which produces additional losses. it can also reach speeds as high as the ASM, by feeding the stator windings with an additional negative direct current. But such properties are only possible with a small number of pole pairs.The HYB has a high number of pole pairs, that is more ...
The paper is focused on comparison of power losses and a quality of output voltage in inverters fed drives for several types of inverters. The explored types of inverters were either based on hard switched inverter with dv/dt or sine-wave filter or the resonant or quasi resonant inverters. Th...
You might have come across various types of transformers in your daily life either knowingly or unknowingly. This article illustrates various transformer types. Before getting into classification, here is a brief introduction to the basic principle of the operation of transformers. Transformers are devic...
, Harmonic Distortion, and harmonic energy losses cost. The load is Induction Motor with Adjustable Speed Drive (ASD) because the Induction Motor with Adjustable Speed Drive (ASD) is one of electronic device causes harmonics. The voltage sources in this research are sine wave, square wave and ...
Because current flow through a capacitor results in self-heating due to ohmic and dielectric losses, the amount of current flow a given device can tolerate is finite, and is influenced by environmental conditions. Lifetime Many capacitors, aluminum types in particular, possess strong wear ...
as electromagnetic induction, but the construction is somewhat differentiated and also depends on the application for which these relays are selected. DC relays are employed with a freewheeling diode to de-energize the coil, and the AC relays use laminated cores to prevent eddy current losses. ...
Advances and integration of biochemistry, cell biology, molecular biology, and genetics have led to a better fundamental understanding of cancer biology and the causes for many types of cancer. Cancer is now thought to originate following either the “cancer stem cell hypothesis” or the “stochasti...

In a high-speed electrical machine, the rotor in normal operation experiences various types of loadings, such as centrifugal forces from the rotation, temperature gradients from the operational environment, losses generated in the electrical machine and loads from the process. A failure related to ...
In this paper, different induction machine soft-start profiles are shown, and comparisons of starting times, torque profiles, and heating losses are made. Discussion of these results and conclusions as to the near-optimum types of profiles are delineated based on peak torque, starting times, and...
