I "know" how things work, based on principal, but I've always been that guy who had to take it even further and dissect my electronics. Got me into a lot of trouble as a kid, hah. After watching this though I realized that I may be obsessed with motors in general... 🤔

I have worked with installing and repairing AC's/air heat pumps. (Here in Sweden they are mostly used for heating...) It was pretty much always a fan motor, some problem with one of the circuit boards or the valve used to swith between heating and cooling. The circuit boards was just quicker and cheaper to replace the whole board instread of searching for and replacing one component. Anyway, I think I have replaced one of those sweeping stepper motors once, and then we had to send it back to the manufacturer as it was a guarantee job and they needed it for "analysis". Nice to see what's inside one of those, never had the chance to take one apart.

I guess it could if you just left the positive common wire disconnected. It would present a higher winding impedance though. The air conditioning units usually just use the ULN2003 or 2803 or even just discrete transistors. It's a nice simple way to drive a stepper.

Tnis is actually how the steppers in FTIR instruments work. To save cost there is no "zero" indicator. Instead the software moves the motor all the way to the end and then some, letting the motor "slip" . After that time it knows it will be a zero position. From that point it can then count steps to go to a known position

Hi Clive! I really enjoy all of your videos. I've been subscribed for a few months now. You have a fantastic wealth of knowledge. I do have a question about this sample circuit you've made with a PIC 12. I work in IT as a network architect, but I'm totally new to microcontrollers. I've been poking around looking for information on how to get started with a PIC chip. But I wanted to ask if you used a PIC Kit or similar device to program the IC?
@bigclivedotcom9 жыл бұрын
+Peter Trom The easiest way to get started with PICs is to use either a PicKit3 or PicStart plus. Both supplied by the same company that makes the chips and very affordable. Have you considered the Arduino platform? It's even easier to get started with.

+Peter Trom Arduino is the thing for microcontrollers really with loads of tutorials on youtube and is totally open source, meaning you can buy the un-programmed chips and make your own version, if you wish. But as an alternative there are also the PICAXE chips which are programmed with a version of BASIC, however, you have to buy the preprogrammed chips, so is not really open source like the arduino.

I've got a similar looking stepper, but says 6v 10ohms (part number 20BYJ01-160HR).. however the motor drivers I've seen all have a trim pot to adjust the vref until it corresponds to the maximum current you want to drive. But I can't find any datasheet on the motor, so how do you know how much current it can take? Or the number of steps per revolution? And what happens if I apply 8v-24v instead of the 6v?

Hey Big Clive, the only motor I've seen that is close to or pretty much could be identical in some ways of size is the ones used in a microwave oven for the turning plate. They have a geared end on them instead of that flat style like those & turn completely around of coarse but have you ever noticed that when you restart the oven it starts up in the opposite direction? Why do you think that is, or what causes that to reverse itself once stopped like that? Thank you for your time BC, Tom.
@bigclivedotcom6 жыл бұрын
Microwave turntable motors are synchronous motors. They rotate at a speed determined by the mains frequency and the basic units have no particular direction. If you stall them they will just kick off in the opposite direction. To get direction you either need two windings with a phase shift (capacitor) or a mechanical latch that physically stalls the motor if it goes in the wrong direction.
@AThreeDogNight6 жыл бұрын
OK, now that makes sense because at first I was thinking surely they would have a capacitor used for filtering if nothing else, so now I understand without it how it just changes rotation, thank you BC, Tom.

@bigclivedotcom8 жыл бұрын
A wiper motor might not be the best option. Many of the puppet displays use a small mains powered motor with an offset cam that pulls lots of wires attached to it simultaneously. But of you do end up using the wiper motor you can reduce the noise and speed by using a lower voltage to run it.
@ItstoytimeUK8 жыл бұрын

That would be a synchronous motor. Ever wondered why the plate can sometimes turn the opposite way, seemingly at random? Those motors can go in either direction, depending on which winding kicks off first. Some have a capacitor to create a phase shift, which makes it always go in one direction. If you stop the plate from spinning, it will start spinning in the opposite direction.
