Title:
MOTOR STATE DETERMINATION DEVICE, MOTOR STATE DETERMINATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/184187
Kind Code:
A1
Abstract:
This motor state determination device 50 is provided with a physical quantity value range determination unit 56A, a transient period determination unit 56B, and a steady state determination unit 56C. The physical quantity value range determination unit 56A determines a physical quantity value range on the basis of a frequency distribution of the physical quantity value. The transient period determination unit 56B determines a transient period UT by using a temporal change in the physical quantity value and the physical quantity value range. The steady state determination unit 56C determines whether a motor 10 is in the steady state by using the transient period UT, the physical quantity value range, and the physical quantity value.
