Who started the rotating field system?
The rotating field system was developed by Nikola Tesla in the late 19th century. He introduced this concept as part of his work on alternating current (AC) electrical systems, which allowed for the efficient generation and transmission of electricity. Tesla's invention of the rotating magnetic field was fundamental in the design of AC motors and generators, revolutionizing the electrical industry.
What is the advantage of having a rotating magnetic field alternator?
Advantages of Rotating Field with Stationary Armature1. Rotating field is comparatively light and can run with high speed.2. High voltage can be generate due to high speed and there is very little difficulty in providing high voltage on a stationary part than a moving part.3. It is easier to insulate armature coils for high pressure usually generated (6.6 to 11 kV). Since the stator is outside the rotor, so more space is available for greater insulation required for armature winding.4. Very little difficulty is experience in supplying the field magnet current as it is very low in comparison with the armature current
Could you make a generator by mounting permanent magnets on a rotating shaft and keeping the coil stationary?
Yes, only relative motion between the coil and the magnetic field is important.
Will a generator work if the wire is not spinning but the magnet is?
Yes. One winding/magnet must spin. Some generators have two windings, one is stationary (the stator), and the other spins (the rotor). One of these windings is energized, making it an electromagnet (called the field winding). In most generators of this type, the field winding is the one that is spinning. This is due to the fact that the stationary winding is the actual output of the generator, thus experiences high currents - and it is easier to pass these high currents through stationary busbars to the grid as opposed to rotating equipment.
What does a Rotating magnetic field do?
The Field which is continuously rotating with a particular axis is known as rotating magnetic field. It will be created in Three phase induction motor's stator. When the supply is given to stator of three induction motor, the flux of each phases (that are displaced by 120 degrees) will interact. Due to this the resultant Field will be rotating Magnetic Field will be Produced.
Name the types of alternators based on their rotor construction?
1) Rotating armature alternator, rotates in stationary magnetic field. 2) Rotating field alternator, the magnetic field is rotating.
What are stationary part of dc motor?
The stationary part of any motor or generator is termed the 'stator', and the rotating part is termed the 'rotor'.The stator comprises the main frame (chassis), the magnetic circuit, and field windings.
What are the parts of an alternator?
In an alternator, there are two main parts, one is stationary part and other is rotating part. Field winding may be placed on fixed part(stator) as in case of DC generator and on rotating part(rotor) as in case of AC genarators. Armature winding may be placed on rotating part(rotor) in case of DC generator and on stationary part (stator) in case of AC generator. In AC generators, for all practical purposes you have rotating filed system.
Why is current in field winding of rotating electrical machines always dc?
Because with DC stationary field w.r.t. rotor can be easily created,and permanent pole can be created.
What is field coils?
field coils generally refer to the electromagnetic coils on the stator ( the stationary part of an electric motor ). these generate the magnetic field(s) necessary to put the rotor ( the rotating part of the motor ) into motion.
What are four things Nikola Tesla Invented?
Here is one: In 1882, Serbian inventor Nikola Tesla identified the rotating magnetic induction field principle used in alternators and pioneered the use of this rotating and inducting electromagnetic field force to generate torque in rotating machines. An AC motor is an electric motor that is driven by an alternating current. It consists of two basic parts, an outside stationary stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft that is given a torque by the rotating field.
Which device contains coils of wire that are stationary and rotating magnets that are rotated by turbines?
The device you are referring to is a generator. In a generator, stationary coils of wire are situated within a rotating magnetic field created by magnets, which are often attached to turbines. As the turbines spin, they cause the magnets to rotate, inducing an electrical current in the stationary coils through electromagnetic induction. This process converts mechanical energy into electrical energy.
Does a stationary electron have a magnetic field?
Yes, a stationary electron does have a magnetic field.
What is the name of the iron magnets in the field circuit of a motor?
The stator is the stationary part of a rotor system.

Who invented the Rotating field system?
I don't think anyone invented it, but the one who started it was Lord John Townsend from Brittan.
