Popis:	Field Oriented Control in Permanent Magnet Synchronous Motor needs a quick computation in extremely short time to get an optimal efficiency and stability of the motor. The aim of this research is to present a fully integrated solution of inverse Park transformation by incorporating Coordinate Rotation Digital Computer, ARITHMETIC and Phase-locked Loop (PLL) module. But, the main problem in presenting such solution lies in completing the transformation within a limited clock cycles to pledge the steadiness of the motor where presently is the main issues of this industry. This research presents a transformation that works within 4 clock cycles with an execution time of 160ns of 24MHz frequency with an accuracy of 99.9 % which is the lowest computational cycle for the era.
