The harmonic reducer is driven by a motor to achieve speed control of the output shaft, and the speed can be controlled by the input power or through a frequency converter. A frequency converter is an electronic converter that changes the frequency of the output voltage to change the speed of the motor and achieve control.
For example, when it is necessary to increase the speed of the output shaft, the input voltage of the motor can be increased or the output frequency can be increased through a frequency converter. When it is necessary to reduce the speed of the output shaft, it is necessary to lower the input voltage of the motor or reduce the output frequency through a frequency converter.
