Description

电机转子表贴磁钢间隔套Motor rotor surface mounted magnetic steel spacer

【技术领域】[Technical field]

本实用新型主要涉及一种电机转子表贴磁钢间隔套。The utility model mainly relates to a magnetic steel spacing sleeve attached to the surface of a motor rotor.

【背景技术】[Background technology]

在电机转子的结构中,磁钢被设计成间隔布置的形式,并且这些磁钢通常会被表贴在转子的表面或者槽内。这种设计旨在通过增加磁钢与转子的接触面积,从而提高磁力线的传递效率,增强电机的运转性能。同时,间隔布置的磁钢还可以减少磁钢间的相互干扰,提高电机的运行稳定性。In the structure of the motor rotor, the magnets are designed to be arranged in intervals, and these magnets are usually attached to the surface of the rotor or in the slots. This design aims to increase the contact area between the magnets and the rotor, thereby improving the transmission efficiency of the magnetic lines of force and enhancing the operating performance of the motor. At the same time, the interval arrangement of the magnets can also reduce the mutual interference between the magnets and improve the operating stability of the motor.

现在表贴永磁电机转子磁钢安装方法大部分都是在转子轴上划线或者铣磁钢槽这两种。划线的优点是成本低,缺点也明显生产效率低、容易贴歪、后期有脱落的风险使电机性能不稳定;铣磁钢槽虽然磁钢贴合一致性好,但铣槽成本高、加工慢。At present, most of the methods for installing the rotor magnets of surface-mounted permanent magnet motors are to mark or mill the magnet slots on the rotor shaft. The advantage of marking is low cost, but the disadvantages are also obvious: low production efficiency, easy to be crooked, and the risk of falling off in the later stage, which makes the motor performance unstable; although milling the magnet slots has good magnet fitting consistency, the cost of milling the slots is high and the processing is slow.

The following description of the embodiments with reference to the drawings is exemplary and intended to explain the utility model, and cannot be understood as limiting the utility model.

本实用新型提供的较佳实施例:如图1~图3所示,一种电机转子表贴磁钢间隔套,它包括转子铁芯1、间隔套2和磁钢3;间隔套2为一体式结构,间隔套2包括套环21和分隔筋条22,套环21分别设于分隔筋条22的两端;套环21与分隔筋条22两者的厚度一致,以保持间隔套2端面的平整,分隔筋条22环绕套环21间隔设置,且分隔筋条22之间的间距均匀。The preferred embodiment provided by the utility model: as shown in Figures 1 to 3, a motor rotor surface-mounted magnetic steel spacer sleeve, which includes a rotor core 1, a spacer sleeve 2 and a magnetic steel 3; the spacer sleeve 2 is an integrated structure, and the spacer sleeve 2 includes a ring 21 and a separation rib 22, and the ring 21 is respectively arranged at both ends of the separation rib 22; the thickness of the ring 21 and the separation rib 22 are consistent to maintain the flatness of the end face of the spacer sleeve 2, the separation ribs 22 are arranged around the ring 21 at intervals, and the spacing between the separation ribs 22 is uniform.

间隔套2连接于转子铁芯1,分隔筋条22、套环21、转子铁芯1的端面配合形成若干间隔均匀的接槽23,磁钢3的尺寸与接槽23的尺寸相对应,便于磁钢3紧凑安装在接槽23内;磁钢3连接于接槽23,以使相邻的磁钢3通过分隔筋条22限制相吸合。所述转子铁芯1套接有钢套4,且磁钢3接入于钢套4内。The spacing sleeve 2 is connected to the rotor core 1, and the separation ribs 22, the collar 21, and the end surface of the rotor core 1 cooperate to form a number of evenly spaced connection slots 23. The size of the magnetic steel 3 corresponds to the size of the connection slots 23, so that the magnetic steel 3 is compactly installed in the connection slots 23; the magnetic steel 3 is connected to the connection slots 23 so that adjacent magnetic steels 3 are attracted to each other through the separation ribs 22. The rotor core 1 is sleeved with a steel sleeve 4, and the magnetic steel 3 is connected to the steel sleeve 4.

所述转子铁芯1具有套接部11,套接部11的端面延伸出挡边12,间隔套2连接于套接部11使套环21抵接于挡边12,以限定安装在转子铁芯1的间隔套2位置。间隔套2与磁钢3贴接于套接部11的端面,磁钢3间隔套2的壁厚小于磁钢3厚度的三分之一,使磁钢3露出于间隔套2的端面,便于缠绕线圈。间隔套2的材质可采用不锈钢或者塑料。用于辅助贴合磁钢3,也能固定磁钢3,防止相邻磁钢3的相互吸合。间隔套2限定了各个磁钢3的位置,各个磁钢3与定子旋转磁场相互作用产生动力,并通过转子铁芯1进行动力传递,为防止磁钢3脱落,转子铁芯1套接有钢套4以将磁钢3抵接在接槽23。The rotor core 1 has a sleeve portion 11, and the end surface of the sleeve portion 11 extends out a rib 12. The spacer sleeve 2 is connected to the sleeve portion 11 so that the collar 21 abuts against the rib 12 to limit the position of the spacer sleeve 2 installed on the rotor core 1. The spacer sleeve 2 and the magnet 3 are attached to the end surface of the sleeve portion 11. The wall thickness of the spacer sleeve 2 of the magnet 3 is less than one-third of the thickness of the magnet 3, so that the magnet 3 is exposed at the end surface of the spacer sleeve 2, which is convenient for winding the coil. The material of the spacer sleeve 2 can be stainless steel or plastic. It is used to assist in attaching the magnet 3, and can also fix the magnet 3 to prevent adjacent magnets 3 from attracting each other. The spacer sleeve 2 defines the position of each magnet 3. Each magnet 3 interacts with the stator rotating magnetic field to generate power, and transmits power through the rotor core 1. In order to prevent the magnet 3 from falling off, the rotor core 1 is sleeved with a steel sleeve 4 to abut the magnet 3 against the connection slot 23.
