Description

一种无制动转矩恒空载发电机
技术领域
本发明涉及一种现有同步发电机改进技术, 特別是对同步发电机 的旋转磁极转子进行突破性改进的无制动转矩恒空载发电机。 背景技术
电机和电机学, 已经是一门非常成熟和广泛的实用技术。 但迄今 为止所有发电机的旋转磁极转子部分的转动轴与磁极都是整体制造; 见 《电机工程手册》 第三卷(电机卷) 第二版电.机工程手册编辑委员 会, 机械工业出版社 1996年出版。 转动轴与磁极之间没有相对运动。 这样一来, 当发电机在原动机拖动下, 向负载输出电能和功率时, 原 动机的拖动转矩都必须克服制动的电磁转矩和空载的机械转矩, 才能 发出电来, 这就造成了发电机的工作效率低问题。 发明内容
本发明的目的是为了解决上述问题, 设计了一种无制动转矩恒空 载发电机 。
实现上述目的本发明的技术方案为, 一种无制动转矩恒空栽发电 机, 所述发电机的磁极转子是由各自单个且能沿中心轴滑动的磁极块 组成的。
每个所述磁极块都设有定位轴在转盘架上的圆弧轨道槽中。
所述转盘架边缘处设有轴承滑轮和钢丝绳引出孔。
钢丝绳一端紧固套在定位轴上, 另一端由钢丝绳引出孔引出后固 定。
本发明与现有技术相比具有以下有益效果: 无论制动转矩怎么增 大, 只要在钢丝绳的机械承受范围内; 所有制动电磁转矩都最终作用 :在中心轴上; 从而使制动转矩相对原动机的拖动转矩永远为零。 附图说明
图 1是本发明所述无制动转矩恒空载发电机的转子部分的剖面图; 图 2是本发明所述无制动转矩恒空载发电机的转子部分中 AA处的 A-A旋转图;
图 3是本图 1所述无制动转矩恒空载发电机的 BB处的 B-B旋转图; 图中, 1、 磁极块; 2、 定位轴; 3、 转盘架; 4、 圆弧轨道槽; 5、 中心 轴。 6、 轴承滑轮; 7、 钢丝绳; 8、 钢丝绳引出孔。 具体实施方式
为便于本发明技术方案的理解, 下面结合具体的实施方式进行介 绍。 如图 1和图 2所示, 一种无制动转矩恒空载发电机, 所述发电机 的磁极转子是由各自单个且能沿中心轴 5滑动的磁极块 1组成的。 其 中, 每个所述磁极块都设有定位轴 1在转盘架 3上的圓弧轨道槽 4中; 转盘架边缘处设有轴承滑轮 6和钢丝绳引出孔 8 ;钢丝绳 7—端紧固套 在定位轴上, 另一端由钢丝绳引出孔引出后固定。
在图 1和图 2中磁极块可以是整块永磁材料, 也可以是瓦形永磁 材料粘贴于由硅钢片叠加而成的磁极块; 如果是励磁磁极则要考虑励 磁线圈的引出和集电环的装配。 每个定位轴两端在两圓弧轨道槽中尽 可精密衔接, 圆弧轨道槽长并不需要太大, 仅 2倍定位轴直径即可; 转盘架应当采用整体铸造成型然后再精密加工而成, 直径大于定子而 小于外壳, 并考虑在上面设置通风窗; 如果是励磁方式磁极还要考虑 前转盘架(附图 1的上端转盘架) 集电环的安装和电机外壳布置电刷。 这对于专业技术人员来说也是不难做到的事情。 是电机设计时必然要 考虑的事情。 对于图 3中钢丝绳的具体走法与引出后怎样固定, 由于 方式可以各式各样和电机大小不同, 因此这里也不详细说明; 这里需 要特别说明关键的是: 16根钢丝绳中的每根钢丝绳都必须拉力均匀和 适度, 每根钢丝绳都必须:经拉力计读数一致, 必要时考虑钢丝绳索具 进行调节。 这样当原动机拖动发电机转盘架上的整个转子磁极在定子的绕组 中 (图中是以 4 个磁极并以顺时针拖动方向为讨论基础)旋转时, 便 切割定子上的绕组线圈产生感应电势, 当这些绕组线圈通过接线端子 引出, 连接负载回路中时, 便产生了电流。 由左右手法则可知, 每个 磁极的制动电磁转矩都会产生反时针方向的制动转矩。 而且这个制动 电磁转矩是随着输出负载电流的增加, 制动转矩的增大。 但对于本技 术而言, 无论制动转矩怎么增大, 只要在钢丝绳的机械承受范围内; 所有制动电磁转矩都最终作用在中心轴上; 从而使制动转矩相对原动 机的拖动转矩永远为零。
总之, 电机的机械制造技术和电机制造工艺现在已经是一门相当 成熟的实用技术, 本发明仅是在这些现有技术的基础上, 对磁极的转 子部分着一些简单的机械改进。 因此, 本发明的制造技术和制造工艺 也完全是建立在现有制造技术的基础之上, 生产工艺并没有特别之处。 一般专业技术人员不需要经过特别知识都能处理。
上述技术方案仅体现了本发明技术方案的优选技术方案, 本技术 领域的技术人员对其中某些部分所可能做出的一些变动均体现了本发 明的原理, 属于发明的保护范围之内。
