How to start a motor
he longest journey may begin with a single step, but, in the case of myosin motor proteins moving along actin filaments, the start of the walking stride has been nearly impossible to observe. Now Burgess et al., reporting on page 983, reveal the prepower stroke conformation of myosin on actin, clearing a major hurdle to understanding myosin activity. Previous work on myosin has focused primaril...
متن کاملA start-up method for a speed sensorless stator-flux-oriented vector-controlled induction motor drive
This letter describes a zero-speed start-up method of a speed sensorless stator-flux-oriented direct vector-controlled induction motor drive with the help of a machine current model that does not use any speed signal. The machine starts smoothly with vector control at finite developed torque and then transitions to the standard direct vector-control mode with the voltage model signals as the sp...
متن کاملIntelligent Induction Motor Drive
Electrical drives play an important role in rapidly growing industrial era, so the controlling of electrical drives is also important. Variable speed drives are the major part of power system, microelectronic, power plant and so on. Conventional controlling methods of electrical drives needed mathematical model of control process which was very tedious, that problem is solved by artificial inte...
متن کاملEfficiency Improvement of Induction Motor using Fuzzy-Genetic Algorithm
In most industrial zones, electric energy is one of the most important energy sources. Since electrical motors are the main energy consumers of industrial factories, consumption optimization in these motors can be considered as a main option related to energy saving. One very effective way to reduce the consumption of these equipment is to use a motor speed controllers or drives. Since the loss...
متن کاملPolyphase Antialiasing in Enlargements
ABSTRACT Changing resolution of images is a common operation. It is also common to use simple, i.e., small interpolation kernels satisfying some ”smoothness” qualities that are determined in the spatial domain. Typical applications use linear interpolation or piecewise cubic interpolation. These are popular since the interpolation kernels are small and the results are acceptable. However, since...
