Stepper Motor Control: Data

Testing Stepper Motor Control
           With the circuit assembled and the PIC programmed it is time to take a look at what it looks like when we run it. Stepper motors typically make a nice hum as they run. You'll hear this in the video.
           The LED turns off when the motor goes full speed, it turns on when the speed is slowed down.

           You can see that full speed is not very fast, especially if you compare it to what full speed on dc motors is. However, stepper motors aren't meant for speed, but accuracy. Each 'step' on this motor is 0.9°, which means it can be turned 90° with 99.9% precision. Something a dc motor doesn't have a chance doing.
