The invention relates to the technical field of linear motors, and discloses a magnetic field isolation device for a linear motor. A linear motor stator is installed on a base; magnetic liquid is arranged in a liquid tank; a transmission body connected with a rotor of the linear motor is immersed in the magnetic liquid; the linear motor is covered with a sealing half shell, a pressing plate assembly is arranged on the unclosed side of the sealing half shell and clamped into the liquid groove in the movement direction of the transmission body, and the lowest position of the pressing plate assembly is lower than the liquid level of the magnetic liquid. One end of the connecting plate is fixed on the substrate, and the other end is immersed in the magnetic liquid. The substrate, the sealing half shell, the pressing plate assembly, the connecting plate and the magnetic liquid can all conduct magnetism, magnetic lines can form a closed enveloping space, and therefore the magnetic field sealing effect is achieved.
