The working principle of the three-phase asynchronous motor

Working principle of the three-phase asynchronous motor is as follows:Symmetrical three phase winding ventilation with symmetrical three phase current,to produce a rotating magnetic field,magnetic field line cutting rotor winding,according to the principle of electromagnetic induction,rotor winding of e and I,rotor winding by the effect of electromagnetic force in the magnetic field,electromagnetic torque,which make the rotor rotation,the rotor output mechanical energy,drive the mechanical load.The rotor asynchronous motor rotating speed n Say again synchronous motor below:Synchronous motor as a generator running,the rotor winding with dc excitation at work,by external mechanical force to drive the rotor rotation,the direction of the n0 and torque T direction on the contrary,the stator of the induced emf (electromagnetic induction principle),and then the output voltage.Run-time synchronous motor for motor,rotor

phase alternating current (ac),to produce a rotating magnetic field,drive the rotor synchronous

rotation.Widely used three-phase asynchronous motor,but after running through a long time,can produce all kinds of fault,www.facebook.com/guohong.trading determine the cause of the

problem in time,the corresponding processing,is to prevent failure,ensure the normal operation of

equipment is an important work.Additional information:Generator in the form of a lot of,but its

working principle is motor lamination based on the law of electromagnetic induction

and electromagnetic force law.Therefore,the construction of the general principle is: use the

appropriate magnetic and conductive material electromagnetic induction of the magnetic circuit and

electric circuit with each other,to produce electromagnetic power,achieve the goal of energy

conversion.
