Description

Известные способы стабилизации посто нных магнитов системыKnown methods of stabilizing permanent magnets of a system

возбуждени  реверсируемых двигате чей посто нного тока основаны наexcitation of a reversible motor whose direct current is based on

том, что испытываемую электрическую машину заставл ют работатьthat the electric machine under test is made to work

-В режиме короткого замыкани  с возбуждением от посто нных магнитои-In short circuit mode with permanent magnet excitation

при номинальном напр жении.at rated voltage.

Однако эти способы не учитывают вли ни  размагничиваюш.их ампер-витков , возникающих при реверсе двигател .However, these methods do not take into account the influence of either demagnetizing ampere turns arising from the reverse of the engine.

Предлагаемый способ -.стабилизации более совершенен, так как on лишен указанного недостатка.The proposed method — stabilization is more perfect, since on is deprived of the indicated disadvantage.

Это достигаетс  тем, что стабилизаци  посто нных магнитов производитс  путем периодического реверсировани  двигател , на валу которого устанавливаетс  маховик.This is achieved by stabilizing the permanent magnets by periodically reversing the engine on whose shaft a flywheel is mounted.

При стабилизации посто нных магнитов по предлагаемому ,cnoco6v размагничивание их осуш,ествл етс  в результате действи  значительных коммутационных ампер-витков, возникающих при реверсировании ротора с большой инерционной массой.When permanent magnets are stabilized by the proposed cnoco 6v, their demagnetization is dried up as a result of significant switching ampere turns arising from reversing the rotor with a large inertial mass.

Процесс реверсировани  разбиваетс  на три этапа. Первый этап начинаетс  с момента изменени  пол рности напр жени  на зажимах двигател  и заканчиваетс  в момент, когда ток  кор  равен нулю.The reversal process is divided into three stages. The first stage begins when the polarity of the voltage at the terminals of the motor is changed and ends at the moment when the current of the core is zero.

Направление намагничивающей силы коммутационных токов совпадает- при этом с направлением пол  полюсов и умепьшаетс  по величине к концу этапа до нул .The direction of the magnetizing force of the switching currents coincides with the direction of the pole field and decreases in size by the end of the stage to zero.

Второй этап начинаетс  с момента уменьшени  тока  кор  до нул The second stage starts from the moment the current decreases to zero.

,и заканчиваетс  при уменьшении до нул  скорости вращени  ротора.and ends when the rotor speed is reduced to zero.

При этом ток  кор , изменив направление, сначала возрастает, а затемIn this case, the current cor, changing the direction, first increases and then

плавно убывает. .Ввиду того, что направление вращени   кор  остаетс gradually decreases. Due to the fact that the direction of rotation of the core remains

прежним, а ток измен ет свое направление, намагничивающа  силаthe same, and the current changes its direction, the magnetizing force

.коммутационных токов будет направлена против пол  полюсов..commutation currents will be directed against the floor pole.

Третий этап начинаетс  с момента уменьшени  скорости вращени  вд нул  и заканчиваетс  при достижении новой установившейс  скоро:ти . Направление намагничиваюш,ей силы коммутационных токов на этом этапе совпадает с направлением пол  полюсов.The third stage starts from the moment the rotational speed decreases to zero and ends when a new steady state is reached: ty. The direction is magnetized, its switching current forces at this stage coincide with the direction of the pole field.
