【技术】无刷电机的三种控制方法
无刷电机有三种控制方式:方波控制、正弦波控制和FOC控制。在调整控制器的电流和电压时,应注意调整康斯坦坦的长度和电源连接的电阻,本文富兴机电(FULLING MOTOR)具体介绍无刷电机的控制模式和基本维护。
1.方波控制
方波控制使用无刷电机霍尔效应传感器或无传感器估计算法获得电机转子位置,然后根据转子位置在360°的电气循环中进行6次(每60°)。电机的每个换向位置在特定方向上输出一个力,因此可以说方波控制位置的电气精度为60°。由于该控制下电机的相电流波形接近方波,因此称为方波控制。其优点是控制算法简单,硬件成本低,使用普通性能控制器可以获得更高的电机转速;缺点是转矩波动,存在一定的电流噪声,效率不能达到最大值。方波控制适用于旋转性能要求不高的无刷电机。
2.正弦波控制
正弦波控制方法采用SVPWM波,输出为三相正弦波电压,相应的电流也为正弦波电流。这样,就不存在方波控制换向的概念,也不存在一个电循环被无限多次执行的概念。显然,与方波控制相比,正弦波控制具有更小的转矩脉动和更小的电流谐波,这使得控制感觉更“精致”,但控制器的性能略高于方波控制,无刷电机效率无法发挥到峰值。
3.FOC控制
正弦波控制间接实现了电压矢量的控制和电流的控制,但不能控制电流的方向。FOC控制方法实现了电流矢量控制,即无刷电机定子磁场矢量控制。
