Development of One Body Rotor for DVD Driving Motor |
| Abstract |
Recently, the efforts for the development of DVD concentrate on the high storage and multi-media. DVD has been manufactured by assembling many parts and it causes the vibration and noise. In this paper, one body rotor is proposed, which can make the nose and vibration be decreased. The injection mould for DVD rotor is designed by finite element analysis and the rotor is manufactured in the mould. The magnetic flux density is measured on the surface and it is compared with the design criteria. |
