The invention discloses an air floatation motion platform. The air floatation motion platform comprises a base; a first
linear motor, which is arranged on the base; a second
linear motor, which is arranged on the base, is opposite to the first
linear motor, and is separated from the first linear motor; a moving device, which is arranged between the first linear motor and the second linear motor and is connected with a rotor of the first linear motor and a rotor of the second linear motor; a first guide rail, which extends in the length direction of a
stator of the first linear motor; a first air floatation device, which forms air floatation between the first air floatation device and the first guide rail; a second guide rail, which extends in the length direction of a
stator of the secondlinear motor; a second air floatation device, which forms air floatation between the second air floatation device and the second guide rail; a first
magnetic levitation assembly, which forms a magnetic preload between the first
magnetic levitation assembly and the first guide rail; and a second
magnetic levitation assembly, which forms a magnetic preload between the second magnetic
levitation assembly and the second guide rail. Compared with the prior art, the air floatation rigidity is improved, the dynamic performance is good, the requirement for installation and adjustment is low, the structure is compact, and
engineering implementation can be achieved.
