What is the principle of electromechanical energy conversion?

Electromechanical energy conversion is a device that converts electrical energy into mechanical energy or mechanical energy into electrical energy. Electromechanical energy conversion occurs through the medium of magnetic or electric fields, but most practical converters use magnetic fields as the coupling medium between electrical and mechanical systems, because the electrical storage capacity of magnetic fields is much higher than that of electric fields. Electromechanical energy converters refer to gross motion devices such as microphones, speakers, electromagnetic relays, and certain electronic measuring instruments.

DC motors, induction motors and synchronous motors are widely used for electromechanical energy conversion. When electrical energy is converted into mechanical energy, the device is called a motor, and when mechanical energy is converted into electrical energy, the device is called a generator. In these machines, the conversion of energy from electrical to mechanical form or from mechanical to electrical form is caused by the following two electromagnetic phenomena:

1. When a conductor is allowed to When a conductor moves in a magnetic field, a voltage is generated in the conductor.

2. When a current-carrying conductor is placed in a magnetic field, the conductor is subject to mechanical forces.

In the monitoring action, an electric current flows through a conductor placed in a magnetic field. A force is exerted on each conductor. Conductors are placed on the rotor, which is free to move. The electromagnetic torque generated on the rotor is transmitted to the rotor shaft and can be used to drive mechanical loads. As the conductors rotate in the magnetic field, a voltage is induced in each conductor. When producing action, the rotor is driven by the prime mover. A voltage is developed in the rotor conductors. If an electrical load is connected to a winding made of these conductors, current will flow, delivering power to the load. In addition, the current flowing through the conductor interacts with the magnetic field to produce a reaction force that is often opposite to the reaction force produced by the prime mover.

Thanks for the invitation! The principle of electric energy conversion is the left-hand determination and the right-hand rule. The left-hand rule is that a conductor cuts the magnetic field lines to generate current, which is used in the generator principle. Generally, the car starter converts electrical energy into mechanical rotation.

The electric motor is made based on the principle of electromagnetic induction! This principle was discovered by Faraday? It is talking about the principle of the generator. The principle of the electric motor is: the energized conductor (coil) in the magnetic field Medium force movement.

In theory, Oersted was the first to discover it. Oersted discovered that a current-carrying conductor can make a small magnetic needle move. The small magnetic needle is obviously affected by the magnetic force, and the current-carrying conductor surrounds it.

A device or working fluid system modeling that uses electromagnetic theory to realize "conversion of kinetic energy into electrical energy". The generator is one of the indispensable main components.

The laws of electromagnetism can explain

Microphones, speakers, telephone receivers, and telephone microphones are all based on the principle of electromagnetic induction: sound vibrations cause changes in resistance and current, resulting in Change the magnetic field, thereby generating induced current

ElectricityMotivation: An energized coil rotates in a magnetic field due to Ampere's force, and converting electrical energy into mechanical energy is not a phenomenon of electromagnetic induction

Generator: An energized coil rotates in a magnetic field, generating an induced current, and converting mechanical energy into electrical energy is a phenomenon of electromagnetic induction.
