Abstract
A thinly configured and brushless miniature DC micro motor that includes at least two substantially-flat motor cells that are aligned axially. Each motor cell comprises a stator coil having an elongate opening and passage for a rotor shaft, and a cross-polarized rotor magnet carried on the rotor shaft and received within the elongate opening. The micro motor also includes a frame substrate that fixably supports the stator coils of the motor cells while providing a bearing means for rotatably supporting the rotor shaft, so that selectively energizing one of the motor cells creates an electric current in the stator coil interacting with a magnetic field of the received rotor magnet to generate a torque between the rotor shaft and the frame substrate.
