Description
技术领域technical field
本发明涉及电机技术领域，尤其涉及一种双转子永磁电机以及带有该双转子永磁电机的洗衣机。The invention relates to the technical field of motors, in particular to a double-rotor permanent magnet motor and a washing machine with the double-rotor permanent magnet motor.
背景技术Background technique
洗衣机是人们日常生活中必不可少的家用电器，其耗电量，振动噪音大小是衡量洗衣机品质的一个重要标准。目前国内常用的单筒全自动洗衣机基本分为波轮洗衣机和滚筒洗衣机两种，其基本工作模式主要分为洗涤和甩干两种。通常洗涤工况下，波轮（波轮洗衣机）或滚筒（滚筒洗衣机）转速较低，为100～200r/min，而脱水工况下，脱水筒或滚筒的转速较高，通常在1000r/min。传统的洗衣机驱动多采用一台电机，通过皮带轮、减速箱、和离合器达到洗涤时低速大扭矩，脱水时高速旋转的目的。然而这种方式在达到洗涤和脱水的效果的同时也会带来噪声大、机身震动、浪费能源及因磨损而容易出现故障等缺点。Washing machine is an indispensable household appliance in people's daily life. Its power consumption and vibration noise are important criteria to measure the quality of washing machine. At present, the commonly used single-cylinder fully automatic washing machines in China are basically divided into two types: top-loading washing machines and drum washing machines, and their basic working modes are mainly divided into two types: washing and drying. Usually, under washing conditions, the speed of the pulsator (wave wheel washing machine) or drum (drum washing machine) is low, 100-200r/min, while under dehydration conditions, the speed of the dehydration drum or drum is relatively high, usually 1000r/min . The traditional washing machine is driven by a single motor, which achieves the purpose of low-speed high-torque during washing and high-speed rotation during dehydration through pulleys, reduction boxes, and clutches. However, when this method achieves the effect of washing and dehydration, it will also bring disadvantages such as loud noise, vibration of the fuselage, waste of energy, and failures due to wear and tear.
此外，目前市场上出现的采用普通无刷直流电机直接驱动的洗衣机省去了皮带轮和传输带，电机可直接工作在宽转速功率范围，大大降低了噪声，提高了传动效率。但由于电机特性的限制，虽然普通的无刷直流电机可以实现满足洗衣机工况的较大转速范围内的功率输出，但是，电机同时运行在低速大扭矩和高速两种工况下，很难保证每种工况下，电机都处于最佳的工作状态，因此，无刷直流电机在洗衣机应用领域，相对其在其它应用领域而言，电机在全工况范围内，整体性能较低。In addition, the washing machines that are directly driven by ordinary brushless DC motors on the market do not need pulleys and transmission belts, and the motors can directly work in a wide range of speed and power, which greatly reduces noise and improves transmission efficiency. However, due to the limitation of motor characteristics, although ordinary brushless DC motors can achieve power output within a large speed range that meets the working conditions of washing machines, it is difficult to ensure that the motor operates under low-speed, high-torque and high-speed conditions at the same time. Under each working condition, the motor is in the best working condition. Therefore, the brushless DC motor in the washing machine application field, compared with other application fields, the overall performance of the motor is lower in the full range of working conditions.
因此，如何使电机在最佳工作状态下即能输出低速大扭矩，又能输出高速驱动成为研究的重点。Therefore, how to make the motor output both low-speed high-torque and high-speed drive under the optimal working condition has become the focus of research.
双转子永磁电机具有体积小、重量轻等优点，例如申请号为200410075764.3的中国发明专利申请公开一种双转子永磁电机，双转子共用一个定子，定子由定子铁心和定子绕组构成，但该技术中内外两个转子都是通过定子产生的磁场来驱动，内外转子转速受限，无法同时实现洗衣机在洗涤和脱水两种工况下采用不同转速的功能。The double-rotor permanent magnet motor has the advantages of small size and light weight. For example, the Chinese invention patent application number 200410075764.3 discloses a double-rotor permanent magnet motor. The two rotors share a stator. The stator is composed of a stator core and a stator winding. In the technology, the inner and outer rotors are both driven by the magnetic field generated by the stator, and the speed of the inner and outer rotors is limited, so it is impossible to realize the function of the washing machine using different speeds under the two working conditions of washing and dehydration at the same time.
发明内容Contents of the invention
本发明基于磁场调制原理，提供一种同时实现高速小扭矩和低速大扭矩的双转子永磁电机及使用该双转子永磁电机的洗衣机，该双转子永磁电机具备双功率输出端口，外转子和内转子可按一定比例关系旋转，通过电机的合理设计以满足洗衣机洗涤和脱水的不同工况需求。Based on the principle of magnetic field modulation, the present invention provides a dual-rotor permanent magnet motor capable of simultaneously realizing high-speed small torque and low-speed high torque and a washing machine using the dual-rotor permanent magnet motor. The dual-rotor permanent magnet motor has dual power output ports, and the outer rotor And the inner rotor can rotate according to a certain ratio, and the rational design of the motor can meet the needs of different working conditions of washing and dehydration of the washing machine.
