An electromagnetic driving module, comprising:
- a base, having a groove;
- two first magnetic elements, arranged along a first reference line and disposed on two sides of the base;
- a wiring assembly, situated on a reference plane with the first reference line extended thereon, arranged adjacent to the two first magnetic elements and connected to the base, wherein the wiring assembly is configured to allow an electric current to pass therethrough;
- a reference element, disposed in the groove of the base;
- and
- a sensor element, arranged adjacent to the reference element and configured to detect the movement of the reference element to position the base;
- wherein the sensor element is disposed to face the reference element in a direction parallel to the reference plane, and the wring assembly is positioned between the reference element and the sensor element along the direction parallel to the reference plane.
