Detailed Description
The present invention will be described in detail with reference to specific examples.

All falling within the scope of the present invention.
As shown in fig. 1-2, an electromagnetic levitation repulsion linear motor includes: the housing and the holder protect the entire internal structure. The whole electromagnetic coil, the permanent magnet, the resistance spring and the push rod are fixed on the shell through the fixing screws.
In order to fix the electromagnetic coil, the coil fixing seat is adopted to limit the electromagnetic coil.
When not electrified, the push rod is contracted in the shell due to the mutual attraction of the permanent magnet and the electromagnetic coil.
Specifically, in one embodiment, the permanent magnet employs any one of: sintered ferrite, bonded ferrite, injection-molded ferrite.
After the power is switched on, the electromagnetic coil generates electromagnetic force and generates magnetic force repelling with the permanent magnet, so that the push rod is pushed to move upwards.
Specifically, in one embodiment, the electromagnetic coil is any one of: air core coil, ferrite coil, iron core coil, copper core coil.
The size and the direction of the electromagnetic force of the electromagnetic coil can be changed by adjusting the current size and the direction of the electromagnetic coil, so that accurate and controllable linear motion of the push rod is generated. A resistance spring between the housing and the push rod assists in resetting upon power failure.
The invention adopts the principle that magnetic opposite poles attract and like poles repel. The repulsion force of the electromagnet and the permanent magnet (or another electromagnet) is used as the power of the linear motion mechanism, and different electromagnet repulsion forces are generated by controlling different currents to push the push rod to move.
Specifically, in one variation, the repulsion force for the magnetic is the main motive force of the linear motor, thus enhancing or generating the same repulsion force, such as:
1. an electromagnet is arranged on the push rod;
2. increasing the number or size of electromagnets;
3. and adding a permanent magnet.
