Description

一种固定磁隙的永磁调速器 一种固定磁隙的永磁调速器
技术领域
本发明涉及一种永磁调速器，具体涉及一种固定磁隙的永磁调速器。
背景技术
永磁调速器是通过永磁 体 的磁力耦合调速， 实现电动机和负载的软（磁）连接， 无任何影响电网的谐波产生 ， 可靠性高，并可在高温、低温、潮湿、肮脏、易燃易爆、电压不稳及雷电等各种恶劣环境下工作，大幅减轻机械振动，广泛应用于电力、钢铁、冶金、石化，造纸、市政、舰船、灌溉及采矿等行业 。而目前常用的永磁调速器均是通过调整气隙来实现转速调整的，磁路调节器的功率消耗大，且存在扭矩传递能力差、装配难度高、浪费大量稀土资源等缺点。
发明内容
针对上述问题，本发明提供一种可降低磁路调节器功率消耗、提高扭矩传递能力、降低装配难度、节约稀土资源的 一种固定磁隙的永磁调速器 。
目前的永磁调速器都是通过改变导体转子与永磁转子之间的气隙从而控制导体转子切割磁力线的多少，来实现转矩调整的，由于这种方式存在很多弊端，本发明基于电磁原理，从保持磁隙不变、改变磁力线的数量入手去设计新的永磁调速器，通过控制永磁转子对外展现的磁性大小，从而达到改变转矩的目的。
为解决上述问题，本发明采取的技术方案为： 一种固定磁隙的永磁调速器，包括与主动轴连接的外导体转子以及经从动轴同心穿过的第一内磁转子和第二内磁转子，所述的外导体转子沿其内圆周面周向分布有导体；所述的第一内磁转子和第二内磁转子分别沿各自的外圆周面周向均匀分布有至少一个第一内永磁体和第二内永磁体，第一内永磁体和第二内永磁体数量相同，每个内磁转子上的内永磁体磁极沿周向设置，且同一内磁转子上相邻两内永磁体相邻侧磁极相异，第一内永磁体和第二内永磁体的磁极端面侧分别设有第一铁轭和第二铁轭；在第一内磁转子上设有驱动第一内磁转子相对第二内磁转子转动的磁路调节器，用于调节两内磁转子上内永磁体同名磁极的位置关系。
所述的磁路调节器用于调节第一永磁体和第二永磁体同名磁极的位置关系，进而改变对外显示的磁性强度。调速器原理：导体转子转动时与内部永磁转子产生相对运动， 永磁场在导体转子上产生涡流，同时涡流又产生感应磁场与永磁场相互作用，最终带动 永 磁转子沿与导体转子相同的方向转动，从而带动连接在永磁转子上的从动轴转动并输出动力 。而输出的动力与 永磁转子的磁场强度（磁力线强度）成正比，永磁转子的磁场强度由磁路调节器控制 。故本发明中可以通过 磁路调节器控制第二内磁转子的旋转来改变第一、第二铁轭对外显示的磁性， 从而引起 外导体转子 与从动轴产生转速的差异变化最终实现调速的目的。 具体调节过程： 通过磁路调节器 旋转可 第一内磁转子 ，当 第二内永磁体与第一内永磁体的同名磁极处于相对应的位置时，第一铁轭、第二铁轭均被 磁化成相对应极性的强磁体 ，对外显示磁性最强 ；相反，当 第二内永磁体与第一内永磁体的异名磁极处于相对应的位置时， 磁力线经 第一铁轭、第二铁轭 顺利穿越， 内部短路，第一铁轭、第二铁轭 对外不显示磁性；根据 第二内磁转子 的旋转角度不同 ， 受磁路改变的影响， 第一铁轭、第二铁轭 对外显示 的磁性从 最 弱变化 到最 强 （或 从 最 强变化 到最 弱 ）。 此种方式相对于改变导体转子与永磁转子的轴向距离来说，降低了磁路调节器的功率消耗，提高了扭矩的传递能力。
所述的磁路调节器包括用于接收控制信号的调节执行器。
所述的调节执行器可为电动执行机构、气动执行机构或液动执行机构。 使用过程中，将永磁调速器安装于某控制系统中，压力、流量、液位或其他控制信号被控制系统接收和处理，然后提供到调节执行器，由调节执行器的执行机构来控制第一内磁转子的转动，改变第一铁轭、第二铁轭对外显示磁性的大小。
本发明 由于采用了固定磁隙结构，大大提高了调速器的啮合面积并降低了装配难度，节约了稀土材料 ， 大大提高了扭矩传递能力 。 由于采用了磁路调节结构，大大减小了执行调节机构的功率消耗并最大限度的缩小了调节执行机构的体积，从而大大缩小了调速器的整体体积，不但降低了材料消耗和节省了安装空间，更是给现场安装施工带来了方便。
