Problems solved by technology

[0003] At present, the stirring torque of the cooking machine at low speed is not enough. Generally, the way of directly increasing the PWM duty cycle is used to increase the torque, but this will cause the motor to be stuck (stall), thereby reducing the whipping performance of the cooking machine.

Abstract

The invention discloses a food processor and a control method and device for preventing a motor from locked-rotor. The method comprises the following steps of: obtaining a rotation speed instruction; analyzing the rotation speed instruction to obtain the target rotation speed of a drive motor, and generating PWM control signals according to the target rotation speed to control the drive motor; in the process of controlling the drive motor, gradually increasing the duty ratio of the PWM control signals in a stepping increment mode, and detecting the rotor position of the drive motor through a Hall sensor to obtain the actual rotation speed of the drive motor; determining whether the actual rotation speed of the drive motor is changed along with the duty ratio increment of the PWM control signals or not; if not, changing the PWM control signals to enable the drive motor to run reversely, and regulating the PWM control signals to control the drive motor to run intermittently in the forward direction to prevent the motor from locked-rotor. Therefore, the motor machinery card pause phenomenon can be effectively reduced, and the whipping performance of the food processor can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a control method for preventing motor stalling of a food cooking machine, a control device for preventing motor stalling of a food cooking machine, and a food cooking machine. Background technique [0002] The cooking machine is a household appliance that integrates the functions of making soybean milk, grinding dry powder, squeezing juice, making meat stuffing, and shaved ice. It is used to make fruit juice, soy milk, jam, dry powder, shaved ice, and meat stuffing. Have to compare the products after diversification. [0003] At present, the stirring torque of the cooking machine at low speed is not enough. Generally, the way of directly increasing the PWM duty cycle is used to increase the torque, but this will cause the motor to be stuck (stall), thereby reducing the whipping performance of the cooking machine. . Contents of the invention [0004] Th...
