hi, friend like and subscribed I have a question Can it be configured that when the machine is turned on, the motors always go to a specific point even if the machine remains in another position previously turned off? thank you

@stijnsprojects 19 күн бұрын

You can program this in the microcontroller or PLC or ... but not in the motor driver. You can search for the Z pulse and based on that you can move to a certain position, or you can use an limit switch. You can also look for a motor with an absolute encoder so you don't need to search for the Z pulse first but this only works for 1 rotation.

This is exactly the type of tutorial I’ve been looking for, thank you! Is it possible to connect to some sort of code (maybe on raspberry pi or/and arduino) that would allow it to change its strength? For example if used in a robot, could it be possible for an ai program to control the grip strength of individual fingers/ arms? If so- I’m not sure at all how that works actually 😅 I’m building a personal project (it’s honestly a bit of a pipe dream) without any previous knowledge and just using info that’s already available since I’m not trying to go into an advanced career- it’s more of an art project if anything

@stijnsprojects 2 ай бұрын

You can control the force by regulating the air pressure. To regulate the pressure, you can use a microcontroller to control an electro controlled air (pressure) regulator. Good luck with your project.

why do you divide the ascii input code by the encoder cpr? from my understanding if flypt sent 511(middle bit) to your odrive it would go to 511/1600 turns? how to you accomodate the turns to length travled for an actuator? from the scale function? but if thats the case u cant even make a full turn if you at 10 bits and with linear actuators that doesnt make sense.

@stijnsprojects 2 ай бұрын

I did that because when I made mine, the units were different so I wanted to keep it the same. There are multiple ways to achieve the same functionality such as multiplication or division by a factor in firmware, using a microcontroller to change the value, maybe even multiplying or dividing by a factor in flypt. There have been many updates to the firmware and flypt since I made my sim.

I have a two-motor board labeled "odrive v3.6" which connects to this "ODrive Python GUI 051" and I can edit/save some items but the calibration does not make the motor spin. In odrivetool it says I have "Odrive control utility v0.6.9.post0" and ODrive v3.6 with firmware v0.5.1. Tutorials have some lines that don't work for me like selecting gpios for the hall sensor on my hoverboard motor. One answer appears to be to cmd line "odrivetool dfu" to update the firmware, but it seems the "ODrive Python GUI 051" then may not work... Can these clone boards be updated to the newest firmware or should I keep what I have? thanks for proving all the info, its been helpful learning.

It's possible to update a clone board, you can find the information on the ODrive website (docs.odriverobotics.com/v/0.5.4/developer-guide.html). I also have a video on how to upload firmware to the board that can help but the process had changed a bit since then (kzbin.info/www/bejne/jKCXYXapobOsrsk). If I have the time, I will make an up to date video on how to flash the firmware.

@stijnsprojects 4 ай бұрын

The force and stroke of the actuator depend on the dimensions of everything. As seen in the video, the stretching of the sleeve is not so regular when it's to large. Because the parts are cheap, I recommend buying a few sizes and trying some things out. As a reference, I used the same diameter of silicone tube as the coupler was made for (OD 8 mm, ID 5mm) and the sleeve that worked best is a bit smaller, 6 mm.

@@stijnsprojects sorry didn't mean to sound hostile. I like stepper motors because one can run them open loop, but closing the loop makes things run so much more stable. although one still has to remember to set the maksimums, if you don't want to make the motor smoke, was fiksing a 60amp 600v motor drive, and using a 1kw motor which is not a problem as long as the feedback is working, well between test it had reset the current limet, so when it didn't see the motor move it it just just starte turning up the current until the motor moved or something broke, in this case it was a breaker that saved my test motor but a bit of smoke did some from it.

Hi, I'm working on a hand crank (1:9ratio ), axial flux 3 phase alternator, 12 wedge shaped magnets per rotor half. Stator consists of 6 (18 awg) w/ 250 windings ea coil., sandwiched between the two rotor halves, similar to yours. 3 phases w/ bridge rectifier. I'm aiming for 16V DC stepped up/ down with buck/ boost. Plan is to charge 2 parallel rows of (6x) 500 F Super Capicators for16V (max) and a net capacity of 83 F. Incorporated will be L-ion battery bank for ~5V and an 18A AGM for 12V. Additional ports for for alternate DC Voltages/ Amps. Question: Do you feel as though the iron core has a favorable effect on your motor? Is cogging an issue? I have the option of using a ferrite core at each stationary coil, I wonder if it will help get slightly more efficiency using the cores? Thoughts?

you can find special mineral oil to transfer from windings to outer shell, needs a hold for input, just a tiny bit of oil will change the transfer a lot, pro motor thermal oil uses some kind of suspension maybe just fine iron to aid heat transfer, search for grintech cooling oil formula to know more.
