You all must have this kind of questions in your mind. Below article will solve this puzzle of yours.


In a split phase motor, the running winding should have a high resistance and low inductance b low resistance and high inductance c high resistance as well as high inductance d low resistance as well as low inductiance Ans: b. If the capacitor of a single-phase motor is short-circuited a the motor will not start b the motor will run c the motor will run in reverse direction d the motor will run in the same direction at reduced r. Ans: a. In capacitor start single-phase motors a current in the starting winding leads the voltage b current in the starting winding lags the voltage c current in the starting winding is in phase with voltage in running winding d none of the above Ans: a. In a capacitor start and run motors the function of the running capacitor in series with the auxiliary winding is to a improve power factor b increase overload capacity c reduce fluctuations in torque d to improve torque Ans: a. In a split phase motor a the starting winding is connected through a centrifugal switch b the running winding is connected through a centrifugal switch c both starting and running windings are connected through a centrifugal switch d centrifugal switch is used to control supply voltage Ans: a.

A motor with only armortisseur windings is called an induction motor. An induction motor is the most modest electrical machine from constructional point of view, in the majority of the cases. Induction motor works on the principle of induction where electro-magnetic field is induced into the rotor when rotating magnetic field of stator cuts the stationary rotor. Induction machines are by far the most common type of motor used in industrial, commercial or residential settings. It is a three phase AC motor.

Star Delta Starter – (Y-Δ) Starter Power, Control and Wiring Diagram

An induction motor is an electrical device that converts electrical energy into mechanical energy. It is most widely used for industrial applications due to its self-starting attribute. Slip ring induction motor is one of the types of 3-phase induction motor and is a wound rotor motor type. Because of various advantages like low initial current, high starting torque, and improved power factor, it is used in applications that require high torque, cranes, and elevators. The rotor windings consist of more number of windings, higher induced voltage, and less current compared to the squirrel-cage rotor.

From the left you have the main contactor with the pneumatic timer because your main contactor is always energized, in the Middle you have the Delta contactor with a thermal overload for motor protection in case the motor exceeds the ampere rating set on the thermal overload, on the right you have the Star contactor which is the first contactor to be energized with the main contactor then when the timer reaches its time limit the Star contactor de-energizes and the Delta contactor energizes and the Motor is running at full load. This way, the circuit is completed, as a result;. Related Post:.

Это был шантаж. Все встало на свои места. - Ну конечно, - сказала она, все еще не в силах поверить в произошедшее.

Немало. - В Севилью - по делам? - настаивал Ролдан. Ясно, конечно, что это никакой не полицейский, это Клиент с большой буквы.  - Дайте мне угадать: наш номер вам дал приятель.

 - Танкадо обманул всех. По его тону ей стало ясно, что он все понял. Вся ложь Танкадо о невскрываемом алгоритме… обещание выставить его на аукцион - все это было игрой, мистификацией. Танкадо спровоцировал АНБ на отслеживание его электронной почты, заставил поверить, что у него есть партнер, заставил скачать очень опасный файл. - Линейная мутация… - еле выдавил Стратмор.

Наверху Сьюзан ждала возвращения коммандера, сидя на диване в Третьем узле словно парализованная. Она не могла понять, что задержало его так надолго. У ее ног лежало тело Хейла. Прошло еще несколько минут. Она пыталась не думать о Дэвиде, но безуспешно.

Страна. Однако в списке было еще одно сообщение, которого он пока не видел и которое никогда не смог бы объяснить. Дрожащей рукой он дал команду вывести на экран последнее сообщение. ОБЪЕКТ: ДЭВИД БЕККЕР - ЛИКВИДИРОВАН Коммандер опустил голову.

Смотри. Стратмор пришел вчера с самого утра, и с тех пор его лифт не сдвинулся с места. Не видно, чтобы он пользовался электронной картой у главного входа. Поэтому он определенно. Бринкерхофф с облегчением вздохнул: - Ну, если он здесь, то нет проблем, верно.
