Abstract

The invention discloses an efficient and anti-explosion three-phase asynchronous motor. The efficient and anti-explosion three-phase asynchronous motor comprises a rotor, a stator, a motor shell, an end cover and a current collection ring; a hollow cushioning cavity is formed in one end, towards the end cover, of the motor shell; an air spring is arranged in the hollow cushioning cavity in a sleeving manner; the space between the hollow cushioning cavity and the air spring is filled with a coolant; meanwhile, a coolant inlet and a coolant adding opening are also formed between the motor shell and the hollow cushioning cavity; the coolant inlet and the coolant adding opening are connected with a coolant adding apparatus separately; the coolant adding apparatus is also provided with a temperature control apparatus; the temperature control apparatus is connected with a temperature sensor arranged in the hollow cushioning cavity to realize temperature control to the hollow cushioning cavity; and the air spring comprises a sealed damping section, a cooling compression section and an internal embedding connection section. The three-phase asynchronous motor provided by the invention has a simple structure, a good shakeproof effect, stable operation, relatively high electromechanical conversion efficiency and relatively long service life.

Description

technical field [0001] The invention relates to the explosion-proof technical field of three-phase asynchronous motors, in particular to high-efficiency explosion-proof three-phase asynchronous motors. Background technique [0002] As a three-phase asynchronous motor running as a motor, the rotor speed is lower than that of the rotating magnetic field. The relative motion between the rotor winding and the magnetic field generates electromotive force and current, and interacts with the magnetic field to generate electromagnetic torque to realize energy conversion. [0003] Compared with single-phase asynchronous motors, three-phase asynchronous motors have better running performance and can save various materials. According to different rotor structures, three-phase asynchronous motors can be divided into cage type and wound type. The asynchronous motor with cage rotor has simple structure, reliable operation, light weight and low price, and has been widely used. Its main di...
