@@jtlee1108 Ok looks like you understand Motors data sheets How can I make a data sheet or who can I hire to create a data sheet from an old existing motor?
Can't believe this gold has been out of my subscriptions list until now. Awesome content, you manage to detail the matter without extending too long the video!
Since you've looked at Faulhaber motors, how much of the FOC/SVM algorithms change if you use one of their linear motors? It would be really cool if you could show the equivalent stator and rotor magnetic fields that you would see inside those motors. Is the rod they use considered a Halbach array? The datasheet sounds like they have sinusoidal back EMF. Sounds like they are a delta configuration, which I think might have some adjustments needed to the amount of voltage applied by SVM compared to Y configurations? I've been having some debates with my coworkers on what the D and Q axes look like in these linear motors. Is it safe to just view this from the electrical phase angle perspective and keep the 90 degree target offset or is there a reason to aim for a different angle (if you're not trying to do field weakening)? As an intermediate question, is there any real difference between a rotary motor with one pole pair versus multiple pole pairs? Does that idea lead right into a linear motor with multiple pole pairs? Any plans to show the steps needed to initialize FOC and establish the encoder orientation? I've seen code that starts a speed control move with open loop and then switch to closed loop. Is that specific to hall sensors or does that apply for encoders, as well? I know that's a lot of questions and it looks like it has been a year since you posted your last video. Hopefully some food for thought if you have any intentions of posting more of these excellent videos.
What does the number of pole pairs mean? I suppose it correspond to the number of windings divided by 3. But at the same time people speak about the number of the rotor poles. Some times we may have 12 windings and 10 poes in rotor. So, how many pairs of poles do we have there? 12/3 = 4 or 10/2 = 5?
Thanks Motors Are cool 👌👍 greetings From Germany 🇩🇪
Great series, I cannot believe how much better of an explanation of FOC this series has been compared to everything else I've seen on the internet.
Aww thanks, this series was largely a result of me trying and often failing to learn FOC from the internet

Absolute piece of art ❤️. Thanks for the efforts

why do these datasheets not list kv or kt values for these motors? arguably, kv and pole pair count are the two most important specs
i also want know
May I ask what does the 'M 1:2' mean, which is in Maxon Datasheet's Electro-Mechanical characteristics?
This is a great play list.
Is it possible to translate it to the other laguages?
Love from India
