CYLINDRICAL BRUSHLESS MOTOR

摘要

PURPOSE:To generate vibration simply with a motor without external eccentric weight, in a cylindrical brushless motor used for the vibration generation source of a portable communication device or the like. CONSTITUTION:A cylindrical brushless motor capable of generating vibration with a motor alone without an external eccentric weight, which was required before, can be gotten by fixing a cylindrical magnet 3 and a back yoke 6 with a metallic bearing 2a so as to keep magnetic balance constant, and constituting the assembly of a rotor so that it may have unbalance by rotation.
