Filed: 2002-06-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide an magnetic analysis computer for simplifying a task of inputting a current value and a direction of current and simplifying a task for computing a flux linkage of each phase.  <P>SOLUTION: A current setter 27 has a mathematics hard part 26 for stipulating mathematically a current direction of a wiring position in a coordinate system.

Since the connection sequence number is an ordinal number, a consecutive number is optimal. A magnetic computer unit automatically stipulates the current direction on the basis of a connection sequence number k of the element Ajk. The matrix representation is capable of expressing the phase and winding order uniformly, expressing the current value and the current direction uniformly by the matrix number and the column number, and does not need input for computing thereafter by inputting the matrix representation once. Thus the input task is simplified.  <P>COPYRIGHT: (C)2004,JPO
