This paper aims to developed the permanent-magnet synchronous motor (PMSM) with six-phase driver by using a field programmable logic gate array (FPGA) chip. The stator of the PMSM is 12-slot six-phase winding structure, and the rotor is 10-pole. The resolver is placed on the PMSM in order to detect and feedback rotor magnetic pole angle position and rotational speed via resolver to digital converter (RDC) circuit. Then RDC convert the rotor rotation coordinate system into the q-d axis mode. Additionally, three current hall sensor are placed after MOSFET in order to feedback the six-phase current and convert the six-phase current into two sets of q-d axis currents. It use the q-d axis current closed-loop control and speed closed-loop control to complete the six-phase motor drive system. Lastly, the voltage space vector pulse-width modulation (VSVPWM) was adopted to improve the utilization rate of the dc-link voltage of the system.
