MUMBAI, India, Nov. 7 -- Intellectual Property India has published a patent application (202514022779 A) filed by Mitsuba Corporation, Gunma, Japan, on March 13, for 'motor device.'
Inventor(s) include Tozuka, Yosuke.
The application for the patent was published on Nov. 7, under issue no. 45/2025.
According to the abstract released by the Intellectual Property India: "An axial central part of a ring magnet (43) deviates to a side opposite to an abutment direction of an abutment member (44) against a first ball bearing (23), with respect to an axial central part of a stator core (31). Thus, by supplying drive current to a coil (34) and driving an electric motor part (20), magnetic attraction force (MF) can be generated that attempts to move a rotor (40) toward the other axial side. Due to the action of the magnetic attraction force (MF), the occurrence of rattling and deviation of the axial position of the rotor (40) can be eliminated. Consequently, a constant separation distance between the ring magnet (43) and Hall elements (Hu, Hv, and Hw) in the axial direction of the rotating shaft (41) can be maintained, and stable sensing can be performed while an increase in inertial mass is suppressed."
