Abstract

The invention discloses an explosion-proof three-phase motor, which comprises a base, a shock absorbing mechanism and a motor structure. A fixed side plate is provided, and the center of the protective panel is provided with a front sealing plate, and the center of the front sealing plate is installed with a front rotating shaft, and a first flameproof structure is installed outside the motor structure, and the first flameproof structure is installed There is a second flameproof structure, and a third flameproof structure is arranged outside the second flameproof structure. The invention utilizes the base to reduce vibration buffering and stabilize support, and the middle part of the motor structure is sequentially set with a first explosion-proof structure, a second explosion-proof structure and a third explosion-proof structure. High, and the flameproof strength is higher, the use is safer and more reliable, and the user is more at ease in use. At the same time, the rear part of the motor structure is convenient for heat dissipation.

Description

Technical field [0001] The present invention relates to a motor-related technical field, specifically a flameproof three-phase motor. Background [0002] Three-phase motor refers to when the three-phase stator winding of the motor, each with a difference of 120 degrees of electrical angle, after entering the three-phase alternating current, a rotating magnetic field will be generated, the rotating magnetic field cuts the rotor winding, thereby generating induced current in the rotor winding, the rotor winding is a closed path, the current-carrying rotor conductor will generate electromagnetic force under the action of the stator rotating magnetic field, thereby forming an electromagnetic torque on the motor shaft, driving the motor rotation, and the motor rotation direction is the same as the rotating magnetic field direction. [0003] However, due to the high-speed operation of the three-phase motor of the prior art, the internal temperature is too high, there will be a risk of ...
