in the present study, field oriented control of step motor implementation has been analyzed sothat it can make a sensorless control. efficiency and facilities of step motor is more than othertypes of electromotor. therefore, the numbers of mechanisms and different types of turning canbe made into them. also controlling these motors is easier than other available motors. steppingmotor has been d...
A group of novel heterocyclic arylsulfonamide derivatives were synthesized by three steps process using the organic and inorganic catalyst in less solvent at ambient temperature. One out three-steps process, one-pot multiple component reaction reusable catalyst. These compounds reactions proceed through Knoevenagel condensation accompanied Michael addition to obtaining suspicious products. The ...
