电动机的控制装置
摘要：
本发明提供一种电动机的控制装置，通过使根据惯量设定的加减速时间常数处于适当的范围，能够可靠地防止被驱动体以过快的加速度进行移动的情形。驱动工件(被驱动体)(W)的电动机(10)的控制装置(2)具备：惯量推定部(22)，其根据电动机的反馈信息(转矩、电流)来推定惯量；计算部(31)，其根据由惯量推定部推定出的推定惯量来计算电动机的加减速时间常数；存储部(32)，其存储至少一个已知实际惯量与推定惯量的差值即惯量差值和对应于实际惯量的实际加减速时间常数与根据推定惯量计算出的加减速时间常数的差值即时间常数差值以及校正部(33)，其使用由存储部存储的惯量差值和时间常数差值来校正由计算部计算出的加减速时间常数。
摘要（英）：

A controller of a motor that drives a driven body includes: an inertia estimating unit that estimates inertia on the basis of feedback information (torque and current) of the motor; a computing unit that computes an acceleration or deceleration time constant of the motor from the estimation inertia estimated by the inertia estimating unit; a storage unit that stores an inertia difference which is a difference between the estimation inertia and at least one known actual inertia and a time constant difference which is a difference between an actual acceleration or deceleration time constant corresponding to the actual inertia and an acceleration or deceleration time constant calculated on the basis of the estimation inertia; and a correction unit that corrects the acceleration or deceleration time constant calculated by the computing unit using the inertia difference and the time constant difference stored in the storage unit.
