ELECTRIC SHAVER, AND ELECTROMAGNETIC ACTUATOR

Title:

ELECTRIC SHAVER, AND ELECTROMAGNETIC ACTUATOR

Document Type and Number:

WIPO Patent Application WO/2010/035728

Kind Code:

A1

Abstract:

Disclosed is an electromagnetic actuator (15) for an electric shaver, which comprises: movable elements (32a and 32b) made reciprocally movable in reciprocating directions (X); and a stator (31) including a stator core (33) having plural salient poles (33a to 33c) arrayed in the reciprocating directions, and a coil (34) wound on at least one of the salient poles. The magnetic path of a boundary portion between the movable elements and the stator is shifted in directions (Y) orthogonal to the reciprocating directions in at least one of the salient poles. As a result, the electromagnetic actuator periodically generates driving forces for driving the movable elements in the orthogonal directions while generating driving forces for reciprocating the movable elements in the reciprocating directions.
