Description

technical field [0001] Embodiments of the present invention relate to cooking equipment design technology, especially a communication device for a food processing machine. Background technique [0002] The current food processors (such as soybean milk machines) all use brushed DC motors. As the food processors are used longer, the carbon powder worn by the carbon brushes of the DC motors will cover the entire circuit controller and the cavity where the entire motor is located. Since carbon powder is conductive, the accumulation of too much carbon powder will bring safety hazards to the food processor. [0003] Using a brushless motor to replace a brushed motor can effectively solve the safety problem caused by toner, and at the same time reduce the noise generated by the operation of the motor body. The application of brushless motors usually uses communication with its main control chip. Since the communication requires two-way communication between the brushless drive uni...
