Why induction transformer called rotating transformer?
Transformer has windings
Chorded windings are used in induction motors because?
Its the simplest way to reduce the harmonic induction torque(i.e. by weakening the stator winding mmf harmonics)
When the current flows through the secondary windings it sets up an electromagnetic field.The electromagnetic field then cuts the secondary windings there by producing secondary voltage known as what?
mutual induction
What will happen if you run induction motor beyond its rated speed?
The windings will heat up and evntually be destroyed due to the high rate of speed which induces more ccurrent in the windings
The basis of general theory and generalised equation of ac machines?
The general theory of AC machines is based on the principles of electromagnetism, which link magnetic fields and electric currents. The generalized equation for AC machines typically includes components for the electromagnetic field, stator and rotor windings, and mechanical motion. These equations are used to analyze the performance and behavior of various types of AC machines like induction motors and synchronous generators.
Induction Motor working principle?
An induction motor works on the principle of electromagnetic induction. When an alternating current flows through the stator windings, it creates a rotating magnetic field. This magnetic field induces a current in the rotor windings, causing it to rotate and drive the attached load.
What is the purpose of the primary windings of a transformer?
The primary windings of a transformer are responsible for receiving the input voltage from the power source. When an alternating current flows through these windings, it creates a magnetic field that induces a voltage in the secondary windings through electromagnetic induction. The primary windings essentially convert electrical energy into magnetic energy, which is then transformed back into electrical energy in the secondary windings at a different voltage level.
What happens if the rotor in an induction machine is replaced with an iron cylinder?
Nothing. The motor won't run because you would no longer have the counter-acting magnetic field from the induction windings in the rotor.
What is an Induction Machine?
An asynchronous alternating-current machine, such as an induction motor or induction generator, in which the windings of two electric circuits rotate with respect to each other and power is transferred from one circuit to the other by electromagnetic induction.Reference: Wiki Answers
How are the windings of an induction motor made?
The windings of magnet wire are made on a machine that counts the loops of wire as they are formed into usable coils. Once the coils are complete they are installed into the stator slots in a specific order.
What is the principles of DC machines?
All DC machines are works based on the principle of FARADAY'S LAW OF ELECTROMAGNETIC INDUCTION.
Where are the main windings of an AC induction motor situated?
Front and rear.AnswerThey are located in longitudinal slots that are machined into the inner surface of the stator.
