Motor blades, brushless motors and their rotor assemblies, food processors

Abstract

The invention discloses a motor fan blade, a brushless motor and its rotor assembly, and a food cooking machine. The motor fan blade (11) includes a fan blade body, and the end surface of the fan blade body is arranged at intervals along the circumferential direction. Multiple insertion parts (111a). In the present invention, a plurality of insertion parts arranged at intervals along the circumferential direction are arranged on the end surface of the blade body of the motor blade, so that the motor blade can be built-in and installed on the rotor core, thereby optimizing the motor to have a flat structure , thereby greatly reducing the axial size of the food cooking machine and reducing the vibration and noise generated during its operation. On the other hand, because the motor fan blade of the present invention has a built-in installation structure, the assembly of the rotor assembly is greatly simplified, thereby greatly improving production efficiency, and the production process is clean and pollution-free, and the health of production personnel can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a motor fan blade, a rotor assembly of a brushless motor, a brushless motor and a food cooking machine. Background technique [0002] Existing food processors such as wall breakers or mixers usually generate relatively large vibrations and noises during operation, which greatly affects user experience. To a certain extent, the reason for the large vibration and noise is that the center of gravity of the food processor is too high, and the center of gravity of the food processor is too high mainly because the motor as the power device is equipped with an external motor mounted on the rotor shaft. Fan blades, the existence of the external fan blades will cause the axial size of the motor to increase, resulting in the aforementioned problems of greater vibration and noise. [0003] In addition, the motor rotors in existing food cooking machines mostly use pl...

[0002] Existing food processors such as wall breakers or mixers usually produce relatively large vibration and noise during operation, which greatly affects the user experience

To a certain extent, the reason for the large vibration and noise is that the center of gravity of the food processor is too high, and the center of gravity of the food processor is too high mainly because the motor as the power device is equipped with an external motor mounted on the rotor shaft. Fan blades, the existence of the external fan blades will cause the axial size of the motor to increase, resulting in the above-mentioned problems of greater vibration and noise

[0003] In addition, the motor rotors in existing food processors mostly use plastic-coated or metal end ring structures. The metal end ring structure will increase the axial dimension of the rotor, thereby further increasing the height of the motor.

However, the plastic wrapping process of the rotor is relatively complicated, which is easy to cause dust pollution, and it is difficult to ensure the cleanliness of the processing environment and the health of production personnel.
