MUMBAI, India, Aug. 12 -- Intellectual Property India has published a patent application (202647091936 A) filed by Ge Renewable Technologies on July 29, 2026, for Method And Device For Estimating The Temperature Of A Rotor.
Inventors include Schwery, Alexander; Baumeister, Stefan Albert; Yim, Eunok; and Sari, Gkhan.
The application for the patent was published on August 07, 2026, under issue no. 32/2026.
Abstract: The invention concerns a method for estimating and/or predicting at least the temperature of asynchronous or induction machine, for example a DFIM, connected to a grid, said rotor comprising : - a stack of steel laminations (25), each steel lamination comprising an inner part (26), also called the yoke, surrounded by teeth (28); - a rotor winding (32), integrated between teeth (28), in which the rotor currents flow, the method comprising: a) a step of selecting one or more steel laminations of said stack of steel laminations, b) a step of selecting at least one node on each of said selected steel laminations in the yoke (26) and/or in the teeth (28) and/or in the rotor winding (32), c) then a step of estimating and/or predicting at least one temperature of said rotor, based on the balance of the power that flows in said at least one node, and that is dissipated by the at least one node.
