Single liquid drop support based external magnetic field driven micro rotating platform, driving method and driving apparatus for micro rotating platform

The invention provides a single liquid drop support based external magnetic field driven micro rotating platform, a driving method and a driving apparatus for the micro rotating platform, relates to the field of the micro rotating platform, and aims to solve the problems that the existing micro bearing supported and micro motor driven micro platform generates friction in motor transmission; the apparatus is complex and difficult to realize accurate and accurate system assembling and difficult to realize further microminiaturization. According to the micro rotating platform provided by the invention, the capillary force between the liquid drop and the micro platform is utilized to enable the micro platform to be floated on the liquid drop surface; three orthogonally-placed Helmholtz coil pairs are adopted to generate a uniform rotating magnetic field to realize the rotation movement of the micro platform; the rotating speed of the micro rotating platform can be changed by changing the rotating frequency of the
