots, armature windings 1-3 are arranged in the stator slots, the armature windings 1-3 are fractional slot concentrated windings and can be double-layer windings or single-layer windings, and the coil plane is vertical to the axial direction. The stator permanent magnet 1-2 is composed of three permanent magnets, the magnetizing direction of the middle permanent magnet is axial, and the magnetizing directions of the permanent magnets on the two sides are circumferential.
The stator permanent magnet 1-2 and the rotor permanent magnet 2-2 are both made of hard magnetic materials with high remanence, and the stator iron core and the rotor iron core are made of high magnetic conductive materials.
According to the magnetic field modulation principle, the number z of the stator modules, the modulation tooth number t, the second groove number pr and the number ps of the armature winding pole pairs satisfy the following relation: zxt ═ pr + ps. The present invention will be described with reference to examples, wherein z is 12, t is 3, pr is 35, and ps is 1. By changing the numerical values of z, t, pr and ps, the numerical values are mapped to different structures to generate different rotating speeds and torque outputs so as to adapt to different application occasions.
The magnetic field of the rotor permanent magnet enters the stator core 1-1 from the N pole through an air gap, passes through another layer of air gap after passing through the modulation teeth on one side, the armature teeth and the modulation teeth on the other side, and enters the rotor 2 on the other side, so that a closed loop is formed. Most of the traditional dual-rotor axial magnetic field motors adopt a stator yoke structure, and a main magnetic circuit needs to be closed through a stator yoke. The stator yoke-free structure adopted by the invention can reduce the stator mass and the stator core loss.
When the motor-driven generator operates, three-phase symmetrical current is introduced into the stator winding to generate a circular rotating magnetic field with the rotating speed of omega s, and the rotating magnetic field is changed into a rotating magnetic field with the rotating speed of omega r after the modulation effect of the modulation teeth, and the relation is satisfied: ω s/ω r ═ pr/ps. The sign indicates that the two rotating magnetic fields are opposite in direction. Typically, pr is greater than ps, and therefore ω r is less than ω s, i.e. the rotational speed of the rotor is slowed by a factor of pr/ps. When the frequency of the input current is adjusted, the output speed is adjusted. In the same way, when the prime motor is dragged to enter the power generation operation, the energy transfer direction is reversed, and the rotation speed ratio of the stator and rotor magnetic fields is the same as that of the electric operation.
The arrangement mode of the permanent magnets of the rotor is also an alternating pole arrangement, the traditional N-S-N-S mode is changed into an N-iron core-N-iron core mode, the proportion of the permanent magnets in each pole can be regarded as the pole arc coefficient of the permanent magnets, and the sine degree of the air gap magnetic field waveform can be improved by adjusting the pole arc coefficient, so that the magnetic flux linkage and the no-load back electromotive force waveform are improved. The alternating pole arrangement can reduce the use amount of the permanent magnet and ensure that the output torque is not changed greatly, so that the utilization rate of the permanent magnet is improved. The adoption of the stator permanent magnet 1-2 improves the magnetic field intensity of the main flux, and compared with a structure without the stator permanent magnet, the output torque is improved. In addition, in the stator permanent magnets 1-2, the proportion of the middle permanent magnet to the three permanent magnets affects the output torque of the motor, and the proportion is adjusted to enable the middle permanent magnet to be as large as possible, the magnetic leakage of the permanent magnet to be as small as possible, and the output torque is maximum at the moment.
Compared with the traditional radial magnetic field magnetic circuit structure, the radial magnetic field magnetic circuit structure has the advantages that the power density is increased, the size of the motor is reduced, the axial length is short, and the radial magnetic field magnetic circuit structure is suitable for occasions with compact axial space; the stator adopts the segmentation modular structure, does not have stator yoke portion, and the stator core loss reduces, and motor efficiency promotes. Compared with a single-rotor single-stator structure, the double-side rotor structure has no unilateral magnetic tension, and ensures the mechanical reliability; halbach permanent magnet is added to the stator side, reduces the stator magnetic leakage, increases torque density for the motor is applicable to the high-torque direct drive occasion such as elevator traction, electric automobile wheel hub drive, wind power generation etc..
The invention designs an axial magnetic field vernier motor, which enables an armature magnetic field to generate a magnetic field modulation phenomenon in a mode of adding modulation teeth on stator armature teeth, and the magnetic field modulation phenomenon interacts with a magnetic field generated by a rotor permanent magnet to generate stable torque output. The rotor structure of the modulation ring of the traditional axial magnetic field vernier motor is avoided, the complexity of the system is reduced, and the volume of the motor is reduced; the segmented modular rotor is adopted, so that the loss of a stator core is reduced, the efficiency of the motor is improved, and the quality of the motor is reduced; and a Halbach array permanent magnet is added into the stator, so that the air gap flux density is increased, and the torque density of the system is improved.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
