Do you understand how a chopper driver works?i will use pic with L298.
so i think that 40v with 10 a is ok.
You keep saying regulated. You really don't need regulated. You could build an unregulated supply that output perhaps 36v, and just let the chopper drive take care of the rest.can u help me with design this power supply , i know that i need transformer , bridge , some cap and regulator.
there are 3 way to control the 6 wire stepper " torch only , speed, torch with speed " .portd = 0b01010000; Delay_ms(250);
portd = 0b10010000; Delay_ms(250);
portd = 0b10100000; Delay_ms(250);
portd = 0b01100000; Delay_ms(250);
You're not bothering me. If I sound irritated, I apologize; I have several things going on both on the board and where I am.sorry if i Bother you .
Bipolar is harder to understand than unipolar. Have a read through that Application Note I linked to if my last reply.what is better bipolar mode or unipolar mode, because i went speed and torque.
It depends on a number of things. Have you looked over at CNCzone.com? Lots of folks on there using various software packages, might even be some that have your motors.and what the best ic to do that? " i will use pic to send step ... "
Hmm - have you looked at Roman Blacks' LiniStepper project?i use pic in my project to receive data from serial port and make some operation with it, so the pic will have alot of pin dont use so i went to use it ...
