Description
Изобретение относитс к способам фиксации останова электроприводов с трехфазными асинхронными двигател ми, имеющими,фазные роторы , путем подачи тока в статор и ротор дл создани в машине неподвижно ориентированного магнитного пол .The invention relates to methods for fixing the stopping of electric drives with three-phase asynchronous motors having phase rotors, by applying current to the stator and the rotor to create a fixedly oriented magnetic field in the machine.
Согласно предложенному способу , обмотки статора и ротора подключают по однофазной схеме к источнику однофазного тока. Это позвол ет увеличить точность фиксации останова электропривода и упростить его эксплуатацию.According to the proposed method, the stator and rotor windings are connected in a single-phase circuit to a single-phase current source. This makes it possible to increase the accuracy of fixing the stop of the electric drive and simplify its operation.
На чертеже показана схема, при помощи которой осуществл етс предложенный способ.The drawing shows the scheme by which the proposed method is carried out.
В ротор ввод т сопротивлени и после снижени скорости двигател контактором Д отключают его от питающей сети. Затем включают контактор /Ci и на обмотки статора и ротора подаетс однофазное напр жение . При этом происходит резкое торможение и фиксированный останов электропривода.Resistances are introduced into the rotor and, after the motor speed is reduced by a contactor D, it is disconnected from the supply network. A contactor / Ci is then turned on and a single-phase voltage is applied to the stator and rotor windings. In this case, there is a sharp braking and a fixed stop of the electric drive.
К источнику однофазного тока можно подключить только обмотку статора, а обмотку ротора, включенную по однофазной схеме, замкнуть накоротко или через сопротивлени .Only the stator winding can be connected to the single-phase current source, and the rotor winding, connected in a single-phase circuit, can be short-circuited or through resistance.
