Abstract
A pivot motor has a stator and an armature. The armature has an assembly of two spaced permanent magnets and a triangular flux bridge on one end. Magnetic flux is generated by passing alternating current through an electrical coil in the stator. The flux flows through the permanent magnets to generate electromotive force that vibrates the armature. The triangular flux bridge adjacent the magnets facilitates the flux flow, increasing motor power under typical load conditions and motor efficiency.
