A motor with fast heat dissipation

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.

Description

technical field [0001] The invention relates to the field of motors, in particular to a motor with fast heat dissipation. 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 s...

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
