Abstract :
This paper presents a direct torque control scheme for permanent magnet synchronous motor (PMSM) drives, where current controllers followed by PWM or hysteresis comparator are not used. The switching table specific for a PMSM is derived. The experimental results show that the torque response is extremely fast and that the position sensor is not essential for the inner torque loop
