The invention discloses a method for separating a rotor and a main shaft of a shaft-penetrating permanent magnet motor in a diesel engine main shaft jacking test, and solves the problem that the test accuracy is influenced by how to avoid the generation of magnetic pulling force in the main shaft jacking test of the shaft-penetrating permanent magnet motor. When a jacking test is carried out on the diesel engine main shaft, a bolt for fixedly connecting the rotor bracket and a flange plate on the right side of the main shaft is detached, the rotor bracket and a magnetic yoke magnetic pole on the rotor bracket are moved leftwards, so that the rotor bracket is separated from the main shaft, and the rotor bracket separated from the main shaft, the magnetic yoke on the rotor bracket and a motor base are connected together through a T-shaped or L-shaped gasket; and the gap between the rotor and the stator of the motor is kept fixed by the thickness of the T-shaped or L-shaped gasket, so that the annular gap betwee
