I´ve been working with German people since I leave the University and I really appreciate them. I have learned lots of things from them. Thank you so much! Your videos are so helpful to me.
By far the best video I've seen on stepper motors. I've used them for projects for 4 or 5 years, but never found a good enough explanation for how they work and why you use an H bridge. Thank you.
@@HomoFaciens I love it, thank you Norbert or whoever read it! It is the best explanations of all the videos I watched. In the youtube, description will be nice to have the advantages and disadvantages of each configuration.
I enjoyed your stepper motor video. The graphics are very helpful for me and I appreciate the way you explain the information. I can;t say I understand all of the information you presented but it is a "step" in the right direction. I will watch this video again and will be looking forward to your future video about controlling these stepper motors. Thank you very much! Harvey from Nebraska
binks166 If you did not know much about stepper motors before, you will indeed have to watch it more than once to get it all. You can also read about stepper motors on my project page: www.homofaciens.de/technics-electric-motors-stepper-motor_en_navion.htm You're welcome! Norbert from Germany.
+Paweł Audionysos Well, I'd like to give a feedback that I have received a compliment and it's part of my educational background in my childhood that I simply can't ignore ;) ...nonetheless I still have some time for creating new things. After the theory about stepper motors there will be a video showing an implementation of those precise drives. Today I have soldered four 4988 stepper motor drivers to upgrade my CNC v2.0 - stay tuned!
From my point of view, such high quality materials are so rare that you just can't simply give a like and sub and move forward. I've literally stopped for few minutes to figure out how i can thank you for all the effort put in to this - it's hard because all positive words were already used in previous comments. I can imagine how much time you spend on this (and recording in two languages) just to share your knowledge for free. I know it's fun to you to but it's you who is learning us and we should thank you. I hope you the best!
+Paweł Audionysos In the near future (2-3 weeks, maybe more) I am planning to start a crowdfunding campaign for my project. Besides money, I will ask for some more ways to support what I am doing (and planning to do). Stay tuned!
thanks for your video; very clear explanation; look forward to your video on stepper motor control (I hope you cover diy circuits and not only ic drivers)
Good explanation overall. The one thing that struck me is that I thought one should apply the right hand rule to determine the magnetic pole when current flows through a coil. The author applies the left hand rule.
As explained in the video, the left hand rule is true when considering the flow of negative charges (elctrons). Considering the conventional current (flow of positive charges) you must use your right hand. In the video I am using red balls to illustrate conventional current (flowing from positive to negative) and blue balls to illustrate what it looks like when considering the flow of electrons (from negative to positive).
No Weißbier! In Hessen we drink Äbbelwoi (cider). You can get a build instruction for my latest CNC on my pages: homofaciens.de/technics-machines-cnc-v3-2_en.htm Don't build and drink ;-)
For unipolar motors araging the steps in the order 1,2,3,4 would have been far easier to follow. Like this it just makes it look more complicated. Check the datasheet of KH42JM2. it shows the steps very clear and nice.
Well, three phases are the simplest type of unipolar motors and it's similar to brushless motors. That's why I have chosen this type. I keep your idea in mind.
Thank you Norbert, for creating and uploading this superb video. May I ask what software was used for creating the animations? Thanks in advance if you get time to answer.
Great explanation but I have a question: I got 3 Pittman 19V stepper motors that have several cables in 3 groups. The group that has 3 (not 4 or 5) all resist movement of rotor if connected by pairs or all 3. I want to use arduino to control them. Can you please tell me how can connect them?
+Alex Echeverría I guess this isn't a "normal" stepper motor, but a DC motor with an encoder. Try to find a datasheet for this type of motor. Have a look at the working principle of closed loop DC motors: ua-cam.com/video/XIUrnR8bLAI/v-deo.html
You are wright HomoFaciens! At the back of the motor there is a device to count rotation and in the iddle of motor I cannot see what 5 cables are for. I am building a CNC cutter and have real nema17 stepper motors for it. I will use this one for something else as I am not familiar with a way to control it using arduino and Easydrivers. Have to read and look lots of your great videos. Thank you for answering my question.
Shouldn't the solenoid poles be inverted with the current flowing in that directions? I mean that north and south of the stator polar expansions should be "coloured" (red and green) in the opposite way to match the field generated by that animated current. Unless the blue dots running into wires are electrons.
+Mario Ursino What time index are you talking of? Note that I am using flowing electrons in the animations, not flowing "positrons" as with the definition of conventional current. Use your LEFT hand to find magnetic north of the solenoids.
Alright then! Maybe you said that in the first part of the video because i jumped to the hybrid motor immediately. You can delete the comment :) thank you for the answer
+Mario Ursino No problem! I like comments that demonstrate real interest in what I am doing in my videos. Yes, I mentioned that I am using flowing electrons at the beginning of the video. If you don't mind I'll keep that comment, because somebody else might also stumble over that issue.
+DEEPAK Dariya That's a really interesting subject for a video, but there are many other projects waiting to become something real. You must be veeery patient...
I hv to submit a seminar report on technical advancements in high resolution motors......what can I cover under this topic...is there any new technology or scope for same in future that I can write about...
+DEEPAK Dariya Yes, steppers with magnetic discs could be a step forward if they become mainstream. Another thing are high resolution encoders for closed loop stepper motors (servo motors), thus improved software and electronics will be an issue.
so what should I include in my slideshow.....I made it all about steppers....and seminar is tomorrow.....as such it is too late.....thanks for replying..my project is in December which is speed control of motor using RF remote.....if u could make a video on that.
+Town Golden If you have listened to my video comments, you should know that there are magnets at the rotors of some stepper motors in this video. The exception from that rule are the the reluctance motors which have an iron core without magnets.
The right hand rule belongs to the movement of positive charge carriers. When I am talking about electron movement (=negative charge carriers) you must use your left hand to find the north pole.
i am confused with the direction of current ,because in each turtorials they use the different of current direction .i wonder between electron direction an conventional current direction which one is right ?
"Right" are bothways of treating current as I am demonstrating in this video! When talking about the direction of current, you must also say what current you are talking of. The action of a conventional current (hypothetical flow of positive charge carriers) flowing from right to left is identical to that of electrons (negative charge carriers) flowing from left to right. Its simple like that.
Thank you. Can you share what you used to animate this video? I am trying to get started making my own videos. Any advice or input is greatly appreciated.
Gary Arthurs The only way of becoming an expert is starting to learn coding - that's never a waste of time. I am coding for years and it's more easy for me to create objects as parameters than "painting" them with a mouse. ..but yes, if you need quick results, there might be better ways.

Mission acomplished!
by far the best tutorial on youtube on the subject
No better person to explain the functionality of stepper motors than the terminator.Great job!

Isn't the reluctance stepper motor basically a 3 phase induction motor?
+awes0meguy13 An induction motor induces a magnetic field in the rotor to get a higher torque, thus that kind of motor won't be a good stepper motor.
