MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202617092773 A) filed by Nikkiso Co. , Ltd. on July 30, 2026, for Motor Bearing Wear Monitoring Device, Disconnection Detection Program, Disconnection Estimation Program, And Disconnection Detection Method.
Inventor includes Tanaka Takuya.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: The present invention safely confirms the presence/absence of the disconnection of detection coils without stopping a canned motor pump. A motor bearing wear monitoring device 5 according to the present invention monitors the wear state of a bearing on the basis of detection signals of a plurality of detection coils C1-C8 which detect a magnetic flux change corresponding to a mechanical positional change of a rotor 36 with respect to a stator 37. The motor bearing wear monitoring device comprises: a threshold value storage unit 53b; an acquisition unit 532 for acquiring radial path signals flowing through radial signal paths L1, L2 and thrust path signals flowing through thrust signal paths L3, L4; and a disconnection detection unit 535 for detecting the presence/absence of disconnection between the detection coils and the corresponding radial signal paths and thrust signal paths. The disconnection detection unit detects the presence/absence of disconnection between the detection coils and corresponding radial signal paths and thrust signal paths on the basis of respective voltage values of the radial path signals and the thrust path signals, radial threshold values, and thrust threshold values.
