A motor structure is disclosed. The motor structure comprises a stator and a rotor. Among these, the stator further comprises a coil seat defined by a bottom plate, a plurality of first teeth and a plurality of second teeth. A coil is formed in the coil seat. The first teeth formed around inner periphery of the bottom plate and have a first extending portion extending so as to constitute a reversed L shape. The second teeth formed around outer periphery of the bottom plate and have a second extending portion so as to constitute a reversed L shape. The rotor, coupled to the stator, further have a circular magnet formed above the coil seat, the first extending portion and the second extending portion. Each of the first and second extending portions further comprises a chamfer, a fillet, a clearance, a fold and different dimension.
