Since the conventional multi-coil motor system was merely applying the technology of the digital direct drive speaker, there was no feedback control, and it was unstable and inefficient driving against fluctuation of the load. Therefore, we propose a system applying vector control and space vector delta sigma modulator toconventional systems. MATLAB / simulink simulation and measurement show that this system can improve efficiency and optimize the system with the same performance as before.Key Words : delta-sigma modulator, PWM, space vector, vector control.
