EC电机bai是三相交流永磁同步电机。EC 电机电源为直流电源、内置直流变交流（通过六个逆变模块）、采用转子位置反馈、三相交流、永磁、同步电机。

EC电机为内置智能控制模块的直流无刷式免维护型电机，自带RS485输出接口、0-10V传感器输出接口、4-20mA调速开关输出接口、报警装置输出接口及主从信号输出接口。该产品具有高智能、高节能、高效率、寿命长、振动小、噪声低以及可连续不间断工作等特点。

无刷直流电机由于省去了励磁用的集电环和电刷，在结构上大大简化。同时不但改善了电机的工艺性，而且电机运行的机械可靠性大为增强，寿命增加。
同时气隙磁密可大大提高，电机指标可实现*佳设计，其直接效果就是电机体积缩小，重量减轻。不仅如此，较其它电机而言，还具有非常优异的控制性能。这是因为：其一，由于永磁材料的高性能而使电机的力矩常数、转矩惯量比、功率密度等大大提高。通过合理设计又能使转动惯量、电气及机械时间常数等指标大大降低，作为伺服控制性能的主要指标有了很大改善。其二，现代永磁磁路的设计已较完善，加上永磁材料的矫顽力高，因而永磁电机的抗电枢反应及其抗去磁的能力大大加强，电机的控制参量随外部扰动影响大大减小。其三，由于用永磁体取代了电励磁，减少了励磁绕组及励磁磁场的设计，因而减少了励磁磁通、励磁绕组电感、励磁电流等诸多参数，从而直接减少了可控变量或参量。综合以上各因素可以说永磁电机具有优异的可控性。

无刷直流电动机需要矩形波电流，逆变器持续运行时的电流额定值指的就是这个矩形波的峰值。感应电机需要正弦波电流，逆变器持续运行时的电流额定值一般指的是这个正弦波的有效值。为保持逆变器对电动机电流的控制能力，逆变器直流电压与电动机感应电动势间应有足够的差值。因此无刷直流电动机梯形波感应电动势和感应电动机正弦波感应电动势可以达到的峰值都受到逆变器直流电压的限制。在这种情况下，若假定无刷直流电动机和感应电动机电流的峰值相等，则前者功率输出要比后者高出33%，也就是说，同一台整流器/逆变器可以驱动比感应电机输出功率高出33%的无刷直流电动机。

无刷直流电动机是采用半导体开关器件来实现电子换向的，即用电子开关器件代替传统的接触式换向器和电刷。它具有可靠性高、无换向火花、机械噪声低等优点，广泛应用于高档录音座、录像机、电子仪器及自动化办公设备中。
无刷直流电动机由永磁体转子、多极绕组定子、位置传感器等组成。位置传感按转子位置的变化，沿着一定次序对定子绕组的电流进行换流（即检测转子磁极相对定子绕组的位置，并在确定的位置处产生位置传感信号，经信号转换电路处理后去控制功率开关电路，按一定的逻辑关系进行绕组电流切换）。定子绕组的工作电压由位置传感器输出控制的电子开关电路提供。

位置传感器有磁敏式、光电式和电磁式三种类型。
采用磁敏式位置传感器的无刷直流电动机，其磁敏传感器件（例如霍尔元件、磁敏二极管、磁敏诂极管、磁敏电阻器或专用集成电路等）装在定子组件上，用来检测永磁体、转子旋转时产生的磁场变化。
采用光电式位置传感器的无刷直流电动机，在定子组件上按一定位置配置了光电传感器件，转子上装有遮光板，光源为发光二极管或小灯泡。转子旋转时，由于遮光板的作用，定子上的光敏元器件将会按一定频率间歇间生脉冲信号。
采用电磁式位置传感器的无刷直流电动机，是在定子组件上安装有电磁传感器部件（例如耦合变压器、接近开关、LC谐振电路等），当永磁体转子位置发生变化时，电磁效应将使电磁传感器产生高频调制信号（其幅值随转子位置而变化）。

直流电机具有响应快速、较大的起动转矩、从零转速至额定转速具备可提供额定转矩的性能，但直流电机的优点也正是它的缺点，因为直流电机要产生额定负载下恒定转矩的性能，则电枢磁场与转子磁场须恒维持90°，这就要藉由碳刷及整流子。碳刷及整流子在电机转动时会产生火花、碳粉因此除了会造成组件损坏之外，使用场合也受到限制。交流电机没有碳刷及整流子，免维护、坚固、应用广，但特性上若要达到相当于直流电机的性能须用复杂控制技术才能达到。现今半导体发展迅速功率组件切换频率加快许多，提升驱动电机的性能。微处理机速度亦越来越快，可实现将交流电机控制置于一旋转的两轴直交坐标系统中，适当控制交流电机在两轴电流分量，达到类似直流电机控制并有与直流电机相当的性能。

直流无刷电机是同步电机的一种，也就是说电机转子的转速受电机定子旋转磁场的速度及转子极数(p)影响。在转子极数固定情况下，改变定子旋转磁场的频率就可以改变转子的转速。直流无刷电机即是将同步电机加上电子式控制(驱动器)，控制定子旋转磁场的频率并将电机转子的转速回授至控制中心反复校正，以期达到接近直流电机特性的方式。也就是说直流无刷电机能够在额定负载范围内当负载变化时仍可以控制电机转子维持一定的转速。

要让电机转动起来，首先控制部就必须根据hall-sensor感应到的电机转子目前所在位置，然后依照定子绕线决定开启(或关闭)换流器(inverter)中功率晶体管的顺序，使电流依序流经电机线圈产生顺向(或逆向)旋转磁场，并与转子的磁铁相互作用，如此就能使电机顺时/逆时转动。当电机转子转动到hall-sensor感应出另一组信号的位置时，控制部又再开启下一组功率晶体管，如此循环电机就可以依同一方向继续转动直到控制部决定要电机转子停止则关闭功率晶体管(或只开下臂功率晶体管)；要电机转子反向则功率晶体管开启顺序相反。
