Abstract This paper proposes the prediction method of differential mode noise transmitted to the input power of a single‐phase inverter in a high‐frequency model. A high‐frequency equivalent circuit considering the parasitic impedance is proposed. This paper presents a method to measure the parasitic impedance included in the DC link capacitor and ...

Abstract This paper presents an analytical model of a dual‐stator spoke‐type permanent magnet (DSSTPM) synchronous machines accounting for tooth‐tips. Based on the two‐dimensional (2‐D) subdomain technique, the field domain of DSSTPM machine is divided into seven sub‐regions, that is, permanent magnet (PM), outer/inner air gaps, slots and slot openings.

A framework for statistical design of a brushless DC motor considering efficiency maximisation
Abstract In this study, a framework for statistical design of a brushless DC (BLDC) motor is proposed in order to maximise yield while keeping efficiency as high as possible and the non‐linear constraints, that is, limitations of flux density, current density and physical dimensions, satisfied. The proposed yield maximisation method has two major steps:

Abstract High‐speed railway (HSR) presents the characteristics of a heavy load, large traction current, and ballastless track‐bed. As the 'neural network' of the signalling system, the line‐side signal cable may threaten both human safety and control information transmission for an HSR operation when interfered with by a strong traction current.

Simulation of the Electrostatic Distribution in the Proximity Focusing Structure of an EBCMOS
The electrostatic distribution of an electron bombarded CMOS (EBCMOS) was simulated by Ansoft Maxwell 3D software. Specifically, we studied how the electrostatic distribution was affected by the structure of a back-side bombarded CMOS (BSB-CMOS) and the ...

Energy harvesting approach for trackside health monitoring devices in railroads
Abstract Design, modelling, simulation and lab test of a trackside electromagnetic energy harvesting (TEEH) approach for an AC electrified railway is provided in this study. By collecting the electromagnetic energy inspired from track current, an alternative energy source along the trackside can be achieved, which is not sensitive to weather and ...

Coaxial Atomic Force Microscope Tweezers [PDF]
We demonstrate coaxial atomic force microscope (AFM) tweezers that can trap and place small objects using dielectrophoresis (DEP). An attractive force is generated at the tip of a coaxial AFM probe by applying a radio frequency voltage between the center

Abstract To improve the efficiency, a 13 kW used vehicle permanent magnet synchronous motor was remanufactured, whose stator core was replaced by a combination of amorphous alloy laminations and silicon steel laminations. But the speed regulation ability with field weakening of the remanufactured motor limits its development towards high speed ...

A selective harmonic elimination method of modified packed u‐cells (MPUC) inverter fed induction motor built on modified multiverse optimizer (MMVO) algorithm is put forward. The proposed method adopts the MMVO algorithm to search the optimal solution in the SHEPWM equations through the two processes of exploring the optimal solution distribution and ...
