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。此外 导体转子转动时与永磁转子产生相对运动， 永磁场在导体转子上产生涡流， 随之产生大量热量，由于导体转子与永磁转子必须存在滑差，调速范围为 0至98%。
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、减小热量产生、增大调速范围的 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，本发明基于磁体同极相斥、异极相吸的原理，从改变外磁转子与内磁转子之间的作用力入手去设计新的永磁调速器，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磁转子以及与从动轴连接的内磁转子，所述的外磁转子沿其内圆周面周向均匀分布有至少一个外永磁体，每个外永磁体的磁极端面与外磁转子端面垂直；所述的内磁转子沿其外圆周面周向均匀分布有至少一个内永磁体，每个内永磁体的磁极端面与内磁转子端面垂直，内永磁体两磁极侧分别固定有铁轭，另外两侧各设有一导磁体，导磁体夹在两铁轭之间，用于与铁轭配合组成将内永磁体包围的闭合磁回路，内磁转子一端设有用于沿轴向移动各导磁体的磁路调节器。 磁路调节器控制导磁体移动来改变导磁体与内永磁体的距离， 调节磁阻大小进而改变内永磁体对外显示的磁性大小，改变内永磁体与外永磁体之间的作用力。导磁体可移动行程不小于铁厄的长度。 具体调节过程： 通过磁路调节器将导磁体移动至可与铁轭组成闭合磁回路的位置，将内永磁体围绕在内时， 磁力线经导磁体顺利穿越， 内部短路，内磁转子 对外不显示磁性 ；当 磁路调节器控制导磁体完全移出两铁轭之间的空隙，铁轭 被磁化成相对应极性的强磁体 当导磁体全部移出内转子铁轭时，内永磁体的磁力对外全部展现，内磁转子对外显示最大磁力；导磁体移出的过程就是内磁转子由无磁力到最大磁力的变化过程；由内磁转子与外磁转子相互作用力的大小变化来实现传递力量的改变，从而实现调速过程。外永磁体的数量可以与内永磁体的数量相同或不同且两者均按照磁极（N极、S极磁体）成对增减。 一般情况下主动轴连接主电机，从动轴连接负载，但两者可以互换，即主动轴连接负载，从动轴连接主电机。
当内磁转子的内永磁体数量和外磁转子的外永磁体数量相等时，可以实现输入、输出转速0~100%的调速功能；当内磁转子的内永磁体量和外磁转子的外永磁体数量不相等时，可以实现输入、输出转速0~N%的调速功能（扭矩随N反比例改变、最大功率不变）。
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。
内、外永磁体的安装方向可以有多种，只要保证内永磁体与外永磁体之间的作用力可调即可，所述的外永磁体和内永磁体的磁极均沿径向设置，两相邻的外永磁体或相邻的内永磁体外露磁极面磁性相异。
两者均围绕从动轴呈圆周分布。
内、外永磁体另一种优选安装方式是： 所述的外永磁体和内永磁体的磁极沿周向设置，两相邻的外永磁体或相邻的内永磁体相邻侧磁极面磁性相异。两者均围绕从动轴呈圆周分布。
所述的磁路调节器包括用于接收控制信号控制导磁体移动的的调节执行器。
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，由调节执行器由其执行机构来移动导磁体，改变磁阻的大小。
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， 降低热量产生，增大调速范围， 节约了稀土材料 ， 大大提高了扭矩传递能力 。由于采用了磁力传递原理，所以实现了 输入、输出转速0~N%的调速功能，大大扩展了本发明的使用范围和领域； 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，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。
