Abstract

PURPOSE:To simplify the construction of the bearing part and to enable the automatic oiling of oil-immersed wicks of an outer-rotor motor by a method wherein oil- immersed wick holding parts are provided on the supporting cylinder or on the bearing of the motor and blocks having gaps are provided between them. CONSTITUTION:Oil-immersed wick holding grooves 8A are formed on the inner circumference of a supporting cylinder 1A supporting a stator core of an outer-rotor motor, or on the outer circumference of a bearing 10 supporting rotation freely the rotor, and blocks C having respectively a minute gap of 0.2-0.5mm., for example, between the supporting cylinder 1A are provided, for example, at the neighborhood of the side part of rotor in the bearing 10 (at the left side in the figure). By this way, the automatic oiling and the prevention of protrusion of the oil-immersed wicks become possible.
