Food cooker and its rotation speed increase control method, device

摘要

The present application discloses a food cooker and its rotation speed increase control method and device, and the rotation speed increase control method includes a step of acquiring a rotation speed command and a drive motor when the food cooker is in a no-load or light load state. The PWM control signal is analyzed in the process of analyzing the rotation speed command so as to acquire the target rotation speed of, and generating the PWM control signal based on the target rotation speed so as to control the drive motor, and in the process of controlling the drive motor. The duty ratio of the PWM control signal is gradually increased by the step increment method until the duty ratio of the above reaches 1, and the field weakening control is performed on the drive motor so as to rapidly increase the rotation speed of the drive motor. ,including. The rotation speed increase control method of the embodiment of the present application can make the rotation speed of the drive motor very high within the maximum threshold range allowed for the drive motor.
