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. The flange is press fit in a single operation by pressing a primary prong into a primary socket, and pressing two secondary prongs into secondary sockets. The secondary prongs are guided inwardly as they enter the secondary sockets, which closes the primary socket around the primary prong. A drive arm is secured to an arm of the moving piece. The arm is angled in relation to the drive arm to put even pressure on the moving blade in the hair clipper.
