⚠ I've made some tests on how to control high voltage frequency, a VFD. The main circuit for a full variable driver is quite dangerous and had problems. That's why I'll make more tests and post a new video on the topic. For now, I hope you will learn new things.

Electronoob love your channel! one thing that this video really has me thinking is safety! I work with high voltage every day. and every time I have to reach in an electrical enclosure I have a deep respect for what is in there. I try to be as safe as possible but there can be a mistake at any minute and it can cost you your life even at lower voltages like your using. I don't want to go on about this for long so I'll make a short list of my concerns. *Latex gloves - won't do much for you, try the real electrical insulated ones made for that. *Saftey glasses - maybe show that you used them? better yet a face shield. especially because of the capacitors. *Master disconnect - even if its a power strip with a switch. what if your motor knocks your board in your lap. sorry, you did have a switch but that will be moving with the cable if it is falling. I don't know how far to take the safety but I would take it a little further just because you probably have some kids and really inexperienced people watching that could get hurt. even if you said not to try this at home. maybe a little more safety? Please? I am one for doing more projects with the higher voltages, but safely.

Great project, thanks for sharing. For information, idealy for an AC motor one should keep the V/f ratio constant. In other words if the frequence is lower that the nominal frequence, the rms voltage to the motor should be lower thant the nominal voltage. On the other side, if the frequency to the motor is higner than the normal frequence, one should boost the voltage, otherwise you quickly loose torque (in a factor of the missing voltage squared).

Heh, I was considering making a DIY 3-phase style VFD. Normal industrial VFDs can only go up to 400Hz, but I am needing one that can do 1.2kHz (for a 72000* RPM motor). Fortunately, I was able to find the correct application specific VFD for pretty cheap. Would still be a fun project though as I am the VFD guy at work would like to get a better understanding of how they work internally. *Edit: I intended to say 72,000 RPM instead of 7200. Its the drive motor for a turbomolecular vacuum pump.

5:28 In three-phase AC motors, the coils aren't necessarily 120° displaced in space. That would be true if there was only one coil for each phase. 5:49 That is Faraday's law (electromagnetic induction). Lorentz law is related to electromagnetic forces, which is what you explained a few seconds later.

Hi, great project. At 8:30 you say you have fullwave rectification, your protoboard layout shows this as well, however the scope trace shows halfwave rectification. I know for the scope trace you have just got a bridge and scope connected in the foreground. I realise you can't connect both channels with common gnds to input and output of a rectifier circuit, so it may have been better to do it in two shots, explaining the outcome.

Yes that's due to only connecting only one probe from the oscillsocope. it was full bridge.
