Title:
PERMANENT MAGNET EMBEDDED ROTOR OF MOTOR
Document Type and Number:
WIPO Patent Application WO/2013/175541
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a rotor of a motor having a structure that allows permanent magnets to be stably fixed by eliminating a problem of conventional rotors of motors, namely, the problem of an increase in imbalance of a permanent magnet embedded rotor of a motor due to instabilities of adhering capacity and adhesion area caused by stripping of an adhesive, which has been applied to the permanent magnets, at the edges of permanent magnet embedding holes. Each permanent magnet (4) is provided with an adhesive injection hole (7), which penetrates through the center section of a rotor core (1) in the axial direction of a rotary shaft (2), and adhesive ejection holes (8a, 8b), which are vertically connected to the adhesive injection hole (7) and formed on a surface having a long side in the axial direction of the rotary shaft (2) and a short side in the circumferential direction of the rotor core (1). An adhesive (10) for fixing the rotor core (1) to the permanent magnet (4) is ejected through the adhesive ejection holes (8a, 8b).
