The most efficient use of language. No "fluff", you presented the information extremely well. Subscribed. I will definitely be watching more of your videos when I have time.

Thank you for a very clear descriptions of various motors. This was a real uplift after my high school level Physics some 30 years ago. You have a very good command of the subject and explain it very well with good diagrams. You sir are a very good teacher. Now i am ready to attack the brushless DC motor in my airconditioner indoor unit. I will be changing the ball bearing in it and won't be shocked any more to see that it does not have the messy carbon brushes that old motors had.

@ThePostApocalypticInventor9 жыл бұрын
Well I sure like to hear that ! I guess I'm not really a typical German. When I meet American tourists at local attractions, museums etc, I often have a little chat with them and we really get along quiet well. Those guys always say something like " Are you sure, you're really a German ?" They always seem to expect a somewhat more "blunt" and less polite behavior, as well as a general negative attitude towards life. And I guess many Germans must seem that way, when you meet them for the first time. Germany doesn't have a culture of "positive thinking", as it may exist in the US and many other countries. Also quiet some people value honesty over politeness. If you ask a typical German "wie geht's dir ?" ( "How are you ?") you will often get an actual negative answer like "well actually not that great...". Then they might even start to list all their issues :D. Most of my friends and relatives are that way. A friend from Scandinavia once told me that she found that very strange. She even disliked me for it when she first met me. It really opened my eyes how many of us must come across.

I have had a phonograph with motor/transformer supplying a 3 transistor amplifier. I now have combination radio/phonograph/tape recorders with a.c. synchronous and capacitor start a.c. motors. Using on different frequency requires exchanging pulleys to compensate for the different rotation speeds on 50 or 60 Hz. All phonograph and tape recorder brushed d.c. motors also incorporate a speed governor consisting of centrifugal switches cutting in resistances to maintain correct rotational speed since BDC motors run at no certain speed. Then I have had many small BDC motors from toys, portable fans, drills etc. I have tested and serviced 3 phase a.c. motor softstarters using thyristors. In all I'm fairly well versed in a.c. and d.c. motors too.

Hello and thank you for all it took to make this video. Just found and subscribed. I played with brushed motors n solar cells, buzzers, step up xformers, speakers etc when I was a kid. Love this stuff. Now being in the RC Airplane hobby, I am getting more interested in wrapping some motors and later making a brushless motor controler. I am very weak on electronic theory but study these things and then do them. Sometime I want to try building a hi efficiency brushless motor for airplanes with a larger diameter so more torque would be achieved with less power or current. Larger dia motors would maybe see better use as pushers because of the drag unless a larger spinner is used for tractor ( pulling ). I have allready seen some of these and they are quite expensive and have very low kv ratings. I would like to find something to wrap a motor with outer can diameter of say 2 - 2.5 inches to spin a 12 x 6 prop at about 10,000 rpms on 11.1 v lipo using a regular motor controler and hope for current of like 5 amps or what ever. A fun project, more efficiency, something hand-made. Put it on back of a Saab J21 or Vampire pusher or forward on P51 Mustang. Any ideas where to look to achieve this without re-inventing the motor or the wheel or reading "War and Peace" to do it. Info like this seems fragmented piecemeal hard to find. Any ideas, anybody else allready doing this? Really like your video and theory explanation, used to work as a tech now a pipefitter but I love this stuff. Thank you.

Hey this is a very good video. I would like to pick your brain about a way to measure the output mechanical power of an motor, as i see you have a very inventive way to see things. Thanks.
@ThePostApocalypticInventor10 жыл бұрын
Stanila Stefan You have to connect the rotor shaft of the motor that you want to test to the rotor shaft of a DC motor and connect an adjustable dummy load to that DC motor. The DC motor will act as a "generator brake". The only thing you have to do then is to measure the voltage across the pins of that DC motor, as well as the current flowing into the dummy load. Then you multiply that voltage with that current and you will get a power value. You then only have to correct the result by multiplying by a correction factor, that compensates for the friction losses. You would then simply vary the supply voltage of the motor under test, as well as the size of the load until you have found the MPP (maximum power point) of that motor. The motor will produce different levels of power depending on its supply voltage and the size of the load.
@stanilastefan168710 жыл бұрын
The Post Apocalyptic Inventor Sorry for misleading you. Is not about dc motors it is about high power 3 phase motors powered at a single phase line. I am trying to find the right capacitance for the maximum mechanical energy output. I am thinking of a jig that can measure that since i can't rely on measuring maximum power consumption due to the breaking effect of to much capacitance.
@ThePostApocalypticInventor10 жыл бұрын
Stanila Stefan I guess you didn't understand what I said. This method can be used to test ALL kinds of motors. the DC motor is not the one to test, but it acts as a GENERATOR that is connected to the motor that must be tested. The DC motor is acting as a generator that generates a dc voltage that is proportional to the mechanical power delivered by your 3-phase induction motor. If I could make a drawing you would understand it, KZfaq comments are not suited to discuss matters like this :D
