In this paper, dual-rotor permanent magnet induction motor(DRPMIM) is studied to improve performance of usual induction motor(IM). Two-dimensional finite element model for DRPMIM is established by Maxwell Ansoft software, and electromagnetic characters of that was analyzed.Based on the rotating coordinate system, the mathematical model concerning DRPMIM, performance curves under the different l...

Sabit mıknatıslı senkron motorlar (SMSM) birçok özelliği bakımından değerlendirildiğinde literatürde avantajlı motor türlerinden birisidir. Rotorunda bulunan yüksek güç yoğunluğundaki mıknatıslarla bu diğer fırçalı motorlara göre avantaj sağlayan motorlardır. Ancak, karakteristik yapısından dolayı oluşan ve motorun çıkış momentini olumsuz etkileyen vuruntu momentine sahiptirler. Radyal akılı sü...

This paper analyzes the power loss of magnetically controlled reactor based on the basic theory of the electromagnetic field. In a variety of magnetic valve structure model as the object, physical simulation models of the reactor are built. Using Ansoft Maxwell simulation software, various magnetic valve structures of the reactor are studied by the analysis of the magnetic valve type reactor co...

Nowadays, sensor development focuses on miniaturization and non-contact measurement. According to the D-dot principle, a D-dot voltage sensor with a new structure was designed based on the differential D-dot sensor with a symmetrical structure, called an asymmetric open D-dot voltage sensor. It is easier to install. The electric field distribution of the sensor was analyzed through Ansoft Maxwe...

Mechanical parts such as gears and bearings used in mechanical equipment have a finite lifetime because of corrosion and wear. If the parts are in abnormal operation and is not detected, it may cause catastrophic component failure during operation. One effective approach to detect signs of potential failure of the mechanical equipment is to examine the debris particles in its lubricating oil. T...

Swallowable capsule endoscopy is used for non-invasive diagnosis of some gastrointestinal (GI) organs. However, control over the position of the capsule is a major unresolved issue. This study presents a design for steering the capsule based on magnetic levitation. The levitation is stabilized with the aid of a computer-aided feedback control system and diamagnetism. Peristaltic and gravitation...

Given the existence of detent force, positioning accuracy permanent magnet linear synchronous motor (PMLSM) with an iron core worsens in its application field precision drive. To address this problem, a method is proposed to weaken force PMLSM V-shaped tooth-slot structure. The models including cogging and end are established theoretically. analytical expressions obtained by analysing ripple ru...

permanent magnet synchronous generators (pmsgs) are novel generators which can be used in high-performance wind farms. high efficiency and flexibility in producing electricity from variable rotation make them good candidate for wind power applications. furthermore, because these kinds of generators have no excitation winding, there is no copper loss on rotor; hence, they can operate at high pow...
