Detailed Implementation
[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0016] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, this heat-dissipating motor includes a motor housing 1, a stator 2 and a rotor 3 installed inside the motor housing 1, a motor rear housing 4, and a motor shaft 5. Several heat dissipation grooves 6 for ventilation are provided between the rotor 3 and the motor housing 1. A support plate 7 for supporting the structure of the motor housing 1 is provided inside the motor housing 1. A heat dissipation cavity 8 is provided inside the rear housing of the motor. One end of the motor shaft 5 is connected to the rotor 3, and the other end extends into the heat dissipation cavity 8 and is provided with fan blades 9. Several heat dissipation holes 10 corresponding to the positions of the heat dissipation grooves 6 and interconnected are provided on the support plate 7. Several heat dissipation holes 21 are provided on the support plate 7 at positions similar to those of the rotor 3. Several heat dissipation holes 35 are provided on the motor rear housing 4.
[0017] During motor operation, the rotation of motor shaft 5 drives the fan blades 9 to rotate, causing air inside the motor to be drawn into the heat dissipation cavity 8 and discharged through heat dissipation hole 15. Heat dissipation groove 6 can effectively connect the gas between stator 2 and heat dissipation cavity 8, realizing air circulation on stator 2 and thus completing the heat dissipation of stator 2. Heat dissipation hole 11 corresponds to the position of rotor 3 and can effectively dissipate heat from rotor 3.
[0018] Preferably, the outer side of the motor housing 1 is provided with several slot plates 12, the rear housing 4 of the motor is installed on the outer side of the slot plates 12, and an air inlet slot 13 is provided between the slot plates 12. The air inlet slot 13 is connected to the heat dissipation cavity 8, which greatly increases the air circulation between the heat dissipation cavity 8 and the outside, and avoids the accumulation of heat.
[0019] Preferably, the heat dissipation groove 6 is provided with a plurality of heat-absorbing plates 14 connected to the motor housing 1, which are used to absorb the heat of the stator 2 and prevent heat from accumulating on the stator 2 and causing damage to the stator 2.
[0020] Preferably, the fan blade 9 is installed in the direction of air intake from the front end of the motor.
[0021] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0022] Although this document frequently uses terms such as motor housing 1, stator 2, rotor 3, motor rear housing 4, motor shaft 5, heat dissipation groove 6, support plate 7, heat dissipation cavity 8, fan blade 9, heat dissipation hole one 10, heat dissipation hole two 11, slot plate 12, air inlet slot 13, heat absorption plate 14, and heat dissipation hole three 15, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
