<P>PROBLEM TO BE SOLVED: To highly precisely analyze residual voltage when three-phases are interrupted simultaneously, in a power source of a three-phase induction motor. <P>SOLUTION: The circuit constant, current I, torque T<SB>M</SB>and rotation speed ω<SB>M</SB>of the three-phase induction motor are obtained based on the voltage/current equation (S2) and the motion equations (S5, S6) of the three-phase induction motor and a load machine, to calculate the magnitude and the phase of the residual voltage based on the calculated results in time series. In this case, after the analysis of the three-phase induction motor during continuous operation, the magnitude and the phase of the residual voltage, with the power source having its three phase interrupted simultaneously, are analyzed in time series, using the analysis result as an initial value. <P>COPYRIGHT: (C)2008,JPO&INPIT |
