An electric motor uses electrical energy to produce mechanical energy, very typically through the interaction of magnetic fields and current-carrying conductors. The reverse process, producing electrical energy from mechanical energy, is accomplished by an alternator, generator or dynamo. Many types of electric motors can be run as generators, and vice versa.

Basic principle of electric train?
The basic principle of the electric train is quite simple. An electric motor in the locomotive or above each car is charged with electricity propelling the train forward or backward.
What did Michael Faraday make in 1824?
In 1824, Michael Faraday invented the first electric motor. He demonstrated the principle of electromagnetic rotation, which led to the development of the modern electric motor.
Which product was Michael Faraday among the first to build?
Michael Faraday first invented the electric motor.
What is principle of stepper motor?
A stepper motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. It moves one step at a time.
When was the electric motor patent?
The first patent for an electric motor was granted to the American inventor Thomas Davenport in 1837. His design utilized a simple electromagnetic principle to convert electrical energy into mechanical motion. This invention laid the groundwork for future developments in electric motor technology.
Electric cmarator working on the principal of amplifier and digital sigital signals true or false?
The electric motor does not work on the principle of the amplifier and the digital signals.
How does an electric train work and what are the key components involved in its operation?
An electric train works by using electricity to power an electric motor, which then turns the wheels to move the train along the tracks. The key components involved in its operation include the electric motor, power source (such as overhead wires or a third rail), control system, and wheels on the tracks for movement.
The operation of an electric motor depends on?
The operation of an electric motor depends on the interaction of magnetic fields, passing of electric current through coils of wire (armature), and the resulting electromagnetic forces that cause the motor to rotate. The direction of the current and the arrangement of the magnetic fields determine the direction of the rotation, while the flow of current and the strength of the magnetic fields dictate the speed and torque of the motor.
What principle does a operation of digital computer based on?
Counting, using the binary system. Logic 1 and 0 representing electric current on and off.
Why is it important that the current in the coil of a motor changes with every revolution?
The current in the coil of a motor changes with every revolution to ensure continuous rotation and efficient operation. This change in current direction generates a magnetic field that interacts with the motor's permanent magnets or stator, producing torque. If the current did not change, the motor would stall as the magnetic fields would align and no longer produce the necessary rotational force. This principle is fundamental to the operation of electric motors, enabling smooth and sustained motion.
