Advance angle simulation method and advance angle simulation program

摘要

PROBLEM TO BE SOLVED: To provide an advance simulation method and an advance simulation program which allow the optimum advance value to be obtained in three-dimensional magnetic field analysis for obtaining the efficiency of a motor on a computer.SOLUTION: An advance value and motor efficiency are computed on the basis of a converged position detection error obtained by: an input step of inputting required parameters; a three-dimensional magnetic field analysis processing step of performing three-dimensional magnetic field analysis processing on a computer on the basis of respective input parameters to obtain at least a magnetic flux density as a three-dimensional magnetic field analysis processing resu a position detection error computation step of computing a position detection error due to an influence of a magnetic flux density from a stator, of a position detection signal of a rotor based on a magnetic flux density of a magnet to be detected by position detection means, on the basis of the magnetic flux density of the magnet to be detected by position detection means; and a convergence determination step of determining whether the position detection error is converged or not by adding the position detection error to the advance value to repeat the three-dimensional magnetic field analysis processing step and the position detection error computation step.
