Electric motor with anti-explosion function

Abstract

The invention discloses an electric motor with an anti-explosion function. The electric motor comprises an anti-explosion shell, wherein the anti-explosion shell comprises a shell wall; the shell wall comprises an inner layer and an outer layer; a hollow cavity is formed between the inner layer and the outer layer; a solid body anti-explosion layer is arranged on one side, far from the outer layer, of the inner layer; a ceramic insulating layer is arranged on one side, far from the inner layer, of the solid body anti-explosion layer; uniformly-arranged heat dissipation sheets are arranged on the outer side face of the anti-explosion shell; a pressure relief cavity and a nitrogen generator are arranged on the top of the anti-explosion shell; an air delivery pipe is arranged on one side, close to the pressure relief cavity, of the nitrogen generator; and a safety relief valve is arranged on one side, close to the nitrogen generator, of the pressure relief cavity. By adoption of the electric motor with the anti-explosion function, the internal pressure of the anti-explosion shell is effectively reduced, so that the explosion probability of the electric motor is lowered, the safety coefficient of the electric motor in use is improved, and the internal temperature of the electric motor is effectively lowered; and even if the electric motor runs for a long time, the internal temperature of the electric motor is not too high, thereby providing effective guarantee to personnel security and property security.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to an electric motor with an explosion-proof function. Background technique [0002] An electric motor is a rotary electric machine that converts electrical energy into mechanical energy. It mainly includes an electromagnet winding or distributed stator winding for generating a magnetic field and a rotating armature or rotor. Under the action of the rotating magnetic field of the stator winding, a current passes through the armature squirrel-cage aluminum frame and is subjected to the action of the magnetic field to make it rotate. There are many defects in the existing electric motors. Excessive internal pressure or excessively high operating temperature for a long time may cause explosion damage to the electric motor, posing threats to personnel and other property. Need a kind of novel technical scheme to solve the above-mentioned problem now. Contents of the invention ...
