This paper compares force measurements on a shielded coreless linear permanent magnet motor with 2-D models. A 2-D semianalytical modeling method is applied, which is based on Fourier modeling and includes force calculations. The semianalytical modeling correctly predicts the behavior found in the measurements, disregarding the saturation effects in the shield. The proposed semianalytical modeling method gives a good preliminary indication of the forces, which makes it a valuable modeling technique during design.
