Excitation is the device that provides stator power to the generator or synchronous motor stator.
According to the different excitation methods of DC motors, it can be divided into other excitation, parallel excitation, series excitation, compound excitation and other methods. During the rotation of DC motors, excitation is to control the voltage of the stator to change the magnetic field generated and change the speed of DC motors. , changing the excitation also plays a role in changing the speed.
Generator Excitation System Definition
The generator consists of two parts.
(1) Rotor – the rotor winding is connected with direct current to generate the magnetic field of the generator;
(2) Stator – The stator winding is cut by the magnetic force lines of the magnetic field, and a current is generated (sent out) in the stator winding. For an alternator, the generator rotor is dragged and rotated by the prime mover (hydraulic turbine, steam turbine, diesel engine, etc.), so the magnetic field generated by the rotor winding is rotating, and the relative motion of the stationary stator winding cuts the magnetic field lines.
