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

electricalmotor1.blogspot.com winding with dc excitation at work,the stator three

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.

Three-phase asynchronous motor starting method

Three-phase asynchronous motor is divided into squirrel-cage asynchronous motor and wound rotor asynchronous motor,the different structure,the boot method is different also,difference is very big.The start control lines.Squirrel-cage asynchronous motor full pressure start control circuit.Compared with the capacity of 8500w gasoline generatordc motor,asynchronous motor has small volume,light weight,the characteristics of moment of inertia of small.Therefore,in the asynchronous motor has been widely used in industrial and mining enterprises.In many industrial and mining enterprises,the number of squirrel-cage asynchronous motor to about 85% of the total number of electric drive equipment.Under the condition of the transformer capacity allows,squirrel-cage asynchronous motor should be as far as possible directly with full voltage start,can improve the reliability of control circuit,and can reduce electrical maintenance workload.The start of the three-phase asynchronous motor control line The three-phase asynchronous motor has simple structure,reliable operation,strong and

durable,cheap,convenient maintenance and so on a series of advantages.Most of the three-phase

asynchronous motor control line by the contactor,relay,knife switch,button,etc have a mix of contact

electrical appliances.One-way run electrical control circuit Main circuit QS by wholesalemotor.blogspot.com isolation switch,fuse FU,contactor KM normally open contacts,thermal relay FR heat element and motor of M.Control circuit by the starting button SB2,stop button SB1,contactor KM coil and normally open contacts,thermal relay FR normally closed contacts.Control circuit working principle is: 2,press the stop button to stop motor SB1,contactor KM coil electricity,its main contact and auxiliary contact are disconnected,motor from the power and stop operating.At this moment,even if loosen the stop button,because since the lock off contact,contactor KM coil will not electricity,motor will not start on its own. Only once rotor balancing machineagain press the starting button SB2,the motor will start running again.Unidirectional starter motor control circuit used to need only one direction of operation of small power motor control.For example small fan,water pump and belt conveyor and other mechanical equipment.This is one of the most commonly used,the most simple control circuit,can realize the automatic control of start-up and stop of the motor,remote control,frequent operation,etc.
