Hi every one I need help and guide for how to use step motor, I am very new. I want to use pic to control step motor and also increase the speed to maximum. I am using Mikroc
 

Please clarify the stepper motor size (current and voltage), the driver you are going to use, and the desired step size and speed.

I am using SANYO 103H5208-1242, 1.8/STEP. I am going to use L298N as driver, for the the speed at least 5 rps . I don't know that am I possible to do this.

1-500x500.jpg This is the picture of the step motor that I am using.
 

It should be able to do 5 RPS or 300RPM. Next question. What are the hardware you are planning to use?
 

5 RPS it's ok, I am planning to use any PIC micro controller
 

Because you already have a driver, the problem is simple. How you are going to setup the driver? Have you already done that?
 

Interfacing-Bipolar-Stepper-Motor-with-8051-using-L293D.jpg yes I am using the procedure that shown in attached image. but I can get max speed. if I delay 5ms it's still very slow.
 

if I delay 5ms it's still very slow.

Own a pocket calculator? 5 ms delay = 200 Hz step rate = 1 rps for a 1.8degree step motor in full step operation.

=> 1 kHz step rate required for 5 rps. I guess the motor won't support 1 kHz start/stop frequency with 12V supply, most likely you need an acceleration ramp.
 

but actually what I see the motor move very slow
 

The delay determines the rotational speed; it is the time between the pulses and longer the delay, the slower the rotation. You try with these values: 2ms, 5ms and 10ms and see the effect.
