Have you considered using a pair of relays and a timer? I've used two 5 pin relays to reverse the direction of current successfully and i reckon it wouldn't be difficult to use some sort of timer to switch the relays.
It occurs to me the alien could be from one of the universes that has already faded. . Knowing it's inevitable the same will happen in this universe unless the artifact can be used to somehow keep this universe attached to the wave? Coffee fueled btw
Well i just went by the info on the ad itself. I added a cooling fan to be safe and crossed my fingers! I got lucky with the 4 motors seeming to cancel each others electrical noise! I put the car on crates and when I put load on two wheels the other two just slowed to match and there was barely...
These are pics of the sort of motors and reduction gears I'm using
I have removed the inductors and capacitors from the ones I installed, and now I am realising what they do! What sort of things should I consider using caps and inductors?
so you can see what I have done with the relays here is a circuit diagram I did crudely with Paint.
This part at least works perfectly, just the pot wasn't useful to vary the supply.
The PWM module claims 480W at 12V, I expect to peak around 300 or so.
My existing relays are wired to deliver a variable input in forward or reverse. I tried using a pot to vary the power but i had no start up power except on full. I think this unit will deliver variable speed to the motors.
After a bit more reading after your advice I've come across this:
As far as I understand, I could use this in conjunction with...
I've done some reading and I understand the point of pulse wave modulation over the pot and how it will give me torque at low rpm.
I have dug around in my junk electronics and found about 400 Watts worth (according to their datasheets) of various transistors.
The question I have is can I use...
I'm building a hybrid car for my kids. I'm up to speed control and hitting a few hurdles.
The set up is 4 x 12VDC motors, one to each wheel through a reduction gearbox.
I've wired them to a single bus, and have used 4 standard relays to deliver forward/reverse.
I have tried varying the speed...
