Hi Jim, your video series not only teach us about the specific topic of that video, but helps us learn how to look at systems and devices, and think like an electrician or electrical technician in general. I enjoy and appreciate your efforts. Thanks again.
These videos are outstanding. Lots of bad information out there, but this is definitive work - how it should be done the right way. Jim congratulations on your work with NSF and providing an excellent resource for students and teachers alike.
Question: How is it possible to have a solenoid connected to an AC source? Wouldn't that in this case make the brakes vibrate in the frequency of line?
Good question. Yes, AC solenoids are prone to chatter however they also include "shading" coils that decrease the noise and increase holding power that magnetically latch onto the plunger.

Much appreciated! Tell your friends. I've reapplied for another grant with the NSF. Should know if I get it this spring.
This was very informative, thank you very much for explaining this so clearly with visual aids and real applications.
this is more than great
thanks, Jim

Maybe don’t talk to so fast. Bit of a motor mouth with the editing.
