Abstract
The present disclosure provides a motor structure including a winding set, a rotor and a motor base. The rotor is driven by the winding set. The motor base includes a central portion, a surrounding portion, at least one connecting element and at least one limitation element. The winding set is disposed on the central portion. The surrounding portion is disposed around the central portion. The limitation element includes a first limitation part and a second limitation part disposed on the central portion and the surrounding portion, respectively. The connecting element is deformable and connected between the central portion and the surrounding portion. The connecting element includes a first supporting part and a second supporting part connected between a deformation part. The first supporting part, the second supporting part and the deformation part are cooperatively form a buffer zone between the first limitation part and the second limitation part.
