Description
Technical field
The invention belongs to technical field of motors, and in particular to a kind of dustless heat dissipation micromotor.
Background technique
Motor (English: Electricmachinery is commonly called as " motor "), which refers to, realizes that electric energy turns according to the law of electromagnetic induction
A kind of calutron for changing or transmitting.It is indicated in circuit with letter M (old plant D).Its main function is to generate driving
Torque, as electrical appliance or the power source of various machinery.Generator is indicated with letter G in circuit.Its main function is benefit
Mechanical energy is converted into electric energy.
But the equipment using motor as power, when work, can all issue fever, these heats are due to motor ventilation
Bad, internal dust is more etc. causes, and when radiating poor, can increase power consumption, heavy then may lead electrizer damage, traditional
Motor be to improve heat dissipation performance, fan is usually set inside motor, is exported to outside blowing by motor to motor
It radiates, enters motor housing due to reducing dust, the side of fan outlet air one end is arranged in the ventilation opening on motor housing more
On wall, negative pressure will form inside motor housing in fan rotation, at this time to the air of motor housing internal flow and to motor
The air of shell exterior flowing passes through ventilation opening, causes the wind-force of fan smaller, heat dissipation performance is poor；If in motor housing circle
Air inlet is set on circumferential surface, is easy to cause dust to enter again when not in use in motor.
Summary of the invention
The problem of mentioning in technology based on the above background, the present invention provides a kind of dustless heat dissipation micromotors, it has
Good thermal diffusivity can avoid dust simultaneously and enter inside motor.
The technical solution adopted by the invention is as follows:
A kind of dustless heat dissipation micromotor, including motor housing and the stator and rotor that are installed on inside motor housing, institute
