A hub that supports a disc-shaped recording medium that rotates together with the rotating shaft, a rotor that has a permanent magnet and rotates integrally with the rotating shaft, and a coil that is disposed on the outer circumferential side of the rotor. An electric motor comprising a stator that is wound and generates rotational force on the rotor through magnetic action with the permanent magnet, characterized in that the hub and the rotor are constructed as an integral rotating body. . The brief description of the drawing has been amended as follows. The statement "and Figure 4 are respectively" on page 7, line 20 of the specification is amended to read "ha". The description of "Figures 5 and 6" in the first line of page 8 of the specification is amended to read "Figures 4 and 5."

Claims

[Scope of utility model registration request]

a rotating shaft rotatably supported by a bearing;
A hub that supports a disc-shaped recording medium that rotates together with the rotating shaft, a rotor that has a permanent magnet and rotates integrally with the rotating shaft, and a magnetic interaction between the coil and the permanent magnet. and a stator for generating rotational force in the rotor, wherein the hub and the rotor are configured as an integral rotating body.
