Great explanation

[@davejohnsonnola2758]

A lot of big stuff around my facility that I don't have to touch but have always been curious about.

[@Straycurrent]

A clear and concise explanation with great diagrams. Thanks, I needed that!

[@HVACS]

Glad it was helpful!

Thank you so much for this great illustration

Learned all of this years ago when learning industrial electronics in college but realized I’ve forgotten lots even bits of it helps greatly doing commercial hvacr. Great descriptions and wiring diagrams!! I retain knowledge much better by seeing than hearing.

Glad I could help!

Thats funny you put out this video. Just ran into a similar situation on Friday. Blower was bad. Customer needed the system back up and running quickly. OEM motor was 2 weeks out. I found a motor at a local electric shop. It was virtually the same 1750 rpm vs 1725. 3 hp vs 2.9. 8.9 amps vs 8.6. It was a duel voltage motor. It is easy to swap the leads around to change it up. Installed it and checked amp draw. I was at 6.9 amps. Customer was happy to have their only system back up and running. He even signed up for our maintenance program
