Efficient dustproof EC motor

Abstract

The invention discloses an efficient dustproof EC motor in the technical field of mechanical equipment. The motor comprises a front cover, a rear cover and a motor shell, a through hole is formed in the middle of the top of the front cover; a bearing sleeve is welded to the top of an inner cavity of the front cover through ultrasonic waves. A bearing is embedded in the bearing sleeve; the rear cover is positioned at the bottom of the front cover; the rear cover and the front cover are welded through ultrasonic waves; an AC-DC power supply is fixed to the bottom of an inner cavity of the rear cover through bolts, an AC-DC conversion plate is inlaid in the inner side wall of the rear cover, the AC-DC conversion plate is in electrical input connection with the AC-DC power supply, a stator base is inlaid in the bottom of the inner cavity of the rear cover, and the upper portion of the stator base extends to the inner cavity of the front cover; the alternating-current and direct-current conversion plate, the brushless circuit board and the circuit element are installed in the front cover and the rear cover, intelligent control over the motor can be conveniently achieved through cooperation of the alternating-current and direct-current conversion plate, the brushless circuit board and the circuit element, forward and reverse rotation circulating operation of the motor is controlled,and the use requirement of a fresh air system can be well met.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to an efficient dust-proof EC motor. Background technique [0002] A motor is a device that converts electrical energy into mechanical energy. It uses energized coils (that is, stator windings) to generate a rotating magnetic field and acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magneto-electric power rotation torque. Motors are divided into DC motors and AC motors according to the power used. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (the motor stator magnetic field speed and rotor rotation speed do not maintain synchronous speed). The motor is mainly composed of a stator and a rotor. The direction of the current-carrying wire in the magnetic field is related to the direction of the current and the direction of the magnetic field line (magnetic field direction). The wor...

Problems solved by technology

[0003] The purpose of the present invention is to provide a high-efficiency dust-proof EC motor to solve the problem that the motor proposed in the background technology has a low degree of intelligent control during use; and the motor has poor sealing performance, and the dust in the air passes through the gaps. Into the inner cavity of the motor, attached to the surface of the circuit components will affect its use; and the vibration damping effect of the rotating shaft is poor when rotating, which will affect the stability of the rotating shaft
