Description
тей лопаток. Функции покрывающего диска 12 может выполн ть уплотн юш.а диафрагма 13 соответствующего диаметра. Вентил тор обращен лопатками к лобовым част м обмотки 2 статора, так что лопатки наход тс в непосредственной близости от последних .these blades. The function of the covering disk 12 can be sealed by the aperture 13 of the corresponding diameter. The fan is turned by the blades towards the frontal parts of the stator winding 2, so that the blades are in close proximity to the latter.
При отключенном электродвигателе лопатки вентил тора по всей их длине расположены в радиальном направлении.When the motor is off, the fan blades are located in the radial direction along their entire length.
При включении электродвигател в первоначальный момент, пока ротор еще не развернулс , внутренн часть лопаток отклон етс в тангенциальном направлении в сторону вращени под действием вращающегос магнитного пол лобовых частей на магнитные вставки 11. При развернувщемс роторе на отклоненные внутренние части лопаток действует центробежна сила, котора удерживает лопатку в изогнутом положении и регулируетс массой внутренней части лопаток . Магнитные вставки 11 служат одновременно ут желител ми внутренних частей 9.When the electric motor is turned on at the initial moment, while the rotor is not yet developed, the inner part of the blades deviates in the tangential direction in the direction of rotation under the action of the rotating magnetic field of the frontal parts on the magnetic inserts 11. When the rotor is turning, the centrifugal force acts on the deviated internal parts of the blades, which holds the blade is in a bent position and is governed by the mass of the inside of the blades. Magnetic inserts 11 serve simultaneously as sets of internal parts 9.
Лопатки сохран ют изогнутую форму даже при работе электродвигател на неполной нагрузке, когда скольжение незначительно , а следовательно, незначительно и действие магнитного пол на вставки 11.The blades retain a curved shape even when the motor is operating at partial load, when the slip is insignificant, and therefore the effect of the magnetic field on the inserts 11 is also insignificant.
Угол отклонени лопаток определ етс равновесием магнитных и центробежных сил с одной стороны и силы упругости с другой.The deflection angle of the blades is determined by the equilibrium of magnetic and centrifugal forces on the one hand and the elastic force on the other.
При реверсе электродвигател внутренние части лопаток отклон ютс аналогично в противоположную сторону.When the motor reverses, the internal parts of the blades are deflected similarly in the opposite direction.
Таким образом, выполнение лопаток вентил тора с магнитными вставками, расположенными на их внутренней части, и жесткое крепление наружных частей лопаток обеспечивают наличие при любом направлении вращени электродвигател изогнутых радиально оканчивающихс самоустанавливающихс лопаток, что повыщает эффективность охлаждени электродвигател и его надежность.Thus, fan blades with magnetic inserts located on their inner parts and rigid fastening of the external blades ensure the presence of curved radially terminating self-adjusting blades in any direction of rotation of the electric motor, which increases the cooling efficiency of the electric motor and its reliability.
