Thanks a lot, that is so useful...I am wondering how to insert real values for the following parameters; 1-thermal resistance, and 2- friction force as these parameters are related to the motor type. I mean we want to choose a linear motor that has a specific friction force that relates internal properties of motor construction, isn't it? if yes, how may we determine those?
@iman96_fa :Thanks for your interest. For thermal resistance it is best to use the thermal resistance tool that we implemented into the tool earlier this year, the video does not talk about this (because it was made earlier). please visit: www.tecnotion.com/news/new-advanced-tool-is-added-to-calculate-the-thermal-resistance/ Friction force is related to cables that should be dragged along with the motor, or by friction coming from the bearings, et cetera. It is indeed the case that heavier motors typically face higher friction. You do not need to calculate the force the motor has to overcome (e.g. by F=ma) and put it there, that is something that the tool does itself. Please feel free to contact us if you have any further questions. contact email: support@tecnotion.com
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.
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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-G2oyEoTyDHI.html
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.
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.
@@patrickmanser7425 : 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.)
