ABSTRACT:
A stator structure of a motor. The stator structure has a base including a main body and a plurality of protrusions extending from the main body. A stator part has a plurality of magnetic-pole portions, wherein each protrusion is positioned in a gap between every two adjacent magnetic-pole portions when the stator part is disposed on the base, and a coil wound around the stator part. The outer circumference of the main body of the base includes a plurality of circular arcs with different radii, so as to provide a function of attaining bias when the motor is driven to start and preventing reduced rotational efficiency of the motor.
