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

[0029] A high-speed, fast heat-conducting motor, including a stator 2, a rotor 3 sleeved in the stator, and a rotating shaft 4 pierced on the rotor, and a shell end surface 53 sleeved on the stator that is adapted to each other. The housing 5 of the air hole 51 and the center are provided with a base 6 for positioning and installing hole columns 61. A circuit board 7 is erected on the outside of the base. A plastic seal body 9 is plastic-sealed on the top, and the end surface of the plastic seal body facing the base side is integrally provided with a ring of plastic seal reinforcing connection ring 91 which is attached to the side wall of the housing, and the rear end of the housing extends backward. And turn over to the direction of the rotating shaft to form a fixed riveting pressure limit flap 52 pressed against the end face of the plastic seal reinforcement connection ring, the base includes a seat plate 62 provided with a number of ventilation holes and a seat plate 62 tha...

Embodiment 2

[0037] 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.

[0038] 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.

[0039] 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

[0041] 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 a motor, and specifically relates to a high-rotation speed and rapid heat-conduction motor. The motor comprises a stator, a rotor sleeved in the stator and a rotation shaft penetrating the rotor. The motor also comprises a shell and a base which fit with each other. The shell sleevesthe stator. Vent holes are arranged on a shell end face. A positioning and installing hole post is arranged at the center of the base. A circuit board is arranged on an outer side frame of the base. A drainage fan is fixedly arranged on the rotation shaft and is located at the outer side of the shell end face. A plastic package body is packaged out of the stator. A plastic package reinforcing connection ring is integrally connected with the end face of one side of the plastic package body facing towards the base. The plastic package reinforcing connection ring is arranged against the side wall face of the shell. Airflow at the rear end of the circuit board is sent in the motor through the circuit board and the vent holes on a base plate. Equally, the airflow between the circuit board and the base plate is sent in the motor through the vent holes on the base plate, then the heat in the motor is absorbed by the airflow, and then the airflow is rapidly exported out of the motor through vent holes on an incline reinforced hole slot wall. The whole motor has the advantages of high integrity, compact structure, convenient disassembly, low cost, high strength, high stability and low noise.
