Abstract
A vibrator motor in a hair clipper has a stationary piece and a moving piece. The stationary piece has a primary leg and at least one secondary leg. The primary leg fits through an opening in a coil. A flange is then press fit onto the leg so that the coil is captured on the primary leg. The flange provides a magnetic pole face that is larger than the opening in the coil, which increases the efficiency of the motor.
