电动机控制装置
摘要：
运算或输出电动机的负载信息的电动机控制装置(30)具有：存储部(313)，其预先存储用于负载信息的运算的变量、和根据电动机输出或电动机转矩的实测值求出的函数或者表；和负载仪运算部(311)，其使用存储到存储部(313)中的函数或者表和用于负载信息的运算的变量进行负载信息的运算。根据上述结构，为了在包含电动机的非线性控制区域在内的整个电动机速度范围内实时地正确表示电动机的负载状态，对负载仪进行计算，使用计算值来控制电动机，并在显示装置中进行显示。
摘要（英）：

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.
