@Thepowerof2190 The motor uses magnetic fields to spin the motor, and they are so powerful that they move the camera's sensor. (I think; I'm not a scientist.)
Some.of them do, seriously. (Although appearance is eh, check out the newer electric supercars, the oscilations cause this weird resonance and it's sick!)
We had an 800 hp motor on a hardwood chipper at a saw mill. It ran on 4160 volts 3 phase. It would dim the lights in the whole neighborhood when it started. Back then, there were no soft starters. It was Y start, delta run.
We have 630kW motors near smoking cabin. So funny when it starts with loud explosion sound and someone smoking there. Some jumps, some grab their chests but everyone swears like it their last time.
I'm working on a LOGO project that involves some animation. For the animation I was thinking of using the the sound of an large industrial electric motor and feel like the videos you captured are excellent. Would you consider letting me use the audio tracks for my project?
Is this achieved with high-power semiconductor switches? Does current continue to flow through them during normal running? In that condition, how much power do they dissipate?
As far as i know, they use a big ahh triac to modulate the phase. It probably has some massive cooling for it as it probably dissapates like over 100 watts. I am just assunimg tho based on the sound of it.
