Selection of a motor driver and controller

[fpharrington]

I am looking a motor driver and controller that I can use pretty quickly with a stepper motor.
What it to be USB or RS232 or similar
Want to send commands via a custom C program.
Any options or recommendations.

Hi,

First, here is a link to our Stepper Motor Controllers for your reference. Also, this Stepper Motors comparison table might help you choose an appropriate stepper controller for your application.
This being said, do you have a product code or a datasheet for the stepper you are planning to control ?
The things to consider while choosing a stepper controller :

1. Is the motor you selected unipolar or bipolar? Choose a stepper motor controller type accordingly, though a growing number are able to control both types. The number of leads is usually a dead give-away of the motor type: if the motor has 4 leads, then it is bipolar; should it have 6 or more leads, then it is unipolar.
2. Choose the motor controller voltage range to match your motor’s nominal voltage .
3. Find out how much current per coil your motor requires, and find out how much current (per coil) the stepper motor controller can provide.If you cannot find the current per coil, most manufacturers list the coil impedance, R . Using Ohms Law (V=IR), you can then calculate the current (I).
4. As with DC motor controllers, the control method is an important consideration.
