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

[0030] A long-life safety motor, 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, and 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 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 plastic-seal...

Embodiment 2

[0039] 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.

[0040] 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.

[0041] 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

[0043] 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 specifically relates to a long-life safety motor. The motor comprises a stator, a rotor sleeved in the stator and a rotating shaft penetrating through the rotor, and further comprises a shell adaptively sleeved on a shell end face of the stator and provided with a vent hole and a base in the center of which a positioning installation hole post is arranged, wherein a circuit board is arranged on the outer side of the base, a draught fan is fixedly arranged on the rotating shaft and on the outer side of the shell end face, a plastic packaging body is packaged outside the stator, and a plastic packaging reinforcing connecting ring attached to the side wall of the shell is arranged on the end face of one side of the plastic packaging body facing the base in an integrated connection mode. Airflow at the rear end of the circuit board is fed into the motor via the circuit board and the vent hole in the bottom plate, the airflow between the circuit board and the bottom plate is also fed into the motor via the vent hole in the bottom plate, then the heat in the motor is absorbed, and the heat is quickly guided out of the motor via the vent hole in the inclined reinforcing hole slot wall. The whole motor has the advantages of strong integrality, compact structure, convenience in disassembly and assembly, low cost, high strength, good stability and low noise.

Description

technical field [0001] The invention relates to the field of motors, in particular to a long-life and safe motor. Background technique [0002] At present, motors are widely used in electronics and automation equipment industries. 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, making 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. Existing motors with heat dissipation structures are only suitable for motors with inner stator and outer rotor structures, and are not effective for outer stator st...
