Abstract

A vibrator motor for electric hair clippers, massagers and the like includes a fixed magnetically permeable piece and a moving magnetically permeable piece. The fixed and moving pieces form a plurality of flux gap zones between selected corresponding surfaces of the fixed and moving pieces.
Each of the flux gap zones has an air gap formed between the selected corresponding surfaces of the fixed piece and the moving piece. The air gaps have a total gap surface area, and an apparent gap surface area. The apparent gap surface area can be measured by viewing a selected surface which forms each gap through a plane which is generally perpendicular to the direction of the path of oscillating motion of the moving piece, or through a selected cross-section of the fixed or moving piece which is perpendicular to the path. In this invention, the total gap surface area of the gap in at least one of the flux gap zones is greater than the apparent gap surface area of that gap or gaps.
