Consequently, excitation rotor field coil directly from stator coil is suggested.
During the induction start the excitation winding is usually short-circuit on resistive resistance value of 5-10 Q, and it almost does not participate in the creation of electromagnetic torque.
Chen and Lai made a stable-state performance analysis of the standalone IG loaded with unbalanced loads and made self-excitation with unbalanced excitation capacitors [16].
0), the common interval covered by the time series for all models of excitation, available at the web site of the International Earth Rotation and Reference Systems Service (IERS).
The method described here treats the excitation sources of wind noise as micro forces in terms of wall pressure fluctuations calculated by computational fluid dynamics (CFD) without separating them into pseudo-sound and acoustic waves.
Some as yet unknown and powerful excitation from the sun strips them of their normal quota of electrons.
relative separation between antenna elements, excitation amplitude of each of the antenna elements, excitation phase of each antenna elements, and radiation pattern of each of the antenna elements [1].
The IN-UVI supplies a highly regulated bridge excitation voltage for the transducer or load cell and a host of features Including: improved signal to noise ratio, two selectable excitation voltages, wide zero adjustment range, and an Isolated shunt calibration relay for quick field setup.
In 2009, Israr and Atepor [8] investigated nonlinear vibration of an isotropic cracked plate subjected to transverse harmonic excitation, both analytically and experimentally.
Excitation control system has attracted great attention mainly due to its abilities to ensure the stability of power system.
This is based on the excitation of a particular higher vibration mode of a turning tool, which leads to the reduction of deleterious vibrations in the machine-tool-work piece system through intensification of internal energy dissipation in the tool material.
