MUMBAI, India, Sept. 12 -- Intellectual Property India has published a patent application (202517080766 A) filed by Siemens Aktiengesellschaft, Munchen, Germany, on Aug. 26, for 'method for monitoring the state of an asynchronous motor.'
Inventor(s) include Behringer, Klaus; Pirstat, Daniel; and Zettner, Jurgen.
The application for the patent was published on Sept. 12, under issue no. 37/2025.
According to the abstract released by the Intellectual Property India: "The invention relates to a method for monitoring the state of an asynchronous motor (AM) which has a slip (s) and to which a feed voltage (U) with a feed frequency (f) is applied, having the following steps: - defining two or more different operating ranges (B) of the asynchronous motor (AM) as a function of the slip (s) and as a function of the feed frequency (f); - assigning, to each of the defined operating ranges (B), at least one respective corresponding anomaly detector (Ai-1, Ai, Ai+1) which is adapted so as to detect a malfunction (E) of the asynchronous motor (AM) in the respective operating range (B); - ascertaining the current operating range (B) of the asynchronous motor (AM); - activating the at least one anomaly detector (A) which is assigned to the current operating range (B) and monitoring the state of the asynchronous motor (AM) using the active anomaly detector (A); and - if an anomaly is detected by the active anomaly detector (A), generating a corresponding signal."
The patent application was internationally filed on Jan. 08, 2024, under International application No.PCT/EP2024/050289.
