PURPOSE: A single-phase commutatorless motor is provided to easily assemble and dissemble a rotor consisting of a hob and a shaft to/from a frame. CONSTITUTION: A pipe type holder(2), which central portion is upwardly projected, is integrally formed with a frame(1). A stator core(4) for winding a coil(5) is seated on the frame. A shaft(6) is inserted into an inner diameter portion of the holder and is rotatably supported by a bearing. A hob(7) is coupled to a top end of the shaft and a coaxial magnet is attached to the inner circumference of the hob. A PCB(3) is attached to a bottom surface of the frame and has a hole for inserting the shaft. A cap(10) is attached under the frame to support the PCB, and a bottom end of the shaft passing through the holder is inserted into the cap.
