  • @jumondehtweh7324
    @jumondehtweh7324 2 หลายเดือนก่อน

    Is the diode trio's only function to convert AC produced by the alternator to DC then send that DC current through the voltage regulator which, sends that current to the brushes & slip rings on the end of the rotor's shaft; to energize the already spinning rotor making it an electromagnet? I'm confused. Why not go through the rectifier?

    Excellent video but contains a major discrepancy. 0:44 and 1:32 defines an alternator as a device that converts mech energy to "AC" electrical energy. 9:38 defines it as a device that converts mech energy to "DC" electrical energy. Which is it?

    • @ricardogarcia3900
      @ricardogarcia3900 3 ปีที่แล้ว +1

      The formal definition of an alternator is "mechanical to electrical energy". But the case exposed in the video is about the alternator of a vehicle, where it must feed the electrical system in DC.

    • @angelodanielguevarabobadil7185
      @angelodanielguevarabobadil7185 3 ปีที่แล้ว +3

      Good morning John, at the begining of the process, an alternator convert mech energy to AC electrical energy, later the AC electrical energy is converted to DC electrical energy thanks to a rectifier and/or Diode trio. So both definitions are right in the case of vehicules. But I prefere the second one because it is more complete.

    • @samikpal5585
      @samikpal5585 2 ปีที่แล้ว

      Alternators are ac generators, while generators are machines those can convert mechanical energy in electrical energy (ac/dc) by the help of electromagnetic energy conversion.

    • @billyhorton5779
      @billyhorton5779 2 ปีที่แล้ว +2

      Before 1962, automobiles used a "generator" which produced a dc output with a commutator and brushes, much like what is inside a starter motor. These dc generators did not put out much amperage at low speeds. The "alternator" will produce amperage at lower speeds, alternator meaning "alternating current" but which has to be rectified into "direct current" or dc to charge the battery and power everything as explained above. An alternator requires dc to produce Ac, then rectifies it back into dc. Hope this helps

    6:32 I'm confused here! Some please explain this in very simple terms for me?
    "Recall that we have 3 AC voltages being produced in the stator windings, why not use all 3 of these voltages? Infact, the diodes are configured in such a way that we rectify and convert both half circles of every stator voltage AC voltage."

    • @realpars
      @realpars  5 หลายเดือนก่อน

      Hi there. Thanks for your question. Each winding produces an AC voltage because of its physical structure, so the voltages are out of phase. Each phase is connected to a diode pair that provides rectification. Therefore, we end up rectifying each half cycle of each voltage produced. I hope that answers your question.

    It's very detailed but I still have question in mind... Does it mean that without battery the alternator cannot produce electricity because there's no voltage to supplied in rotor to create an electromagnet from the start?
    Or can it still produce electricity? Because there's a generator like (Honda ER2500CX Petrol And Gas Generator) there's no battery in it and just start only pulling the cord
    Thanks by the way your video is very awesome👌hope you could answer my question

    • @realpars
      @realpars  5 หลายเดือนก่อน

      Hi, Thanks for reaching out......Automotive alternators require an initial battery current to create an electromagnet in the rotor. No battery, no electricity, no start. Small portable generators use permanent magnets or other principles to generate electricity without a battery. I hope that helps answer your question.

    I have a problem
    When measuring the voltage on the battery terminals while the engine is running, it gives 14 volts, which means that the generator is working properly??? However, when I disconnect the battery cable, the car stops. What is the reason?

    • @realpars
      @realpars  ปีที่แล้ว +1

      Hi there........ A reading of 14 volts, while the engine is running, is normal and means the alternator is working just fine.
      I’m not sure why you would disconnect the battery while the car is running, but I wouldn’t worry about the engine quitting. The alternator supplies power to the car, but some vehicles do so via the battery. Best to check with the dealership and ask if your car fits into this category. But, if it was me, I wouldn’t worry about it, and I wouldn’t disconnect the battery while the engine is running.

    Why do we call alternator as doubly excited machine. Do we give 2 supplies, one ac to stator and dc to rotor as here rotor is producing voltage in stator.

    • @realpars
      @realpars  3 ปีที่แล้ว

      Hello Sssa. An alternator doesn't really have 2 supplies. There is one DC supply to excite the rotor. There is an AC output created by the spinning rotor interacting with the 3 windings of the stator. That AC voltage is rectified and becomes a pulsating DC voltage.

    • @samikpal5585
      @samikpal5585 2 ปีที่แล้ว

      Doubly excited machine means we give 2 types of input. One is mechanical (rotation/kinetic energy) and second is field excitation (dc electrical energy). Same thing can easily be explained in case of synchronous motors (which is just opposite of alternators) there we give AC input to stator and dc input to rotor and in the expense of these two excitation we get mechanical rotation.
      A singly excited machine is Induction motor. Where we only give one supply that is to the stator (ac supply to create RMF) which alone is enough to produce the rotation of the machine, i.e., mechanical power output.

    • @samikpal5585
      @samikpal5585 2 ปีที่แล้ว

      We obviously give dc to rotor but we don't give AC to stator in case of alternators. Actually we extract ac from stator while giving mechanical rotation to the shaft. What you're saying is exactly the principle of synchronous motor. Both alternator and synchronous motor are doubly excited machines

    • @fajaradi1223
      @fajaradi1223 หลายเดือนก่อน

      The stator was configured in Y pattern. So the stator has 3 output. Then we put 2 diodes for each output, hence the 6 diodes.
      Additional notes. Generator stator's number always a multiple of 3. One end of each coil windings will be tied together, while the other ends untied, and will be used as output.
      If you really wanna know on how a rectifier works, I suggest to build one by yourself. Try a full bridge rectifier. It's commonly used on an audio amplifier/speaker.
