Abstract

A two-dimensional motor and a servo valve are provided. The two-dimensional motor includes a stator and a rotator arranged coaxially. The stator is enclosed in the rotor. The stator and the rotor are spaced along a radial direction of the rotor. A size of the stator along an axial direction is greater than a size of the rotor along the axial direction. The rotor is, without bearing support, directly connected to an external mechanism. The rotor is swung at a predetermined angle, such that the external mechanism can drive the rotor to move along an axial direction of the rotor relative to the stator.
