摘要： Techniques for motor magnet degradation controls and diagnostics are disclosed. An exemplary technique determines q-axis current, d-axis current, q-axis voltage, and/or d-axis voltage of a permanent magnet motor based upon sensed current and voltage information of the motor. This information is utilized to determine flux information. The flux information is utilized in evaluating collective state conditions of a plurality of motor magnets and evaluating localized state conditions of a subset of the plurality of motor magnets. The evaluations can be used to identify degradation or damage to one or more of the magnets which may occur as a result of elevated temperature conditions, physical degradation, or chemical degradation.

摘要： A maximum current value determination unit determines the maximum current value of a permanent magnet synchronous motor in order to prevent irreversible demagnetization of a permanent magnet of the permanent magnet synchronous motor from occurring due to transient current occurring at the time of short-circuiting of three phases, based on one of a set of irreversible demagnetization causing current value corresponding to permanent magnet temperature and the transient current occurring at the time of the short-circuiting of three phases, and a set of irreversible demagnetization causing magnetic field intensity corresponding to the permanent magnet temperature and demagnetization field intensity of the permanent magnet of the permanent magnet synchronous motor occurring at the time of the short-circuiting of three phases. A current control unit controls the current of the permanent magnet synchronous motor so that the current value of the permanent magnet synchronous motor is less than the maximum current value.
