What happens here

One of the individuals delves into the technical specifications of the industrial fan's motor. He explains that the fan can be manufactured up to a 30-foot diameter and attributes its variable speed control to a 30-pole motor design, which eliminates the need for a gearbox. He further elaborates on the motor's internal workings, describing how rows of magnets (poles) interact with the stator and rotor, creating what appears to be smooth rotation but is actually a sequential 'handing off' between magnets. This design allows for precise speed regulation, even though the minimum operational speed might still be around 20 RPM.

Goal: One of the men explains the technical aspects of the fan's motor, specifically discussing its 30-pole design and how it achieves variable speed control without a gearbox.

>> Yeah. That's right. >> So, you said that you make them up to a 30? >> Up to a 30. >> Wow. >> Because of a 30 pole motor and no gearbox, you can slow way down, but you can't go down to just an incremental like >> Gotcha. >> Because the motor has to hand off >> like 30 poles and it can do one pole at a time and I think it's like 20 RP 20 RPM or so. But >> a motor has magnets in it, rows of magnets basically. And as the the center part of the motor which is called the stator, right? Is that the rotor? >> Stater is the part that stays still. >> Stater's on the outside, rotor's on the inside. And there there are windings inside there that touch a magnet. Magnet magnet. Magnet magnet. So as that motor spins, it looks smooth, but it's actually one magnet handing off to the next magnet to the next magnet. Right. >> And we have to get that It's actually kind of complicated to get the initial setup. Yeah. Just perfect. >> I'll bet we get that drone down. And it's getting ready to fly into the uh
