It is well known that the number of broken bars and varying load affect on the amplitudes of specific harmonic components in the process analysis of induction motors under broken rotor bars. The location of broken bars is an important factor which af

Unfortunately, motor current signature analysis (MCSA) cannot detect the small degrees of the purely static eccentricity (SE) defects, while the air-gap magnetic flux signature analysis (FSA) is applied successfully. The simulation results are obtain

The electrical conductivity and thermoelectric power of CaO (2 and 2.6 mol%)-doped Ni 1 − x O single crystals have been measured in the temperature range 1000–1400 °C, as a function of oxygen partial pressure. These results show that Ca 2 + lead

The growth of oxide scales on Ce02-coated Ni polycrystals, in the temperature range 800–1200 °C, is analyzed taking into account both the transport properties of Ce-doped Ni1-xO single crystals, under non-equilibrium conditions, and a formal analy
