High Precision Stepper Motor Controller Implementation on FPGA with GUI on LabVIEW

Arvind Kumar, Mrs. M. Valarmathi

Wireless stepper motor controller designed using Very High Speed Integrated Circuit Hardware Description Language (VHDL) and is implemented on SPARATAN Field Programmable Gate Array (FPGA). The proposed motor controller is controlled by using Pulse Width Modulation Technique (PWM) thus giving the very high precision. Due to high torque of stepper motor it is capable of handling the big industrial automation system. In this system GUI will be designed using LABVIEW to give the control parameter to the wireless connected stepper motor. Same system can also be used in the mobile robot, functioning in the hazardous area and can be very well equipped with the nuclear reactor to control the movement of control rod. One of the best use is to track solar energy because the resolution of stepper motor will be highly increased i.e. 0.915Ã?Â?.
