Miniature motor

摘要

A miniature electric motor comprises a two-pole stator (1), and a rotor having at least three salient poles each having a core (8) with flanges (11) extending toward both sides thereof. The rotor is adapted to apparently form a two-pole construction by cutting off at least the tip of a flange (11) on either side on a part or all the salient rotor pole cores, thereby limiting the spontaneous-stop angular positions of the rotor to tow. One insulating spacer is provided between a plurality of commutator segments of the commutator to come in contact with one of two brushes when the rotor is at a spontaneous-stop angular position.
