I m using L239D driver to drive my stepper motor. My motor rotate very slow. 30sec/rotation. How to increase the speed of my motor. Have tried reduce the delay loop to increase but it doesnt work. I need your advice and help on this.Thanks
Hey thanks alot i went through the tutorial
But my doubt is will there be problem becos i connect my Motor directly to my Motor Driver. If i m not wrong this connection should be inside the Driver motor rite?
The L239D is more suited for bipolar steppers, but as far as I'm aware it can be used for unipolar as well, although you're wasting half of the chip. Post a drawing of how you've connected it all up.
Are you guys sure it isn't a L293d chip? If it is don't you have to change the frequency of the input signal to make the motor step/turn faster? That's the way most stepper drivers work. Also the L293d has 600mA output where a L293 has 1A output.

You need to sort your delay out, so you know what the delay actually is, and understand how to adjust it's delay - altering BOTH isn't going to work correctly.
right now i am working on stepper motor and i want to increase stepper motor rpm up to 1000 and i am using 1.8 step angle stepper motor, so plz tell me how to increase stepper motor speed.
