Abstract
For flux map identification, a method applies an initial voltage to a motor. The motor is a salient motor. The method generates a flux map for the motor. The method iteratively applies a variable voltage to the motor. The variable voltage includes a constant current change calculated from the flux map. The method iteratively modifies the flux map.
