Claim 6:
7. A machine learning apparatus for learning a length of a current control period and a length of a magnetic-flux control period for the rotary machine control apparatus according to claim 1, the length of the current control period and the length of the magnetic-flux control period enabling at least one of reduction of an amount of increase in DC bus voltage in the power converter, reduction of a pulsation width of the DC bus voltage, reduction of a pulsation width of frequency of a magnetic flux vector in the rotary machine, and reduction of a pulsation width of an effective current value of an electric current flowing through the rotary machine, the machine learning apparatus comprising:
a learning data acquirer to acquire a value indicating the length of the current control period, a value indicating the length of the magnetic-flux control period, a frequency estimation value of the magnetic flux vector, and the effective current value;
a model generator to generate a learned model with use of a data set produced based on the value indicating the length of the current control period, the value indicating the length of the magnetic-flux control period, the frequency estimation value, and the effective current value; and
a learned model storage medium to store the learned model.
