Induction motors, as any other industrial products, have to comply with various requirements on noise levels. Therefore, it is essential to use an appropriate prediction tool to verify and optimize the design of an induction motor with respect to the acoustic performances. The paper will focus on the prediction of the magnetic noise generated and radiated by a specific motor. The challenge is ...

This paper presents the design and analysis of a high power radial flux Brushless DC motor for electro-mechanical actuation system. The motor is used for driving an electro-mechanical actuator of 20 ton capacity. Surface mounted, radially magnetized permanent magnet design is mostly preferred due to its ease of control, high efficiency and low maintenance. The motor under consideration is having ...

Plasma torches are used in processing of materials as well as in the energy industry for producing plasma. In a non-transferred arc plasma torch, an electric arc can be initiated by applying a direct current (DC) between the cathode and anode, both placed inside the torch. Then, the plasma is obtained by heating, ionizing and expanding a working gas, introduced into the chamber of the torch ...

Carbon fiber (CF) reinforced polymer composites (CFRP) have begun to replace Al-Zn-Mg alloys in applications which require high strength-to-weight ratios. The anisotropy of CFRP composites is a result of melt crystallized extrusion techniques that impart an inherent directionality to the CFs and the associated material’s properties. Electrical conductivity was modeled across the entire CF ...

Efforts involving simulation of transmission line networks necessitate the accurate values of the parameters of the lines. In this paper, as an attempt in estimating such parameters, the parameters of high voltage asymmetric power lines are calculated. In the process of estimation, the three phase equivalent circuit model is used. The resistance and inductance of such lines are dependent ...

The electric field plays a very important role in the electrospinning process, which needs to be seriously considered in the electrospinning configuration developing. High voltage involved in electrospinning process leads to difficulty in measuring the electric field. Numerical simulation is used to design the electric field, and experiments are carried out to validate the spinneret and ...
