Synchronous-driven positioning platform

Abstract

The invention discloses a synchronous-driven positioning platform which comprises a base, a motion platform and a driving motor. The driving motor can be of a movable ring type or a movable magnet type. A motor rotor and a motor stator are arranged symmetrical with the motion platform serving as the center. A left coil and a right coil are symmetrically arranged and respectively comprise a winding A, a winding B and a winding C. The winding A1, the winding B1 and the winding C1 of the left coil and the winding A2, the winding B2 and the winding C2 of the right coil correspond and are correspondingly connected in parallel, the number of parallel-connection branch circuits is two, a winding for the driving motor is formed and electrically connected to a driver, and therefore the problem that in the prior art, positioning platforms can not move synchronously is effectively solved. The synchronous running of the positioning platform is achieved through driving of the driving motor, the phenomena that torsion errors happen to the positioning platform and the positioning platform is stuck are avoided, positioning accuracy of the positioning platform is effectively improved, and production cost and use cost are reduced.
