20090241719 | SIX-DEGREE-OF-FREEDOM PRECISION POSITIONING SYSTEM - In a six-degree-of-freedom precision positioning system, magnetic force and fluid buoyancy are used to levitate a platform, and the non-contact magnetic force between electromagnets and magnets forms a main driving force for the platform. Therefore, no friction is present in the system and no lubricating mechanism is needed for the system. Moreover, in the system, electric current is converted by electromagnets and magnets into a magnetic driving force without using any transmission gears. Therefore, the backlash phenomenon that is not easily controllable in the conventional servo positioning systems is avoided. The system has simplified structure without the need of complicated fabrication, and utilizes the properties of fluid to achieve low power consumption, high precision positioning, and fast response. | 10-01-2009 |
