  • Method to improve adhesion of rotor magnets being embedded in an interior permanent magnet motor
    Patent number: 12683470
    Abstract: Disclosed herein is a method for improving the adhesive-based embedding of a permanent magnet (01) within a receiving cavity (02) in a rotor (03) of an interior permanent magnet motor, wherein metered quantities of adhesive are precisely applied at a pair of instances (04A and 4B) and another pair of instances (6A and 06B) to the permanent magnet (01) and its receiving cavity (02) respectively, whereby during the motion of insertion, the adhesive respectively present on the permanent magnet (01) and the receiving cavity (02) experience counter-shear and hence opposing displacement to consequently completely fill up the void space therebetween without overflow to result in said permanent magnet (01) being embedded, with improved adhesion, within in the rotor (03).
