MAGNETIC LAUNCH SYSTEMS 2: Linear Inductive Motors and how they work

Welcome the Ryan the ride mechanic channel. Im Ryan the ride mechanic
How are you doing today
Im excited to be doing another video in segment all about electric launch rides and how they operate.
So I want to dive right in, today Im going to be talking about linear induction motors and drive, and what makes them tick.
I’ll be coveting some basic theory of operation.
A brief history, some examples, and drive function and theory.
Please excuse the short format, this videos are not met for people with advanced knowledge in inductive motors, this is. For the average person starting with little to no knowledge. The examples I use can be far off of the actual science behind the drive in order to communicate this to everyone.

This is the easiest to understand explanation I've seen for how LIMs work--thank you!

[homeboy_roy]

Always wondered exactly what was producing the sound and how. Thanks for sharing your knowledge

[pnxdome]

Thanks Ryan! Nice explanation! Dont worry about the tele prompter. Its totally appropriate the way you present these topics.

Love the video. Operated Steel Venom (Valleyfair - Intamin Impulse) years ago and it was fun talking to people like this about how it works. Would love to see more details on the control systems for it, and I am sure people would love to know about the light curtains the ride uses in the station area for safety. Keep up the great videos Ryan! Also to note, I have a couple pictures of the cabinets open in the utility building showing some of the switches and PLC if you'd like them. :) I can also talk about operational procedures for them too. Like quick stop recovery and weird things like never E-stopping the ride unless you have everyone off. (Since you need power to release harnesses.)

Thank you SO MUCH for this video. I could write paragraphs about how much this thrilled and educated me. I was 15 in 1997 and would watch my home park (sfstl) test Mr Freeze for at least an hour every visit i made to the park. The first year the ride "opened" it only operated for a short time and had to do extensive testing and power adjustment to fully open a year later and i was just so intrigued at what could be happening inside that shiny station and launch tunnel!

Thank you! I enjoy all the technical things about roller coasters you put out!

[djsinkaz]

Love the longer format and deep dive into the technology. Please do more like this, it may be a niche audience, but at this point it is solely YOUR niche audience. Think you might get into doing one on LSMs?

[gametime]

Awesome explanation. No one is doing what you are with these videos. Keep up the good work, once the coaster community becomes aware of your videos, I think you will get a huge bump. I wish you well. Thanks! I was talking to a Kingda Ka tech on a private tour they did a couple years ago and he said that their system uses the weight of the last train to calculate the force for the next train. He laughed and said you want to get on the next train after a train full of fat people! It's obviously a hydraulic cable launch, not an LIM but I thought that was really interesting. It is mind blowing how much equipment is needed to run that thing. It's a huge building that looks like a power plant.

[AnimationGoneWrong]

I can't imagine the care one has to go through to design and build something like this... 5000 Amps at 1000 Volts is nothing to mess around with! I would NOT want to short THAT out! Great video, Ryan. Thank you!

[SvenDonut]

This really hits the right buttons with me. As an engineer I was always most interested in Electronics. Love the video, was kinda bummed it was over that fast.

[DrHandleMedia]

You know you are a huge nerd when you can pick up insight into why LIM's produce particular sounds at different points of operation like launching and braking. Love the inclusion of more coaster footage being able to hear the sound for ourselves. Keep up the great work!

[probxtion]

man i know nothing about electricity yet i still find this very interesting. Thank you.

[dindog]

this stuff isn't boring. I am geeking out on it. lol

[masonfeagan]

I’ve tried to learn about LIM/LSM motors on my own but there is only so much I can comprehend on my own without someone explaining it—thank you so much!!! It especially helps when you have the visuals up as you explain the concept; that’s just good teaching right there! Well done 👏 👏 👏

[ArtBarn]

Thanks for going into how that drive circuit distributes power, it’s cool that it’s a common power supply and the motors just switch in and out as the train comes to that motor segment.

[engi]

I love this video, this is such a great explanation of something I've been interesting in for a while. Thanks for making such amazing and informative videos!

[Jingles]

Great video! It wasn't too long for me!

[SkeledroMan]

Apparently lightning rod at dollywood had issues with the gap between the LSMs and the train fins. Because the track and supports were made of a lot of wood, they would warp and move too much for the fin to stay within the tolerances.

[Jeff-pbyt]

Dude. I couldn't not subscribe after the way you described how linear induction works. That will forever change the way I think when I get on a roller coaster loll

[danamarie]

Hey I really enjoy your videos, learning about how rides/coasters operate. Could you make a video about how coasters are winterized? Thanks for the great content!
