Description

一种搭载磁编传感器正弦波控制电机 技术领域
本发明涉及一种搭载磁编传感器正弦波控制电机，属于电机技术领域。
背景技术
目前，由于优良的特性，良好的性价比，在我公司技术变革的带动下，三轮车电机正弦波控制技术越来越发展壮大，其优越性不断得到市场认可。现有正弦波控制技术采用磁钢“V”字型对称分布，内嵌式安装，能很好的降低电机长时间运行后带来的温升磁损，提高电机稳定性，同时采用霍尔固定方式，将磁偏角固化，降低操作难度，提高工作效率。居安思危，怎样更好的发挥正弦波控制技术的优势，怎样在竞争日益激烈的市场中独占鳌头，继续引领行业潮流，我公司从未停止办法，不断开阔进取。
目前，正弦波技术共有霍尔外置和霍尔内置两种方式。霍尔外置时易受定子磁场干扰，而且转子两磁极间分界线不规律、不明晰，易造成霍尔信号抖动，从而影响电机运行稳定和工作效率。
我公司基于正弦波控制程序，再次探索，于2015年研发出适用性更强的霍尔内置型正弦波电机。该方案对霍尔角度进行先期固化安装，从而提高电机运行的精确性、一致性，大大简化了生产工艺和操作流程。
但是在三轮车市场上，由于客户认知水平不断提高，对产品性能要求刚加严格，本发明旨在开辟正弦波控制技术新的控制方式，改变现有单一依靠霍尔元件的的控制现状，提高与对应正弦波控制器的匹配效果，提高正弦波电机运行稳定性能。
发明内容
本发明针对上述问题的不足，提出一种搭载磁编传感器正弦波控制电机，摒除原有单一依靠霍尔元件进行电机信号采集，引入一种磁编传感器，进行电机信号的感应，电机信号控制精确性高。
本发明为解决上述技术问题提出的技术方案是：
一种搭载磁编传感器正弦波控制电机，包括磁编传感器安装室(2)，所述磁编传感器安装室(2)上设置有盖板安装孔(1)和磁编传感器固定孔(4)；且所述磁编传感器安装室(2)的中心开设有用于中心驱动轴(3)穿过的通孔；所述盖板安装孔(1)沿磁编传感器安装室(2)的周向分布；所述磁编传感器放置于磁编传感器安装室(2)内，且所述磁编传感器通过磁编传感器固定孔(4)固定于磁编传感器安装室(2)中；所述 磁编传感器安装室(2)安装在电机外部减速箱(5)的侧面。
优选的：所述盖板安装孔(1)沿磁编传感器安装室(2)的周向均匀分布。
优选的：所述盖板安装孔(1)有三个。
优选的：所述磁编传感器固定孔(4)有两个。
本发明相比现有技术，具有以下有益效果：
本发明摒除原有单一依靠霍尔元件进行电机信号采集，引入一种磁编传感器，进行电机信号的感应。由于磁编传感器灵敏度高，分辨率可达1024，而现有霍尔元件分辨率只有24，因此电机信号控制精确性根本性提高。

图1是本发明磁编传感器安装室的结构示意图；
图2是磁编传感器安装室安装在电机上的结构示意图。
具体实施方式
