Description

节能电机 技术领域
本发明涉及一种电机，尤其涉及一种节能电机。
背景技术
电机广泛应用百姓生活的方方面面，应用于各行各业。但对于电机的节能，现有的技术，主要以改善电机的通风散热、改善电机的控制驱动电子电路、回收电机的动能转化为电能循环利用等方式实现。
中国专利申请号：201110234966.8，发明名称：大功率节能电机。
中国专利申请号：2015206918229.9，发明名称：智能节能电机。
上述专利文献均是本发明文献前面提到的以改善电机的通风散热、改善电机的控制驱动电子电路、回收电机的动能发电再利用的节能技术使电机节能。
技术问题
众所周知，通电导线周围有磁场。而电机定子上驱动转子转动的驱动线圈，在电机电子换相过程中通过脉冲电流时，驱动线圈的周围也存在变化的磁场。
本发明旨在探索使用上述背景技术的电机节能技术之外的新型电机节能技术，经过长期实验探索，提供一种新型节能电机。
技术解决方案
鉴于上述的背景技术，本发明的课题在于对电机电子换相过程中脉冲电流经过电机的驱动线圈周围产生变化的磁场，通过技术手段将所述的电机驱动线圈周围变化的磁场转换为电能，将所转换的电能存储于电能储存元件中，存储到达一定量后，再利用，从而达到节能。
本发明的实现主要通过下述的技术方案得以解决：
本发明所述的节能电机，包括顶盖、机壳、转子、定子、底盖和电能回收电路。所述的顶盖设有通风口和转轴安装孔。所述的转子上设有转轴，所述的转子内设有永磁体，所述的转子以一定的间隙设置在所述定子的内圆周上；当电能作用在所述定子上时，所述转子通过与定子的相互作用而转动。其特征在于：所述的定子分别设有驱动线圈和磁感应发电线圈，电机电子换相时当变化的脉冲电能通过所述定子上的驱动线圈时，安装在驱动线圈产生变化磁场的作用范围内的磁感应发电线圈同时产生电能，产生的电能经过所述的电能回收电路后再进行使用，从而达到节能。
同时本发明所述的定子上的驱动线圈也具有让电机减速或断电时通过控制电机转动的电 机控制电路进行动能回收发电的功能。
所述的电能回收电路包括整流模块、滤波模块、储存模块、第一开关模块、开关控制模块、第二开关模块、电源适配模块。定子上安装在驱动线圈附近的磁感应发电线圈产生的电能接入整流模块的输入端，整流模块的输出端与滤波模块的输入端相连，滤波模块的输出端与储存模块的输入端相连，储存模块的输出端与第一开关模块的输入端相连，第一开关模块的输出端与后续的负载相连；另一路交流电220V或380V接入电源适配模块的输入端，电源适配模块的输出端与第二开关模块的输入端相连，第二开关模块的输出端与后续的负载相连，开关控制模块分别与第一开关模块、第二开关模块相连。
开关控制模块检测储存模块的电能，储存模块电压大于或等于电源适配模块的电压时，开关控制模块控制第一开关模块导通，同时开关控制模块控制第二开关模块断开。当储存模块电压小于电源适配模块的电压时，开关控制模块控制第一开关模块断开，同时开关控制模块控制第二开关模块导通。
有益效果
使用一种不同于传统电机节能的新型电机节能技术，充分利用了电机驱动线圈周围的变化的磁场，使之转化为电能，对转化的电能进行存储再利用。节能效果持续而且显著，结构和工艺简单，成本低廉，易于推广使用，具有推广使用的价值。
与同类技术方案相比，本发明巧妙地利用电机电子换相时脉冲电流通过驱动线圈产生变化磁场的范围内设磁感应发电线圈发电，而上述的专利方案文献利用传统机械运动的永磁体产生变化的磁场范围内设磁感应发电线圈发电和利用改善通风散热而节能，构思与技术方案完全不相同；在效率上，本发明能高效率的产生电能，在特定的条件下效率与变压器的效率相接近，而上述的专利文献方案易受摩擦和各种阻力的影响，在消耗同等量电能的条件下，本发明回收产生的电能和节能的效果比上述专利文献技术和同类技术方案有显著的提高；与现今广泛应用在电动汽车、电动自行车减速时利用电机上的驱动线圈和电机机械运动磁场变化既能回收动能发电又能帮助减速的技术相比，本发明具有电能持续产生的优点，只要电机上的驱动线圈有变化的电能流过，就能产生相应的回收电能，无论电机加速、减速均能产生电能。
与中国专利申请号：201080044424.8，发明名称：电机，以及同类型的技术相比，该专利文献技术目的用于电机中的分谐波的灵活减小，该专利文献中的所有第M线圈本质上是用来驱动电机转子转动，而本发明的目的和本质是：使磁感应发电线圈用于感应磁场发电再循环利用达到节能，并且效果显著；本发明的目的与该专利文献完全不相同，所要解决现有 技术存在的技术问题也不相同，构思思路也不相同，最终有益效果甚至是相反的。
