    Abstract: The importance of the Permanent Magnet Synchronous (PMSM) as flexible and trusted machines
that have capability to drives close loop for more much industrial applicationshas been presented in this study.
In order to increase the fast-dynamic response, the positioning sensors are engaged as feedback loop to
monitor the rest parameters. The space vector speed control of PMSM operating covers both torques and
variables in a wide speed range. An employed with PWM sinusoidal with high frequency equal 5000 Hz are
achieved. Simulation results shows the effectiveness and the feasibility of various pulse width modulation.
MATLAB is used for implementing and testing the discussed techniques in this study. The mathematical model
of the system devices including PMSM and inverter are done. The drives system objective is to achievea wide
speed range over speed control with good dynamic response.
