The invention discloses a constant magnetic force preloading mechanism and a control method thereof. Comprising a mounting base, a high-precision motion platform, a sliding block combination, a magnetic device, a steel wire rope, a roller combination and a tension sensor, wherein the high-precision motion platform and the sliding block combination are arranged on the mounting base; the magnetic device is arranged on the sliding block combination; the steel wire rope is connected with the high-precision motion platform and the magnetic device; the steel wire rope is arranged on the roller combination, and the high-precision motion platform and the magnetic device are arranged on the two sides of the mounting base; when the high-precision motion platform performs acceleration and deceleration motion, the magnetic force of the magnetic device changes along with the change of the tension of the high-precision motion platform; the magnetic device can ensure that the magnetic force is consistent with the tensile force of the high-density motion platform to the greatest extent, and the positioning precision of the high-precision motion platform is effectively improved.
