The invention discloses a steering engine directly driven by piezoelectric motors, and belongs to the field of steering engines. The invention aims to solve the problems that a conventional steering engine is complex in structure and needs a decelerator during driving. The steering engine directly driven by piezoelectric motors, which is disclosed by the invention, comprises four motor sets, four groups of clamps, and a base, wherein the clamps are fixed on the base, and the motor sets are clamped by utilizing the clamps. The motor sets, namely piezoelectric motor driving feet, are utilized to directly drive a steering engine shaft, and an intermediate decelerating mechanism is not needed; the steering engine is small in size, light in weight and simple in structure; besides, the positioning precision of the piezoelectric motors can be accurate to microns, even nanometers; besides, the piezoelectric motors work through the inverse piezoelectric effect of piezoelectric materials, electromagnetic induction is not involved, and coils are not used in the structure of the steering engine, so that electromagnetic interference cannot be generated, and the steering engine cannot be influenced by external electromagnetic interference. The steering engine disclosed by the invention is suitable for the field of steering engines.
