Title:
MOTOR MONITORING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/075224
Kind Code:
A1
Abstract:
A motor monitoring device according to one aspect of the present disclosure comprises: a rotational speed acquisition unit that acquires the rotational speed of one or more motors driven by a plurality of alternatively used windings; an output value acquisition unit that acquires the output value of the motor(s); a winding identification unit that identifies the winding in use; a load characteristic acquisition unit that acquires load characteristic information about the winding identified by the winding identification unit for the motor(s); and a graph display unit that plots a marker indicating a combination of the rotational speed and the output value in a graph area of which one axis is the rotational speed and the other axis is the output value. The graph display unit includes: a graph area setting unit that, with regard to expected combinations of the rotational speed and the output value, divides the graph area into a plurality of load zones with different load levels on the basis of a plurality of the load characteristic information, and displays the plurality of load zones in an identifiable manner; and a plotting unit that plots the marker in the graph area.
