ERROR at 15:09 and redrawn at 21:09. Note the control transformer must be connected upstream of the magnetic M contactor not downstream of it as indicated in the diagram. Thanks to John Stillman for pointing this out.

Jim Pytel I was watching this and I was thinking, wtf? Am I missing something? The contact has to close for the control circuit to get power, but the control circuit has to get power for the contactor to close.

Prof Pytel, I like to watch your videos when I'm feeding my infant son. I appreciate your clear and often humorous explainations and examples; in fact, It's often a struggle too contain my laughter and thus avoid startling my son when you use hyperbolic examples to illustrate some phenomenon. Thanks for putting this together and sharing them with the world.

I have been working in the aerospace industry & I don't understand why they don't use the ladder diagram schematic for flight controls, they use something called "Lamm" diagrams which are a hybrid pictorial/electronic symboligy. Ladder diagrams would make sense for hydraulics used in flight controls.

Superb lecture I never ever heard before. Sir can you explain how do operater operate the throttle and speed engine or pilot put on switch and aircraft win flap. How they operate electrically hydraulic or pneumatic system. Please help us to understand this. Thanks.

You have done a lot of intros! Now we need to do some more complicated motor control circuits and a dive into automating a VFD via digital io . Do you have anything on sink and source pnp and npn..... I can always figure out how to get the switch working when they send me the wrong one but I don’t completely understand. Most prox switches now are two wire but I still see a lot of photo eyes that come in 3 and 4 wire configuration.

Stay in touch because I do plan on picking up where I left off once I finish fixing up the basic electricity and electronics series. I do have some lectures showing how to configure digital inputs and outputs for motor drives in the motor drives playlist at: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-uT3m-o1PM3c.html

Thanks again Jim. Enjoy your break. I see you're closing in on 500 subscribers. By the way, those little dots that appear and disappear , usually in the lower right of your graph, are they random or are you sending some secret message?
@bigbadtech
@bigbadtech 9 лет назад
John C Most definitely secret code ... actually it's an annoying "feature" in MS OneNote that leaves the pen cursor in the last place you touched the screen. Yes, super psyched to see the subscriber count hit another notable benchmark. I'm actually doing a presentation at the American Society of Engineering Educators (ASEE) and Hi-TEC this summer and hoping to spread the word. So far the data I've obtained on a small sampling of students (26) present this as a workable and desired option for those enrolled in electronics or renewable energy technician programs. My goal is to keep adding more goodies to the toolbox!

Great, but I think the hydraulic system analogy confused me. I feel that by sticking to electricity alone it would be much more clear. But as I said loved the video thank you very much.

Seems like transistors have been able to do the control function since the 50s or 60s. Controlling a large amount of current with a small amount of current, and isolated from the power circuit. The mechanical approach with solenoids seems like the best you could do before semiconductors, but obviously they are still around. I’m just a hobbyist with some background in using transistors but now starting a class in motor controls. The contactors seem big and bulky for what they do.
@bigbadtech
@bigbadtech 3 года назад
True dat. Modern power electronics devices are much smaller, lighter, and offer additional functionality (example: zero crossing switching) unavailable with traditional electro-mechanical devices like contactors. A lot of the times it simply comes down to price!

Greetings Mr. Pytel, First and for most, I would like to express my gratitude to your kind and humble effort to sharing your knowledge and expertise. In this footage at the time frame 16:03 you indicate a control transformed driving a 3phase motor. The schematic drawing indicates that two of the 3 phases of the line-to-line voltage is being utilized as input to the primary coil of the control transformer. My question is shouldn't all the three phase line-to-line phases be used via contractor. Doesn't 3phase require all the three phase line-to-line phases via contractor ? Your prompt feedback is well appreciated.
@bigbadtech
@bigbadtech 7 лет назад
There is a note in the information section, comment, and floating annotation at 15:09 that indicate the control transformer needs to be upstream of the contactor. The control transformer provides control or pilot level voltage only for the ladder logic circuit and is derived from 2 phases of the incoming 3 phase AC indicated by the colored L1, L2, and L3 connections.