一种双转子永磁电机，包括从内向外依次布置的内转子、定子和外转子，所述内转子和外转子均为永磁体转子，所述定子包括磁调制环以及绕置在该磁调制环上的定子绕组。A dual-rotor permanent magnet motor, comprising an inner rotor, a stator and an outer rotor arranged sequentially from the inside to the outside, the inner rotor and the outer rotor are both permanent magnet rotors, the stator includes a magnetic modulation ring and is wound on the magnetic modulation The stator winding on the ring.
本发明双转子永磁电机中改变了现有双转子永磁电机的定子结构，采用了可传导磁场的磁调制环，工作时定子绕组通过产生磁场驱动内转子，内转子转动后也会产生变化的磁场，该变化的磁场通过磁调制环传递并施加至外转子，使外转子开始转动，这样可以避免内外转子的转速同时受定子影响，通过调节内外转子的极对数关系，可以得到适宜的外转子转速。In the dual-rotor permanent magnet motor of the present invention, the stator structure of the existing dual-rotor permanent magnet motor is changed, and a magnetic modulation ring capable of conducting a magnetic field is adopted. During operation, the stator winding drives the inner rotor by generating a magnetic field, and the inner rotor will also change after it rotates. The changing magnetic field is transmitted through the magnetic modulation ring and applied to the outer rotor, so that the outer rotor starts to rotate, which can prevent the speed of the inner and outer rotors from being affected by the stator at the same time. By adjusting the pole logarithm relationship of the inner and outer rotors, a suitable The speed of the outer rotor.
本发明双转子永磁电机具备了磁场调制式磁性齿轮的特点，比如，内外转子以一定的传动比转动，输送较高的转矩密度等。也就是说，实现了电机在工作时既能输出低速大扭矩又能输出高速小扭矩的技术要求。The double-rotor permanent magnet motor of the present invention has the characteristics of magnetic field modulation type magnetic gears, for example, the inner and outer rotors rotate with a certain transmission ratio, and deliver higher torque density and the like. That is to say, the technical requirement that the motor can output both low-speed high-torque and high-speed low-torque when working is realized.
所述磁调制环带有沿周向均匀分布的若干调磁齿，相邻调磁齿之间为齿槽，所述定子绕组布置在对应的齿槽中。The magnetic modulation ring has several magnetic modulation teeth evenly distributed along the circumferential direction, and there are tooth slots between adjacent magnetic modulation teeth, and the stator windings are arranged in the corresponding tooth slots.
就磁调制环本身的的材质和结构而言可以采用现有技术，磁调制环内缘具有较薄的轭部，也仅仅是为了连接各个调磁齿。As far as the material and structure of the magnetic modulation ring itself is concerned, the existing technology can be used. The inner edge of the magnetic modulation ring has a thinner yoke, which is only for connecting each magnetic modulation tooth.
所述内转子的极对数与所述定子绕组的极对数相同；所述外转子的极对数与内转子的极对数之和等于调磁齿的齿数。The number of pole pairs of the inner rotor is the same as that of the stator winding; the sum of the number of pole pairs of the outer rotor and the number of pole pairs of the inner rotor is equal to the number of magnetic teeth.
内转子的极数与所述定子绕组的极数相同可以保证定子绕组通电后产生的磁场与转子匹配，能够对应的驱动内转子，而外转子的极对数与内转子的极对数之和等于调磁齿的齿数可以使内转子恰好相应的驱动外转子。The number of poles of the inner rotor is the same as the number of poles of the stator winding, which can ensure that the magnetic field generated by the stator winding is matched with the rotor, and can drive the inner rotor accordingly, and the sum of the number of pole pairs of the outer rotor and the number of pole pairs of the inner rotor The number of teeth equal to the magnetic adjustment teeth can make the inner rotor drive the outer rotor just correspondingly.
另外由磁场调制式磁性齿轮的工作原理可知，当磁调制环极数（定子绕组的极对数）与内转子极对数相同时，外转子与内转子极对数之比等于其转速的反比。也就是说，内磁转子的极对数可以按内外转子转速的需要进行设计，即可实现内外转子按一定的传动比转动。In addition, it can be seen from the working principle of the magnetic field modulation magnetic gear that when the number of poles of the magnetic modulation ring (the number of pole pairs of the stator winding) is the same as the number of pole pairs of the inner rotor, the ratio of the number of pole pairs of the outer rotor to the inner rotor is equal to the inverse ratio of its speed . That is to say, the number of pole pairs of the inner magnetic rotor can be designed according to the speed requirements of the inner and outer rotors, so that the inner and outer rotors can rotate at a certain transmission ratio.
所述外转子的极对数不同于内转子的极对数。这样在定子绕组通电后产生的磁场无法有效的驱动外转子，一方面定子产生的磁场仅有很小一部分会影响至外转子，另一方面通过极对数的不同设置，进一步保证了外转子主要靠内转子驱动，而非靠定子驱动。The number of pole pairs of the outer rotor is different from the number of pole pairs of the inner rotor. In this way, the magnetic field generated after the stator winding is energized cannot effectively drive the outer rotor. On the one hand, only a small part of the magnetic field generated by the stator will affect the outer rotor; Driven by the inner rotor, not by the stator.
