Document Type and Number:
Japanese Patent JP6636206
Kind Code:
B2
Abstract:
Provided are an electric motor torque pulsation correction device, an electric motor torque pulsation correction method, an elevator control device capable of correcting torque pulsation with a simple configuration. A frequency analysis is performed on a specific frequency component of the rotational speed of an electric motor, and the torque pulsation of the electric motor is estimated on the basis of the result of the frequency analysis. In this case, the amplitude or the phase of the torque pulsation is estimated as a function of current on the basis of the results of the frequency analysis obtained under multiple conditions having different current conditions. Since the torque pulsation is corrected by the obtained function, the torque pulsation of the electric motor can be corrected with a simple configuration.
