Thanks for sharing your knowledge
Thanks!
A video on using an autotransformer for load balancing a small generator (5kVa) for maximum efficiency would be cool. 240V in with split phase 120V out and using the autotransformer to create the neutral.
What AC power supply do you recommend for a novice, learning the basics?
Doorbell transformer
@ZackHartle so I can clip this to the windings, and then check deflection?
@@ZackHartle I have a 440 3 phase lathe I'm installing, but the motor leads aren't marked. I need to install a VFD and need the motor at 220v 3 phase.
I'm just a machinist, but your video has helped me establish that it is a WYE motor, but the 6v battery isn't giving enough deflection for my cheap meter to register. So I wanted AC source like you used, so I can use my digital meter. Thanks@ZackHartle

Nice ji

Amazing Zack. Thx.
most of the time it is B phase that is the high leg.
Simple n clear
How are you writing backwards on the screen?
Is this possible on a monophasic motor ?
The way I write on through the glass is really impressive and the lecture is very informative .thanks a lot buddy
Great video! What are you thought about simultaneously supplying multiple loads with a three phase autotransformer? Configuration is 460V source/input supplying one 208V load/output and one 575V load/output simultaneously.
Incredible! Thank you for giving me a way to identify leads when the markings are missing
Wow! great explanation..thanks
Amazing teacher. Thank you.
What does this do to the voltage drop across each leg?
Look I know this sounds immature, but after a few videos, you people could have just said, the starting phase is -30/30 degrees or a 60-degree difference. It is worse than looking up marketing statistics where you just cut the unnecessary paragraphs. But here you got the named laws that you have to pause the video and decipher and learn its not even relevant, unimportant facts which I presume is how to explain it on a test at school because if you are looking for the difference of two transformer configurations, I think you should know how current flow. That's like the first chapter of any electricity book. And there isn't of much of an explanation why unless I missed it because I tried skipping through the caff or looked up the wrong doctrine.
So a shading coil can still be faulty even if it's not broken when you look at it? Chattering can be fixed by changing the coil even if it's not physically broken?
Thankyou 😊
Please can make a video about potential difference and effect on a circuit..
I'm thoroughly surprised to see only 12 comments on this 3 year old video! Where the hell are all the inquisitive minds out there? For the electronics student this video should "Induce" many questions and comments like the one KAFKUBA posted. Student Question Example: Hey Teach we learned what constitutes a "Circuit" but I don't see one here. Please explain how the aluminum can suspended on a steel rod constitutes a 'circuit"? Wakodahatchee Chris
You done it again
Ok so why is not this more common?? I have a transformer which has winding 210=> 0-12-24 So 210input 222 output And 234input and 222output ...
Great video , can you utilize a 3 phase wye generator 120/240 volt for backup power in the event of an emergency on a 3 phase 4 wire delta high leg ? Please explain anybody
Trying to help myself visualize a newton in relation to torque. This wasn't what I was looking for but there was still some information I didn't even know and I use torque wrenches every day. Thank you.
Excellent presentation. I have a variable autotransformer, cheap Chinese "Variac" but Variac is a brand. Thinking about the common leg currents is important not to exceed the current rating of the windings.
Helped me a lot, the only thing I don't understand here is conversion of a mutual transformer to an auto transformer. Do you mean an 1:1 isolation transformer? Since using any standard step down transformer may mean that the primary and secondary may have different current ratings, not only that, the reduced secondary voltage common on most transformers may only allow for a small change in the auto transformers voltage. did you mean a 1:1 transformer. I'm new to all this, could you please explain. Also, how could I tap of midway on the secondary side?
Hi Zac, i need help how did you get the Vtotal? please i tried doing pythagoras like you said but i didnt get the value
This is a very good video. explained very well. I have the same machine , I finished fixing. I had to buy a expensive multimeter because all the multimeters I have couldn't measure capacitors.. But I learned with this video witch multimeter I had to buy... You saved me hundreds of dollars..
V leads by 30 deg..........A lags by 30 deg. are they the same ?
Please help me understand better. with bldc motor I read it on internet Wye 1.7X less KV as Delta. Delta 1.7X higher top-speed than wye, more current than WYE at all RPMs. I assum delta config draws 3A, and Wye also draws 3A, then will Wye give higher Rpm than Delta? Or both configurations have the same rpm, which one will draw more amps?
Thank yu so much ..l am watching from Zimbabwe
What if the Main inputs power supply or Main is 600 Volts Tap accidentally to 480 Volts Transformer Primary windings. What will be the Voltage and Current of a Particular 230/240Volts rated Secondary transformer. What woul be the results.
Nice work. Straight to the point, this is the exact same as the NEC except we switched to 125% of continuous loads vs the .8
It would be good to mention how the magnetic fields for the shaded and non-shaded pole portions do not occur at the same physical location and the armature is attracted to the core irrespective of the direction of the magnetic flux. It is the attractive forces on the armature that add. Explaining WHY the magnetic flux at the shaded pole lags the flux at the non-shaded pole by 90° (induced current in the shorting ring producing its own magnetic flux) would also be helpful.
Cool dea!; Thanks 👍 for that explanation
I love it. Thanks for making my life easier to calculate
Zack, I'm a Chartered Electrical Engineer and Technical Director for my company providing HV designs up to 132kV in the UK. I also provide training. Can I just say that your video is excellent. I was going to produce my own you tube presentation on this for internal training but I think I will just refer people to yours. No wasted words, no BS, no patronising explanations. 10/10. well done. I'll look at your other videos.
Thanks so much for watching!
