The stated problem of ball screws applies only if you rotate the screw, but you can rotate the nut instead, and thus increase speed and also support multiple carriages.
Very bias. As they haven't talked once about torque of dynamic loads. A linear magnet motor has a spring effect at high loads so not necessarily accurate.
To be clear, the module in motion for the linear motor is required to be powered? If I understand correctly, the cabling has not been shown, for the sake of the animation? Is there a real-world case study available showing the movement, components and cabling? (rather than computer animation)
Yes, the moving part must indeed be controlled. For the clarity of the animation, we left out the cables If you want to see what it looks like in real life, you can check out this video: th-cam.com/video/G2oyEoTyDHI/w-d-xo.html
Main thing that I disagree with is ball screws having "decent" accuracy. In our designs we easily drive those down to micron level. However, I will say I do like linear motors like they show here.
@@patmanlolwut : They also "forgot" to mention that you can eliminate whipping and have multiple carriages with ball screws by rotating the nut instead of the shaft. (As Marcus3d comments above.)

Someone is trying to sell linear motor systems.........

How does the pricing of the linear motor compare to the other three options?
@Tecnotion give price comparison ( base Price x Times) of all 4 motion : when length 1 m , speed 2 m /s ,Load 500Kg
Seems bias

Linear motors will have friction too, and magnets is more expensive than regular metal products

it's on the nose, you can feel it
Bu değerli bilgiler için teşekkürler
So useful! Thanks a zillion!👍
So biased
