Structure and working principle of three-phase asynchronous motor
2026-07-14A three-phase asynchronous motor is a type of electric motor that is powered by simultaneously connecting to a three-phase AC power source (with a phase difference of 120 degrees). Due to the fact that the rotor and stator of a three-phase asynchronous motor rotate in the same direction but at different speeds, there is a slip rate, hence it is called a three-phase asynchronous motor.Working principle: A three-phase asynchronous motor is an induction motor. After a current is applied to the stator, some of the magnetic flux passes through the short-circuit ring and generates induced current in it. The current in the short-circuit ring obstructs the change of magnetic flux, resulting in a phase difference between the magnetic flux generated by the short-circuit ring and the non short-circuit ring, thus forming a rotating magnetic field. After being powered on, the rotor winding induces electromotive force and current due to relative motion with the magnetic field. That is, the rotating

Common faults of asynchronous motor test bench
2026-07-091. Electrochemical destructionIn the gas production workshop of a certain factory, two motors have malfunctioned. One of the stator windings has three insulation ruptures, and an area has "creepage" with burn marks, cracks, and conductive channels. The faulty parts are all near the motor's air inlet and have a tendency to shift towards the dead center. We began to believe that the layout, operating environment, and control methods of the electric motor system were unreasonable, and the harsh operating environment led to electrochemical breakdown.The main cause of insulation damage in asynchronous motor test benches is the electrochemical damage caused by harsh operating environments. The acidic and alkaline corrosive gases present in the environment can corrode the outer layer of insulation materials. In high environments, it can accelerate the performance of insulation materials, and under the dual effects of electricity, heat, and chemistry, it is easy to cause damage.2. Frequent
