Technical Parameters For Current And Voltage Of Generator

Brush on the brushless DC voltage, with the original motive to drag the armature counterclockwise direction of rotation, on both sides of the coil to cut different polar magnetic field lines, and in which induction generated electromotive force, electromotive force direction in accordance with the right-hand rule to determine. This electromagnetic condition is shown on the diagram.Generator 

Since the armature rotates continuously, it is necessary to alternately cut the magnetic lines of the N-and S-poles by the coil-side AB and CD in the field, although the direction of the inductive electromotive force in each coil edge and the entire coil is alternating. The inductive electromotive force in the coil is a kind of alternating electromotive force, while in the electric brush A, B-side electromotive force is the DC electromotive force (say exactly, is one kind of direction invariable pulse electromotive force).Generator

Because, armature in the rotation process, regardless of the armature to what position, because the commutator with the commutation of the brush, brush A through the commutator of the electromotive force is always cutting the magnetic field lines of the coil edge of the electric potential, so, brush a always have positive.Generator 

The same reason, brush B always has a negative polarity, so the brush end can lead to the direction of the variable but the size of the pulse EMF. If the number of coils per pole is increased, the degree of pulse vibration can be reduced and the DC electromotive force can be obtained. This is the working principle of the DC generator. It also shows that the sub DC generator is essentially an alternator with commutator.Generator

A motor that transforms mechanical energy into electrical energy. Usually driven by a turbine, a turbine, or an internal combustion engine. The generator is divided into two kinds of DC generator and alternator, and the latter can be classified as synchronous generator and asynchronous generator. Generator

Synchronous generators are the most commonly used in modern power plants. It is DC current excitation, not only to provide active power, but also to provide reactive energy to meet the needs of various loads.Generator
