The invention discloses a micro-motion platform for improving the resolution of a linear motor based on a flexible inclined beam. The micro-motion platform is provided with a base, six inclined beam components, two transition plates, an input plate, an output plate and two guide beam components. An output rod is mounted on the output plate of the micro-motion platform, and an output shaft of the linear motor is connected with the input plate of the micro-motion platform so as to apply the drive force to the micro-motion platform. The micro-motion platform disclosed by the invention has the functions of a two-level speed reducer in the same plane, improves the resolution of the linear motor by use of the motion reducing principle, and overcomes the shortcoming of lower resolution of the linear motor.
