INSULATOR, AND STATOR AND MOTOR PROVIDED WITH SAME

摘要

In the present invention, an insulator (21) is provided with a main section (21b), locking sections (21a), and an opening section (S). The main section (21b) covers parts of a stator core (20) wrapped by coils (23), insulating the stator core (20) and the coils (23). The locking sections (21a) are disposed at the end of the part of the main section (21b) wrapped by the coils (23), locking the coils (23) onto the main section (21b). The opening section (S) is formed so as to expose the coils (23) to a portion of the locking sections (21a) on the side of the coils (23) to which cooling oil is supplied to cool the coils (23).
