Description

TECHNICAL FIELD

[0001] The utility model relates to a series excited motor technology, specifically, a series excited motor for a wall breaking machine. BACKGROUND

[0002] A wall breaking machine is a kind of high-efficiency kitchen appliance, mainly used for beating various food materials (such as nuts, seeds, fruits and vegetables) into fine powder or slurry. In order to achieve this goal, the wall breaking machine needs to have a powerful power system to drive its blades to rotate at high speed, so as to realize the fine grinding and mixing of food materials. This efficient grinding and mixing capacity enables the wall breaking machine to easily process food materials of various hardness and texture, meeting the diversified cooking needs of users.

[0003] The series excited motor (also known as series motor) is a commonly used type of motor in the wall breaking machine. The characteristic of this motor is that its stator winding and rotor winding are connected in series, which can work by direct current or alternating current. The series excited motor has high starting torque and good speed regulation performance, which enables it to start quickly and maintain stable operation under different load conditions.

[0004] However, the existing series excited motor for the wall breaking machine generates a large amount of heat during operation. This overheating phenomenon not only affects the performance of the motor, but also can cause damage to the motor, shortening its service life. In order to solve this problem, some wall breaking machines connect fan blades on the output shaft of the motor. When the motor operates, the fan blades rotate with the output shaft, helping the motor to dissipate heat through air flow. Although this method can alleviate the overheating problem to some extent, the effect of heat dissipation by fan blades alone is not particularly ideal. In the case of high load or long time operation, the heat dissipation by fan blades alone often cannot fully meet the heat dissipation needs of the motor, which may still cause the motor to overheat.

[0005] At present, there is no effective solution to the problems in the related technology. UTILITY MODEL CONTENTS
