Exposure of workers to electric and magnetic fields from radiofrequency dielectric heaters (RF heaters) to process polyvinyl chloride material was surveyed. Measurements of electric and magnetic field strengths were made in 10 workers operating 7 RF heaters at 3 plants in Japan. Six of the RF heaters are of the sewing machine type and the other is of the shuttle tray type. In all the RF heaters...

This paper presents a methodology of rapid testing for different control algorithms of electrical drives with inverter-fed induction motors used for the propulsion of hybrid electric vehicles. For analysis, modeling and off-line simulation of the vehicle operations conditions, and also for the testing in real time of the control algorithm performance certain hardware/software products COTS (ADV...

Objective: In this article, a numerical study is conducted on mixing of two fluids in the liquid phase with two different concentrations of a chemical species in the electro-osmotic flow. Methods: The base liquid is an electrolyte which flows in a two-dimensional micro-channel having electrically charged walls. Lorentz electric force, which is used as stimulating flow factor, is created by appl...

This paper presents an approach to calculate the copper and core losses caused by harmonics of the PWM of a voltage source inverter. For the analysis some models of the Smart Electric Drives (SED) library, and additionally, a Modelica library for modeling AC circuits by means of electric time phasors, are used. With the proposed analysis the influence of space phasor PWM signals on the machine ...

In this paper, we focus on the frequent glitches of general family cars. Based on the Neural Network theory and combining with the Micro-chip processor technology, we design an expert system-‘‘Integrated Cars Repairing Tools” (ICRT) and the size of the proposed ICRT is quite small and achieves the following attractive functions: (1) Portable Electric-jack, (2) Electric Tire-pressure-meter, (3) ...

The hybrid vehicle control problem at the highest level is termed the Energy Management Strategy (EMS). This paper presents a new, and simple RuleBased (RB) EMS, whereby maximum power level of the electric machine during pure electric driving is the control design variable. This maximum power level determines the overall power -, and efficiency specifications of the electric machine. A RB EMS c...

The electric thickness of the semi-finished radome may not meet the requirement for the electromagnetic performance because it varies with both the geometry thickness and the electric inductivity of the radome. One way to obtain the required value of the electric thickness is to compensate the electric thickness error by modifying the wall thickness of the radome. To this end, a grinding machin...
