several approaches are available to reduce pulsating torque components in permanent magnet motors. one of the known techniques is stator tooth shape modifications. this paper presents an integrated algorithm applicable for tooth shape optimization of permanent magnet motors. this method focuses on the reduced basis technique, finite element analysis and taguchi method and is conducted on tooth ...

multiple coupled circuit modeling of squirrel-cage induction motors, or winding function approach is the most detailed and complete analytical model used to analyze the performance of the faulty induction motors. this paper extends the above-mentioned model to a saturable model including variable degrees of the saturation effects using an appropriate air gap function and novel techniques for lo...

this paper presents developing an analytical model for flux switching motors. the motor is a class of variable reluctance motors that has two windings on stator; a field winding and an armature winding. due to saliency of both stator and rotor poles, accurate modeling is difficult which arises from the nonlinear behavior of the machine. this paper presents a simple model which is able to predic...

Nowadays, the most generated electrical energy is consumed by three-phase induction motors. Thus, in order to carry out preventive measurements and maintenances and eventually employing high-efficiency motors, the efficiency evaluation of induction motors is vital. In this paper, a novel and efficient method based on Improved Big Bang-Big Crunch (I-BB-BC) Algorithm is presented for efficiency e...

With the coming of aging societies, many elderly people have serious problems for their locomotion, because of the decline of the physical strength for walking. If they could not use their legs for walking, their physical strength would be weak gradually and they could not walk finally without assistance of other people or some assist system such as wheel chairs, etc. The walking using legs of ...

Intracellular transport is an essential function in eucaryotic cells, facilitated by motor proteins proteins converting chemical energy into kinetic energy. It is understood that motor proteins work in teams enabling unidirectional and bidirectional transport of intracellular cargo over long distances. Disruptions of the underlying transport mechanisms, often caused by mutations that alter sing...
