Best IC for controling bipolar stepper motor

[PistolPete]

Hi;
I would like to know if anyone has some tips on controling bipolar
stepper motor. I going to be using Java to control its variable speed.
I would like to know if any one has dealt any particular IC that would
be great for my project. Mainly because I am building a mobile that
would be control over the parallel port. Thanx in advance.

Try the L293D; it has seperate logic and motor supply, and you can disable
the drivers; with PWM you can reduce the average current when the motor is
not stepping to save energy and to reduce heat, or to do microstepping.

It also has built in protection diodes, and if i remember correctly can
switch 3A@36V with adequate cooling.

Hi! Usually stepper motor ICs will be avaiiable for a reasonable cost
from the vendor who sells those motors...catch up with them and they
would help u with things...there are lots of considerations while
running stepper motors:

1. RPM
2. Angular rotation per step
3. Torque etc.

I dont know how, but even microcontrollers are used to control
steppers. L293D is mostly used to move DC motors forward and backward.
Changing speed is not suitable using these ICs. But for simple
applications, it can be used. Bye!
