How do diesel generators generate electricity?
May 17, 2022
Diesel generator set refers to a mechanical device that converts other forms of energy into electrical energy. It is driven by a diesel engine and converts the energy generated by fuel combustion into mechanical energy and transmits it to a generator, which is then converted into electrical energy. With the development of society, diesel generator sets are widely used in industrial and agricultural production, national defense, science and technology and daily life. So do you know how diesel generator sets generate electricity? In this article, the generator manufacturer JUNVOCH will give you a list.
Generators are usually composed of stators, rotors, end covers and bearings. It works according to the principle of electromagnetic induction. The generator converts mechanical energy into electrical energy through the relative movement of the rotor magnetic field and the stator windings.
When the rotor is driven by an external force, the rotor magnetic field and the stator conductor move relative to each other, that is, the conductor cuts the magnetic field lines, so an induced electromotive force is generated in the conductor, and its direction can be determined according to the right-hand rule. Since the position of the rotor poles causes the conductors to cut the magnetic field lines in a vertical direction, the induced electromotive force in the stator windings is at a maximum at this time. After the poles have turned 90 degrees. The magnetic pole is in a horizontal position, the conductor does not cut the magnetic field lines, and the induced electromotive force is zero. The rotor turns 90 degrees again, and the timing stator winding cuts the magnetic field lines in the vertical direction, so that the induced electromotive force reaches the maximum value, but the direction is opposite to the previous one.
When the rotor turns another 90 degrees, the induced electromotive force becomes zero again. In this way, the rotor rotates once, and the induced electromotive force of the stator winding also changes positively and negatively. If the rotor rotates continuously and uniformly, a periodically changing alternating electromotive force is induced in the stator winding.
