Title:
WINDING SWITCHING DEVICE AND WINDING SWITCHING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/009558
Kind Code:
A1
Abstract:
According to the present invention, a winding switching device for switching the connection states of a plurality of windings of a motor capable of switching the connection states of the plurality of windings between a first connection state and a second connection state, comprises: a detection unit that detects a zero-crossing point of a measurement value of a current sensor that measures the current flowing through the winding; and a switching unit that switches the connection states of the plurality of windings between the first connection state and the second connection state at a timing when the detection unit detects the zero-crossing point.
