The article presents an analysis of the winding type influence on the efficiency of an induction motor. The aim of this work is to choose such a type of stator winding that the induction motor will have the best efficiency by employing minimum winding (copper) mass. Three types of stator windings were considered in the analysis: concentric single layer winding, concentric double layer winding a...

The purpose of this study is to explore new permanent magnet (PM) array and winding patterns to increase the magnetic flux density and thus to improve the force output of electromagnetic tubular linear machines. Design/methodology/approach – Based on investigations on various PM patterns, a novel dual Halbach PM ...

This paper presents the sensitivity analysis of the behavior of a synchronous machine using the winding function theory considering the effect of static air-gap eccentricity. The winding function theory as a method to calculate the inductances of synchronous machines from the geometry and the actual arranging of the windings is presented. Then, detailed numerical simulations are carried out to ...

In this paper, a new three-winding planar transformer design with the integrated leakage inductor is proposed for triple-active-bridge converter. It enables two output voltage levels: high (HV) port and low (LV) port. The primary secondary windings are split unevenly in both side legs while tertiary winding connected parallel. unique configuration enables: (i) enhanced efficiency volume; (ii) s...

Inductive magnetic probes are often used to measure oscillating magnetic fields in plasma.r3 The sensitivity of a magnetic probe to electrostatic potentials (“capacitive pickup”) is usually an important consideration. Centertapped construction of such a probe, shown in Fig. 1 (b), helps to minimize capacitive pickup with respect to a simply wound probe [Fig. 1 (a)]. This relies on the fact that...

Cable wound electric machines are used mainly for high voltage and direct-drive applications. They can be found in areas such as wind power, hydropower, wave power and high-voltage motors. Compared to conventional winding techniques, cable winding includes fewer manufacturing steps and is therefore likely to be better suited for automated production. Automation of the cable winding production s...

Detecting and removing minor faults in power transformer winding is essential because minor faults may develop and lead to major faults and finally irretrievable damages occur. In this paper in order to detect the position of short-circuit in the winding, frequency response of the input impedance of a power transformer is analyzed. Common short-circuits are categorized and the results are compa...

Filament winding is a process in which tensioned resin-impregnated continuous fibers are placed on a specified path on a mandrel. Automated systems have been adopted to deliver the fiber with a fixed level of accuracy. Process simulation is a very important question in automated applications. Moreover, the necessity to process complex shape objects leads to consider different alternatives to de...
