Remember the motors I have posted.
Well I have tested those except the steppers.
All the 2 wire ones have a good torque and speed. Once I get the tacho I can measure the RPM.
So for now I am planning to build a small winding machine to complete my woofers, doing this hand is really tiring.
All the motor can handle up to 24V , the big one takes (like a star body) more current around an amps or so and I cannot even hold the shaft while even at low RPM. as for my engraver I'll get the nema steppers u guys suggested, and I can buy them once the cable job is finished,
For now like to use one of the DC motors at the winding machine. The shaft and bobbin locking machs and reduction gear and the frame work is finalized.
All I need now is PWM controller that can rev up the motor from 0 to max RPM, Vcc will be 24V and current will be less than 3A.
I did a lot of search and nothing good came up except one at silicon chips 2008, issue 234. It has a very good PIC16F88 controller with enough current capability plus a counter, but for the detail they are asking for my credit card. And I cannot do that.
I like to ask you members that does any of you have a controller that I can use, if you don't mind, a PWM one is preferable.
I have the PICF88 if needed, but I guess logic will also do.
I thing the machine builders here will have something atleast I can modify.
I want to use 2 Wire DC motor as it is easier for me to make the machine and all the rest of assembling is finalized.
Just for your info I am attaching the power drivers that I have.
L297, 1 pc
L298, 1 pc
L6203, 4 pc
MPM3003, 1 Pc
MPM3004, 2 Pc
These H bridges and DMOS full bridges.
I can use these as the out put power drives.
So please, if any one have any thing, can you share it.
If all fails I guess I will pay silicon, but this is the last resort, and after this I guess I have to renew my Credit card.
PS . I can't seem to attach more than 2 PDF's
Thanks
