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

[0027] A motor with high circuit board safety, 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 that is sleeved on the stator that is adapted to each other. The housing 5 of the ventilation hole 51 and the center are provided with a base 6 for positioning and installing hole columns 61, and a circuit board 7 is erected on the outside of the base, and a drainage fan 8 is fixed on the outside of the end surface of the housing on the rotating shaft. The outer plastic seal has a plastic seal body 9, 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 ...

Embodiment 2

[0035] 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.

[0036] The positioning truncated cone is a partially hollowed out truncated cone composed of a number of 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.

[0037] 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 ...

Embodiment 3

[0039]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 in particular relates to a motor having high circuit board security. The motor comprises a stator, a rotor and a rotating shaft, wherein the rotor sleeves in the stator; the rotating shaft is arranged on the rotor in a penetrating manner; the motor further comprises a shell and a base, wherein the shell and the base are mutually adapted; the shell sleeves the shell end face on the stator and is provided with a ventilation hole; a locating installation hole column is arranged in the centre of the base; a circuit board is arranged outside the base in a bridging manner; a drainage fan is fixedly arranged on the rotating shaft and outside the shell end face; a plastic package body is packaged outside the stator; a plastic package enhanced connection ring arranged to lean on the side wall surface of the shell is arranged on the plastic package body towards the end face at one side of the base in an integral connection manner; an airflow at the rear end of the circuit board is fed into the motor through the circuit board and the ventilation hole on the bottom plate; same, an airflow between the circuit board and the bottom plate is fed into the motor through the ventilation hole on the bottom plate; and then, heat in the motor is absorbed and rapidly output from the motor through the ventilation hole on an inclined enhancement hole arrangement groove wall. The whole motor has the advantages of being high in integrality, compact in structure, convenient to assemble and disassemble, low in cost, high in strength, good in stability and low in noise.
