Abstract

The invention discloses a dual high voltage flameproof motor, which comprises a shell; a spindle, a rotor and a stator are arranged in the shell; the rotor is fixed on the spindle; the front and the back of the shell are respectively provided with a front end cover and a back end cover; front and back ends of the spindle are rotationally connected with the front and back end covers through bearings; the shell is provided with a junction box; the junction box is provided with a junction box cover and a power cord inlet; a terminal board is arranged in the junction box, and is provided with a terminal which is connected with the stator through a wire; a junction face of the front end cover and the shell, a junction face of the back end cover and the shell, the junction face of the junction box and the shell; the junction face of the front end cover and the spindle, a junction face of the junction box and the terminal board, a junction face of the terminal and the terminal board, and a junction face of the junction box cover and the junction box are all flameproof faces; and the stator is fixedly connected with the shell through a flat screw. The dual high voltage flameproof motor has the advantages of compact structure, small volume, light weight, low noise, small vibration, low energy consumption, high output power and easy promotion and application.

Description

technical field [0001] The invention relates to a motor, in particular to a double high voltage flameproof motor. Background technique [0002] The flameproof three-phase asynchronous motor used in the power source of the existing general flameproof propeller is widely used in my country's coal mine, petroleum, chemical industry and other industries, but the efficiency and power factor of this common flameproof motor are relatively low , high energy consumption, relatively large volume of the motor, which caused great waste to the user unit, failed to achieve the goal of energy saving and high efficiency advocated by the state, and ordinary motors cannot be used with propellers, and cannot be used in occasions containing explosive gases . In addition, the stator of the existing flameproof motor is fixed by clamping the casing. After a long time of operation, the stator will loosen when the rotor rotates at high speed, which will affect the working efficiency. Contents of th...
