Test it without the 2 touching each other and verify with ultra slow motion camera. When it looks perfect, try going in and it would save you a lot of failures although some thing's may still fail in the final testings.
There are a lot of variables that can go wrong. I rebuild electric motors. A perfect looking motor that passed all electrial tests can just pop off. That's always a bad day...
Yup. Once they locked in before the spin and then spin at the same time they will also be synced. It's just a trickery of our minds thinking it will crash at the speed they are going, however they are spinning at the same rate at the same spot.
@@RG912 the tolerance is actually pretty big if you look at the start of the video. Also modern drives are really precise/responsive. An there is not even a load on the motor that helps also. Modern servo drives have a precision of 1048576 increments/turn and a whole lot of torque
this is how formula 1 gearboxes work btw they engage when the gears are perfectly aligned, times in the millisecond range. nice demo to see this live 🎉
when those two parts were meeting in fast spin mode, the rotational direction might be same, may have little speed differences from each other, but if each rotating toward different directions, then the track moving speed was not enough for fast-spinning black and white notches to full enter into others groove and back without knocking onto each other
Yeah as the guy above said, you can machine one side of a component on a lathe, then pass it over to the other side whilst maintaining hole positions, milled profiles etc.
Это было бы круто в 80 десятых Ну щас есть ардуин и частотник и контролер и куча всего . думаю даже я колхозник с чуть пониманием смог бы совместить и ненхрагизовать и вращение и их сцепление .
@@havanasyndrome3024no nails are needed to build a house either.... Not sure what you mean specifically by your comment. Are you trying to suggest that these two specific motors where synchronized without programming them? Or merely stating a random fact? I mean Japanese wood-joining techniques are fairly intriguing to me to be honest. Definitely worth checking out!
@@ZenithWest169 these are stepper motors. So you simply have to wire first one to rotate clockwise and second one counterclockwise, into the same off the shelf stepper motor controller, and voila. You got two perfectly synched motors. Zero programming required. Or you could go the dumb/inefficient/worse working route and create custom controller mirroring the slave motor from the master motor... Brilliant engineering involves simplifying, not complicating things.
That is very simple to make as they get the exakt same signal all the time (although one inverted) . Do that same thing but with different rotation speed on the two servos, then it starts getting tricky to sync at engagement.
Can you help me to understand this . What does this called ? It can only be achieved through CNC controller? Any article or manual shout you suggest to learn this thing ?
If they are stepper motors, they would be getting the exact same signals. Servo motors are a little bit different, relying on an encoder and a drive with a control loop. The precise control of the servo from the drive allows for very coordinated motion, including synchronization from either a master drive or an external motion controller.
