降低电机的振动和噪音的方法、装置、控制器及系统
摘要：
本发明提供一种降低电机的振动和噪音的方法、装置、控制器及系统。该方法包括：获取电机的当前运行参数；根据预设的运行参数与谐波电流的幅值及相位角的对应关系，确定该当前运行参数对应的谐波电流的幅值和相位角；将当前运行参数对应的谐波电流注入到所述电机中，以降低所述电机的振动和噪音。由于预先已经设置运行参数与谐波电流的幅值及相位角的对应关系，因此，电机运行过程中，只需要获得电机的当前运行参数，然后根据该对应关系获得该当前运行参数对应的谐波电流的幅值和相位角，直接将当前运行参数对应的谐波电流注入到电机中即可，该方法实施起来简单可行，而且响应速度快，没有延迟，实时性较好。
摘要（英）：

The invention provides a method, device, controller and system for reducing vibration and noise of a motor. The method comprises the steps that a current operating parameter of the motor is obtained; the value of amplitude and the phase angle of a harmonic current corresponding to the current operating parameter are determined according to a corresponding relation of a preset operating parameter and the value of amplitude and the phase angle of the harmonic current; the harmonic current corresponding to the current operating parameter is introduced into the motor so as to reduce the vibration and noise of the motor. Due to the fact that the corresponding relation of the operating parameter and the value of amplitude and the phase angle of the harmonic current is preset, in the motor operating process, only the current operating parameter of the motor needs to be obtained, the value of amplitude and the phase angle of the harmonic current corresponding to the current operating parameter are obtained according to the corresponding relation, and the harmonic current corresponding to the current operating parameter is directly introduced into the motor. The method is easy to implement and feasible, the response speed is high, a delay does not exist, and the realtime performance is good.
