Problems solved by technology

During the operation of the motor, a large current is injected into the coil of the stator, so that the coil generates a large amount of heat, and the heat generated continues to accumulate with the growth of time in the future, which makes the temperature inside the motor gradually increase, thus affecting the internal parts of the motor. Working performance also has a great impact on the service life of each part, especially the impact on the circuit board is more obvious, it is easier to damage the electronic components on the circuit board, and even cause the circuit board to burn out
Some existing motors with heat dissipation structure are only suitable for motors with inner stator and outer rotor structure, and the effect is not good for the structure of outer stator stator and rotor

Embodiment 1

[0025] A motor with fast heat dissipation, including a stator 2, a rotor 3 sleeved in the stator, and a rotating shaft 4 pierced on the rotor, and also includes a vent hole 51 on the shell end surface 53 sleeved on the stator that is adapted to each other The shell 5 and the center are provided with a base 6 with a positioning mounting hole column 61, a circuit board 7 is set up on the outside of the base, a drainage fan 8 is fixed on the outside of the end surface of the shell on the rotating shaft, and a plastic seal is placed on the outside of the stator. There is a plastic sealing body 9, the end surface of the plastic sealing body facing the side of the base is integrally connected with a plastic sealing reinforcing connection ring 91 arranged against the side wall of the housing, and the rear end of the housing extends backward and toward Fold in the direction of the rotating shaft to form a fixed riveting pressure limit flap 52 that is pressed against the end face of the...

Embodiment 2

[0033] The difference from the above-mentioned embodiment is that there are several uniform force supporting reinforcing plates 65 connected to the seat plate evenly distributed on the part of the outer peripheral surface of the positioning installation hole column located in the motor.

[0034] The positioning truncated cone is a partially hollowed out truncated cone composed of several inclined strips formed by the partial tilting of the seat plate body to the rear end. The inclined strips are fixed to the rear end of the inclined strips and sleeved on the positioning installation Collar connection on hole post.

[0035] Uniformly supporting the reinforcing plate and the inclined strip improve the torsional strength of the positioning installation hole column from both ends, and ensure the stability of the connection between the rotating shaft and the bearing at this end. And the inclined strip is directly formed by the positioning cone with high strength and convenient proc...

Embodiment 3

[0037] The difference from the above embodiment is that the plastic-encapsulated reinforcing connection ring is a discontinuous ring composed of uniformly distributed plastic-encapsulated protrusions of the fan ring, the seat edge is a plurality of discontinuous edges corresponding to the fan ring, and the plastic-encapsulated reinforcement Locking bolts are also threaded between the connecting ring and the seat edge.

Abstract

The invention relates to the field of motors, and particularly to a quick heat radiation motor. The motor comprises a stator, a rotor which is sleeved in the stator, a rotating shaft which penetrates through the rotor, a housing which sleeves the stator and is provided with ventilating holes on a housing end surface, and a base which is provided with a positioning mounting hole column at the center, wherein the housing and the base are adapted with each other. The outside rack of the base is provided with a circuit board. A drainage fan is fixedly arranged on the rotating shaft at outside of the housing end surface. A plastic sealed member is sealed outside the stator. The end surface, which faces the base, of the plastic sealed member is integrally connected with a plastic sealed reinforcing connecting ring which is arranged in a manner of abutting against the sidewall surface of the housing. Air flow at the back end of the circuit board is sent into the motoring through the circuit board and the ventilating holes on a base board. Similarly, the air flow between the circuit board and the base board is sent into the motor through the ventilating holes on the base board. Heat in the motor is absorbed, and then the heat is quickly leaded out of the motor through ventilating holes of inclined reinforcing hole slot walls. The quick heat radiation motor has advantages of high integrity, compact structure, convenient detachment, low cost, high strength, high stability and low noise.
