MUMBAI, India, Aug. 1 -- Intellectual Property India has published a patent application (202411006183 A) filed by Sona BLW Precision Forgings Limited, Gurgaon, Haryana, on Jan. 30, 2024, for 'integrated stator bobbin with sensor positioning and unilateral flip for rotating machines.'
Inventor(s) include David Prem Jose Godwin; Bharath Jaishankar; Thulasirajan Ganesan; Muruganandam Radhakrishnan; and Praveen Chakrapani Rao.
The application for the patent was published on Aug. 1, under issue no. 31/2025.
According to the abstract released by the Intellectual Property India: "The present disclosure relates to an electric vehicle hub motor, specifically focusing on the stator core (10), an integrated stator bobbin (20) with a hall sensor seating and a one-way flip (40). The integrated stator bobbin (20) provides insulation between the stator core and the stator windings. The integrated stator bobbin (20) features seating arrangements that include protrusions (60) that interact with holes (70) on a rotor positioning system, particularly a hall sensor PCB (30). These elements allow precise placement and easy removal for servicing of the hall sensor PCB (30). Additionally, the flip (40) mechanism on the stator bobbin (20) ensures secure retention of the stator winding coils and preventing displacement during motor vibrations. Overall, this disclosure enhances the efficiency and serviceability of electric vehicle components."
