Description

Предметом изобретени   вл етс  устройство дл  регулировани  скорости асинхронного двигател  при иомощи дросселей, включенных в цеиь статора и подмагннчиваемых в зависимости от скорости двигател , с целью получени  устойчивой работы последнего при глубоком регулировании .The subject of the invention is a device for adjusting the speed of an induction motor with the help of chokes included in the stator circuit and adjustable depending on the motor speed in order to obtain a stable operation of the latter with deep regulation.

Отличительной особенностью предлагаемого устройства  вл етс  применение вибрационного регул тора напр жени , контакты которого включены в цепь обмотки подмагничивани  дроссел . Катушка регул тора включаетс  либо на тахометрический датчик на валу двигател , либо на кольца ротора двигател .A distinctive feature of the proposed device is the use of a vibration voltage regulator, the contacts of which are included in the bias circuit of the throttle bias. The regulator coil is connected either to a tachometer sensor on the engine shaft, or to the rotor rings of the engine.

На чертеже показана принципиальна  схема включени  асинхронного двигател , дросселей и вибрационного регул тора напр жени .The drawing shows a schematic diagram of the activation of an asynchronous motor, chokes and a vibration voltage regulator.

Последовательно с обмоткой статора двигател  / включен дроссель 2, подмагничиваемый посто нным током. Напр жение сети частично компенсируетс  падением напр же1И1Я на лтросселе.In series with the stator winding of the motor / inductor 2 is turned on, which is magnetised by direct current. The network voltage is partially compensated for by the drop in voltage across the choke.

Так как момент асинхронного двигател  пропорционален к.8адрату напр жени , то уменьшение напр жени  на зажимах двигател  в триSince the moment of the asynchronous motor is proportional to the 8-voltage voltage, the decrease in voltage at the engine terminals is three

раза приводит к уменьшению момента в дев ть раз, что практически равносильно выключению двигател .times leads to a reduction in torque by nine times, which is almost equivalent to turning off the engine.

Подмагничивание дроссел  2 импульсами осуществл етс  вибрационным регул тором 3 напр жени , приключенным зажимами а и б к одноименным зажимам тахометрического датчика 4 или к кольцам ротора. Длительность подмагппченного состо ни  дроссел  и соотношение времени подмагниченного и размагниченного состо ни  дроссел  автоматически устанавливаетс  регул тором таким образом, что скорость врашеии  двигател  будет равна заданной величине, т. е. такой величине, при которой напр жение тахометрического датчика 4 равно напр жению «уставки регул тора .The magnetisation of the throttles by 2 pulses is carried out by the vibration regulator 3, the voltage clamps a and b to the clamps of the tachometer sensor 4 of the same name or to the rotor rings. The duration of the choked state of the throttles and the ratio of the time of the magnetized and demagnetized state of the throttles is automatically set by the controller so that the speed of the engine is equal to a predetermined value, i.e., such that the voltage of the tachometer sensor 4 is equal to the voltage of the regulator setting Torah.

Таким образом, момент двигател  измен етс  периодически от значений jVf m.ix Д5 Л1 mill без разрыва тока в силовой цепи. Разрыв тока в цепи подмагничивани  происходит при мощности в 50-100 раз лгеньше мощности силовой цепи.Thus, the motor torque varies periodically from the values of jVf m.ix D5 L1 mill without breaking the current in the power circuit. The breaking of the current in the bias circuit occurs at a power of 50-100 times less than the power of the power circuit.
