Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: when the motor of the fan is stored in a humid environment for a long time, water vapor will easily enter the casing, making the internal structure of the motor wet with water. The smaller the resistance, the insulation breakdown of the motor coil will easily cause the motor to burn out and shorten the service life of the motor

Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] refer to figure 1 , is a three-phase asynchronous motor for an explosion-proof fan disclosed in the present invention, including a motor body 1, a casing 2 sleeved outside the motor body 1, a fan blade 13 fixed coaxially with the output shaft of the motor body 1, and a set A dehumidification mechanism 3 on the motor body 1 for dehumidification. There are three fan blades 13 and they are distributed at equiangular intervals around the output shaft of the motor body 1. When the motor body 1 rotates, the fan blades 13 are driven to rotate, so as to play the role of ventilation and realize the effect of a fan.

[0037] The casing 2 includes a base 14 welded and fixed on the top of the motor body 1 , and two ventilation covers 22 hinged to the base 14 . Two ventilation covers 22 are symmetrically distributed along the base 14 and rotate in opposite direct...

Abstract

The invention relates to a three-phase asynchronous motor for an explosion-proof fan, and relates to the technical filed of motors. The three-phase asynchronous motor comprises a motor body, a case sleeving the motor body, fan blades coaxially fixed to an output shaft of the motor body, and a dehumidification mechanism arranged on the motor body and used for dehumidification; and the dehumidification mechanism comprises a plurality of heating sheets arranged on the inner wall of the case and distributed around the circumferential side of the motor body at equal angles, a plurality of gas holesare formed in the motor body in the two axial ends of the motor body, a heat conducting layer is arranged between the heating sheets and the motor body, the gas holes are opposite to the fan blades,and a plurality of convection holes are formed in the circumferential surface of the motor body. The three-phase asynchronous motor has the effect that the motor burnout accident caused by the fact that the motor is affected by the damp is avoided, so that the service life of the motor is prolonged.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a three-phase asynchronous motor for an explosion-proof fan. Background technique [0002] Currently, electric motors are widely used in homes and factories. The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machines. The motor is mainly composed of a frame, a stator, a stator winding, a rotor and other structures. After the stator winding is energized to generate a magnetic field, it drives the rotor to rotate to rotate the output shaft of the motor, thereby driving other equipment connected to its output shaft to operate. Three-phase asynchronous motor is a kind of motor, which is a type of motor powered by simultaneous access to 380V three-phase AC current (phase difference...
