In this paper, the torque ripple of consequent-pole PM machines (CPPMMs) is reduced by injecting 2nd order harmonic armature current. into stator coils. proposed method, based on machine back-emf spectrum and main load current, appropriate current obtained. An analytical model developed to obtain CPPMMs. addition, obtained used compute electromagnetic as a function currents. Validity verified u...

long-acting (depot) anti-psychotic injection (lai) is an essential component of the treatment of schizophrenia. in this editorial, the journal tries to give a short account of the current ideas and practical aspects of lai, with respect to the iranian experience. two categories of the long-acting injections are discussed mainly regarding their dosage, intervals of their injections and availabil...

This paper considers the carrier based signal injection method in three shunt sensing inverter (TSSI) for sensorless motor control and analyzes the loss according to the injection axis of the voltage signal. To remove both phase current and rotor position sensors, sensorless method and phase current reconstruction method can be simultaneously considered. However, the interaction between two met...
