Motor applied to blender

Abstract

The invention discloses a motor applied to a blender. A closed air collection hood is arranged on an upper bracket of the motor so as to form an air collection hood integrated bracket, the top of the upper bracket is provided with a bearing housing used for positioning a rotor, and air holes are formed in the bearing housing. During operation, the rotor drives a fan to run, cooling air enters from the top and sequentially passes through the air collection hood integrated bracket, the bearing housing, a clearance between a stator component and the rotor and a lower bracket prior to flowing out, the motor components are cooled one by one, effective cooling of the motor components is realized, temperature rise of the motor is reduced, size of the motor is reduced, damage to the motor components is reduced, and service life of the motor is guaranteed. Meanwhile, the upper bracket and the stator component are connected and fixed via four positioning points distributed evenly, and stability of the motor structure is improved.

Description

technical field [0001] The invention belongs to the technical field of motor structure design, and in particular relates to a motor applied to a mixer. Background technique [0002] Household mixer motors generally use single-phase series-excited motors. Single-phase series-excited motors have the advantages of high speed, small size, and high efficiency, so they are widely used. [0003] A traditional mixer motor includes an upper bracket, a lower bracket, a stator assembly, a rotor and a fan, the stator assembly is arranged between the upper bracket and the lower bracket, and the stator assembly and the upper bracket are positioned through two positioning points. When working, the rotor drives the fan to run. Since the structure of the traditional motor is open, the cooling air generated by the fan is scattered to the outside, and it cannot be concentrated downward to cool the commutator, carbon brushes, bearings and other heat-generating components one by one. The overal...

AI Technical Summary

Problems solved by technology

When working, the rotor drives the fan to run. Since the structure of the traditional motor is open, the cooling air generated by the fan is scattered to the outside, and it cannot be concentrated downward to cool the commutator, carbon brushes, bearings and other heat-generating components one by one. The overall cooling is not good, so the temperature rise of the motor is higher, resulting in an increase in the size of the motor

After a long period of use, the temperature of the motor is high, which is likely to cause problems such as overheating and damage to the internal components of the motor, reduce the working efficiency of the motor, affect the service life of the motor, and increase the cost of maintenance and replacement

[0004] Moreover, only two positioning points are used for positioning between the stator assembly and the upper bracket, the positioning stability of the motor is poor, and it is usually difficult to quickly and effectively confirm the positions of the two positioning points during positioning, and the installation operation is complicated. Assembly inefficiency
