SINGLE PHASE BLSLDC DYNAMO-TYPE MOTOR ASSEMBLY HAVING INNER GEARING-DRIVING ROTOR AND METHOD OF DRIVING USING THEREOF

A single phase BLSLDC(Brushless Sensorless Direct current) dynamo-type motor assembly having an inner wheel driving rotor and a driving method using the same are provided to reduce a magnetic force by constantly maintaining a direction of a magnetic field of a permanent magnet in an operation aperture linearly. A rotor yoke(20) has a permanent magnet having a shaft connection hole on a center and a core receiving space on an inner side wall. A second protrusion(22) is formed on a circumferential region of both ends of the permanent magnet in the rotor yoke(20). A stator yoke(30) surrounds an outer circumferential plane of the rotor yoke(20). A shaft assembly(50) has a shaft which is rotatably connected to the shaft connection hole of the rotor yoke(20). A first protrusion(34) is protrusively formed toward the rotor yoke(20) on a central part of the stator yoke(30). A third protrusion(35) forms a second transfer aperture by being protruded to be opposite to the second protrusion(22) on both sides of the stator yoke(30). A core(C) is installed between a first transfer aperture formed as much as a thickness of a fixed coil on the first protrusion(34). The core(C) is spaced apart from an operation aperture by the permanent magnet. The core(C) winds an outer circumference of a core yoke(31).
