Increase Torque and Speed In Stepper Motor

In most contest people using stepper motors struggle to make a confortable run due to the slow speed of the stepper motor and a poor torque . Unipolar motors have lesser power than their bi-polar counterparts but then there are ways to make your unipolar stepper work better than what it does now.

First You can have a look at the stepper motor control mechanism here
so in that post we’ve seen that the pulses are given in the order as below.

1000
0100
0010
0001

Now this will do a good job and give you a smooth running robot. But another good alternative to run your unipolar motor with greater torque and speed is to give the pulse the other way as below

1100
0110
0011
1001

This sequence will do the magic for you. Bu the robot will have a bit rough run compared to the single line sequence given previously.The two line drive will show you how fast your steppers can run with an appreciable torque.

Try it.

    What are the parameters we have to consider while selecting a stepper motor

      torque,voltage and current

        and step angle

    I should be using a bipolar instead for my project for greater torque.

    But since I don’t have one, this code tip works in a pinch!

    Thanks!
