An anti-tilt electromagnetic motor is provided, including a frame, a support base, a contact assembly, a drive assembly, and an elastic assembly. The support base is arranged movably relative to the frame along an axis. The contact assembly is disposed between the frame and the support base and directly contacts the frame and the support base. The drive assembly is configured to drive the support base to move. The elastic assembly is configured to provide a pre-loading force so as to enable the contact assembly to be compressed by the frame and the support base.


An electromagnetic driving device is provided, which includes a movable member, a stationary member, a driving magnet, a driving coil, a conductive layer, and an external terminal. The movable member and the stationary member are arranged separate from each other along a main axis. The driving magnet is positioned on the movable member. The driving coils are arranged corresponding to the driving magnet and are disposed in the stationary member. The conductive layer is electrically connected to the driving coils and is disposed in the stationary member. The external terminal is exposed by the fixed member and electrically connected to the conductive layer. The thickness of the external terminal is different from the thickness of the conductive layer.
