A hair clipper comprising: a housing, a stationary blade secured to the housing, the stationary blade having a row of cutting teeth, a moving blade having a row of complementary cutting teeth arranged so that hair that enters spaces between adjacent stationary cutting teeth is cut by reciprocating movement of the complementary teeth, and a vibrator motor secured to the housing and operably connected to the moving blade to cause the reciprocating movement, the vibrator motor comprising: a mechanical spring system secured to the housing, a stationary magnetically permeable piece secured to the housing, the stationary piece having a primary leg and at least one secondary leg, the primary leg having a first cross-sectional area in a mid-section and a primary pole face, the secondary leg having a secondary pole face, a complementary moving magnetically permeable piece secured on a proximate side to the mechanical spring system and having a general direction of movement towards and away from the stationary piece, the moving piece having a primary moving pole face and at least one secondary moving pole face, a drive arm secured to a distal side of the moving piece and the moving blade, and a coil on the primary leg of the stationary piece, the coil being located over the mid-section of the primary leg of the stationary piece and captured on the primary leg by the primary pole face, characterised in that the primary pole face has a second cross section area larger than the first cross sectional area, wherein the primary pole face comprises a separate flange secured to the mid-section of the primary leg of the stationary piece, the flange having the second cross-sectional area, and the coil having an open space having a third cross-sectional area larger than the first cross-sectional area and smaller than the second cross sectional area. a housing, a stationary blade secured to the housing, the stationary blade having a row of cutting teeth, a moving blade having a
