The generation of chord communication electricity
Sine communication is fromExchange generatorsThe generators were generated and usedElectromagnetic inductionThe principle of converting mechanical energy into electrical energy。
In daily production and lifeElectric motorThere are many applications, and many equipment uses electric motors as a power source. The power motive, combined with the power exchange, will function. The common exchange of the arcade motor is made up of rotor circles and rotors, where the exchange power is added to the spinner circles, which generate a rotation magnetic field, which drives the rotor rotation. The generators, on the other hand, are subject to a voltage (i. E., electric motion) sensed in the fixed circuit。
The basic structure and rationale of the communications generators are shown in figures 2-3. The rotor is made of a permagnetic body, and when a water turbine or a steam turbine drives a revolving generator, the rotor's magnetic extreme rotates, it causes the aluminum to circle the radiation magnetic field, the magnetic line to cut the contour group, it creates an induction electric motion in the contour group, and the rotor's magneto-turning group to generate the corresponding electric motion (voltage)。
The polarity of the sensory dynamic also corresponds to the polarity of the sensory magnetic field, as the strength of the sensory motor is proportional to the strength of the sensory magnetic field. The induction magnetic field to which the tpg is exposed is a reverse cyclical change. When the rotor magnetic polar equilibrium moves, the sensor magnetic field changes by the sine pattern, and the electric motion from the generator is the sine wave shape。
Generators are electrodynamically active according to the principle of electromagnetic induction, and when the circuit is affected by a modified magnetic field, the circumcised magnetic line produces an induction magnetic field, which is directed in the opposite direction. A generator's rotor can be considered as a permagnetic object, as shown in figure 2-4 (a), when n is extremely rotated and close to the aphrodisiac circle, it produces an induction magnetic field in the direction of n →s, which produces a sensory electric motion of a progressively enhanced curve, which is gradually reduced when the rotor's extremes continue to rotate。
As the rotor magnetic poles continue to rotate, the rotor magnetic poles s begin to approach the fixed circle, and the magnetic poles of the magnetic field have changed. As shown in figure 2-4 (b), the induction electrodynamic polarity generated by the fixed circuits also flips 180°, with the sensor electric motion output being the curve of reverse change. The rotor rotates for one week, and the sensor electric motion changes again. Since the rotation speed of the rotor is constant and even, the wave shape of the output dynamic is the sine wave。
Single-stage communicationThe creation of
In the generator, the sensory dynamic (voltage) generated by the stationary circuit is also a group, transmitted by two lines, as shown in figures 2-5. This approach is mostly used in small mobile generators。
The generation of two-way communications
There are two sets of fixed circuits inside the generators that are distributed vertically among the rotor periphery, as shown in figures 2-6. The rotation of the rotor results in two sets of sensitisations, with a 90° phase difference between the two sets. This is a two-phase power supply. This is used mostly in automation equipment。
