Stepper Motor Control Using LabVIEW AND NI-myRIO

In the current scenario, stepper motors are being used for diverse applications due to its flexibility and ease of control. This paper deals with the control of stepper motor using NI myRIO, because it is less complex to work with LabVIEW programming, which is pretty simple. The pulse required to run the stepper motor is generated using NI myRIO and interfaced with LabVIEW with the help of code generated in the system. The supply voltage is given to the motor through a voltage driver circuit and the motor’s speed is controlled by varying the time delay in the LabVIEW program simulation specifications. Here, unipolar stepper motor is taken into consideration and wave drive or full step drive method is used, since this type of method is easy to implement. Position sensors may get affected by EMI and temperature so we are going in for sensor less control. This mechanical motion obtained using the stepper motor can be used in various industrial and real time applications as well.
