I. The concept of PWM and duty-free ratio
①PWM: Also known as pulse width modulation technology, is an analog control mode, the PWM waveform as shown below.
② duty cycle: refers to the proportion of the high level in a period. For example, a duty cycle of 50% means that the high level accounts for half of the period.
Two, PWM fixed frequency speed regulation principle
