Abstract： Aiming poor precision and flexibility of the analog speed control method, a digital speed control scheme for the single-phase motor is proposed. Firstly, the principle of single-phase AC variable voltage speed control is introduced, the main circuit of the controller and the zero-crossing detection circuit are designed, and then the circuit simulation and parameter optimization are carried out. On that basis, an STM32-based variable voltage speed controller for the single-phase motor is built. The zero-crossing detection of supply voltage is accurate. The simulated and experimental results are shown to be in good agreement, verifying the reliability of the digital speed control method.
