Claim:
1. An anti-tilt electromagnetic motor, comprising: a frame comprising a first lateral sub-frame, a second lateral sub-frame, and a front sub-frame positioned between the first lateral sub-frame and the second lateral sub-frame; a support base, arranged movably relative to the frame along a main axis; a contact assembly disposed between the support base and a portion of the first lateral sub-frame that is adjacent to the front sub-frame and disposed between the support base and a portion of the second lateral sub-frame that is adjacent to the front sub-frame; a drive assembly configured to actuate a movement of the support base, wherein the driving assembly comprises a coil and a magnetic element, wherein one of the coil and the magnetic element is disposed on the support base, and the other one of the coil and the magnetic element is disposed corresponding to the one of the coil and the magnetic element by a distance, wherein a magnetic force generated by the coil relative to the magnetic element is greater than the weight of the support base; and an elastic assembly connecting the support base to the front sub-frame and configured to provide a pre-loading force so as to enable the contact assembly to be compressed by the frame and the support base simultaneously.
