MUMBAI, India, Oct. 11 -- Intellectual Property India has published a patent application (202517090316 A) filed by Fujitsu General Limited, Kanagawa, Japan, on Sept. 22, for 'electric motor.'
Inventor(s) include Hasegawa, Tomooki.
The application for the patent was published on Oct. 10, under issue no. 41/2025.
According to the abstract released by the Intellectual Property India: "An electric motor in which the number of pole pairs of magnetic pole parts is m, the number of a plurality of teeth is 3m, and a rotor core has non-magnetic parts continuing from each of two end parts of a permanent magnet. Each magnetic pole part has a magnetic pole outer peripheral surface formed on an outer peripheral surface between a first boundary line and a second boundary line that pass through a rotation center (O) of a rotor and an outer peripheral end of each non-magnetic part in the radial direction of the rotor core. The magnetic pole outer peripheral surface has a front-side outer peripheral surface (29-F) positioned on the front side in the rotation direction (R) of the rotor relative to a d-axis, and a rear-side outer peripheral surface (29-R) positioned on the rear side in the rotation direction (R) relative to the d-axis. When the magnetic pole part is virtually folded back along the d-axis in the plane, and the front-side outer peripheral surface (29-F) is overlapped on the rear-side outer peripheral surface (29-R), the front-side outer peripheral surface (29-F) has a small-diameter outer peripheral surface (34) positioned further inward than the rear-side outer peripheral surface (29-R) in the radial direction."
The patent application was internationally filed on Feb. 13, 2024, under International application No.PCT/JP2024/004773.
