Abstract

The purpose of this project is to develop a new solution for stepper motor control. This solution will be applied to high performance stepper motors for the new accelerator for the National Syncrotron Light Laboratory (LNLS). The solution is composed by the following elements: driver and controller. The driver has the power elements needed to activate the motor at the requested operation. The controller is responsible to process the information and indicate the next operation to be performed by the motor. The final motors are bipolar and the controller must operate 8 motor axes at the same time. The work methodology starts with a preliminary study of the state of the art in stepper motors control algorithms. The next step is to define the key elements for hardware design. Once defined the components, we will perform the hardware design, composed my schematics, printed circuit board layout and the bill of materials. The next step is the hardware prototyping and validation. The embedded software design is done in parallel with hardware design, using reference design boards to implement the studied algorithms, responsible for controlling and monitoring the operations. At the end, the final hardware and the final embedded software are integrated. This project will be initially applied to the equipment located at the LNLS's accelerator. But this technology has also applications in other important areas, such as industrial automation and scientific equipments, where the are important use of high performance stepper motors. And this project will also compliment the current Phi Innovations' activities in motor control, where the company already has a technology for brushless DC motors controller for medical applications.
