Abstract

An explosion-proof three-phase motor disclosed by the present invention comprises a base, a damping mechanism and a motor structure, the base is provided with the motor structure, the upper end of the middle part of the motor structure is provided with a junction box, the left and right sides of a protection panel are both provided with fixed side plates, and the center of the protection panel is provided with a front sealing plate. A front rotating shaft is installed in the center of the front sealing plate, a first explosion-proof structure is installed outside the motor structure, a second explosion-proof structure is installed outside the first explosion-proof structure, and a third explosion-proof structure is arranged outside the second explosion-proof structure. The base is used for reducing vibration buffering and stabilizing supporting, the middle of the motor structure is sequentially sleeved with the first explosive-proof structure, the second explosive-proof structure and the third explosive-proof structure, and the explosive-proof structures are arranged layer by layer, so that the selected material strength is high, the explosive-proof strength is higher, use is safer and more reliable, and a user uses the explosive-proof structure more safely; and meanwhile, the rear part of the motor structure facilitates heat dissipation.

Description

technical field [0001] The invention relates to the technical field related to motors, in particular to a flameproof three-phase motor. Background technique [0002] Three-phase motor means that when the three-phase stator windings of the motor have a phase difference of 120 degrees, after the three-phase alternating current is connected, a rotating magnetic field will be generated, and the rotating magnetic field will cut the rotor winding, thereby generating an induced current in the rotor winding. The winding is a closed path, and the current-carrying rotor conductor will generate electromagnetic force under the action of the rotating magnetic field of the stator, thereby forming an electromagnetic torque on the motor shaft, driving the motor to rotate, and the direction of rotation of the motor is the same as that of the rotating magnetic field. [0003] However, due to the high-speed operation of the three-phase motor in the prior art, the internal temperature is too hi...
