摘要： A motor control apparatus 30 for computing or outputting motor load information, comprises: a storage unit 313 which stores a function or table obtained in advance based on parameters used for the computation of the load information and on an actually measured value of a motor output or motor torque; and a load meter computing unit 311 which computes the load information from the function or table stored in the storage unit 313 by using the parameters used for the computation of the load information. With the above configuration, the load meter is computed in such a manner as to accurately indicate the load condition of a motor in real time over the entire speed range of the motor including the nonlinear control region of the motor, and the motor is controlled using the thus computed value or the computed value is displayed on a display unit.

摘要： An excitation current processor of a current controller processes the excitation current corresponding to the magnetic flux instruction from the magnetic flux instruction processor. It multiplies this excitation current with a boost coefficient to obtain an excitation current instruction. Here, the boost coefficient is determined based on the difference obtained by subtracting the magnetic flux estimation value processed by the magnetic flux processor based on the excitation current feedback from the voltage conversion device from the magnetic flux instruction input from the magnetic flux instruction processor. Further, the boost coefficient can be found from the function of time from the start of the rise of the magnetic flux.
