I was wondering if any one new any good ways to connect a computer to a motor. I need to be able to send signals to the motor from a computer.

 

There are good ways, but they are not cheap, normally.
Here are some examples: http://www.digikey.com/product-sear...=1&stock=1&quantity=0&ptm=0&fid=0&pageSize=25

Since you are the one who knows the specs on the motor, you are the one who will have to find the hardware to interface pc to motor.

 

Gecko's or Larkin Viper.

It really depends on what type of motor, and how much control you need over it.

It could be done with a single $0.50 MOSFET- to turn a small DC motor on and off, or you could use a complete motion control unit costing thousands. Define the the task.

 

A single stepper motor and a step/dir drive + P.Supply running Mach3 through the P.P. would cost around $300.00 - $500.00, any other mechanics of course is over and above this.
A servo motor with encoder would be up to around half again.
This is if you want to control speed, accel/decel and position.
Deals can be found on ebay, but generally you get what you pay for.

Using black duct tape, tape the computer to the motor. Although this answer is flippant, it answers the question asked, so maybe you need to be ore descriptive in your question.

 

I was looking to drive a stepper motor with a computer. I was hoping to use a computer to send an electrical signal (I could amplify signal) to the motor. I would probably use a stepper motor for this project.

 

Get a 9$ arduino clone from ebay and L293 motor driver.That will enable you to control the motor via PC/arduino.
