Motor blade, brushless motor, rotor assembly of brushless motor and food processor

Abstract

The invention discloses a motor blade, a brushless motor, a rotor assembly of the brushless motor and a food processor. The motor blade (11) comprises a blade body, wherein a plurality of insertion parts (111a) are arranged on an end surface of the blade body at intervals along a circumferential direction. By arranging the plurality of insertion parts on the end surface of the blade body of the motor blade at intervals along the circumferential direction, the motor blade can be internally arranged on a rotor core, so that the motor is optimized to be a flat structure, the axial size of the food processor is greatly reduced, and the vibration and the noise generated by the working process of the food processor are reduced; and on the other hand, the motor blade is provided with a built-in installation structure, the assembly of the rotor assembly can be greatly simplified, the production efficiency is greatly improved, moreover, the production process is clean, no pollution is generated, and the health of a producer 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.
