In this paper, a mathematical model of permanent magnet synchronous motor (PMSM) fed by inverter with Direct Torque Control (DTC). Dynamic and steady state characteristics of PMSM is simulated and analyzed, electromagnetic torque response, speed response, locus of the stator flux linkage It is mathematically proven that the increase of electromagnetic torque in a permanent magnet motor is proper-tional the increase of the angle between the stator and rotor flux linkages, and, therefore, the fast torque response can be obtained by adjusting the rotating speed of the stator flux linkage as fast as possible. The simulation results verify the proposed control and also show that the torque response under DTC is much faster than the PWM current controlled drive.<br/>
