Description

Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to a motor with a radial cooling structure. Background Art

[0002] The motor is a commonly used driving component. When the motor is powered on, the motor can drive the transmission component to rotate. During the long-term operation of the motor, the motor will generate more heat. If the heat in the motor cannot be dissipated in time, the aging of the coil in the motor will be accelerated, thereby affecting the service life of the motor. For this reason, the motors currently on the market are equipped with heat dissipation blades or heat dissipation fans at their tails. When the heat dissipation method of heat dissipation blades is adopted, the heat dissipation blades are fixed on the rotating shaft located at the tail of the motor. When the rotating shaft of the motor rotates, the heat dissipation blades can rotate. At this time, the heat dissipation blades can blow air to the housing of the motor, thereby achieving heat dissipation of the motor. When the heat dissipation method of the heat dissipation fan is adopted, the heat dissipation fan is fixed at the tail of the motor. When the heat dissipation fan works, it can blow air to the housing of the motor, thereby achieving heat dissipation of the motor. However, in the above-mentioned motor structure, since the heat dissipation blades or the heat dissipation fan are both located at the tail of the motor, whether the heat dissipation blades or the heat dissipation fan are used to dissipate the heat of the motor, the size of the motor in the axial direction will be increased, that is, when the motor is installed and used, there will be a disadvantage that the motor occupies a large axial space. Summary of the invention
