Abstract
In this paper, the moving-magnet segmented primary permanent magnet synchronous linear motor (SPPMSLM) with two primary stator units and one rotor is studied, the characteristics of magnetic field and force acting on the rotor during switching between two stator elements are analyzed. Firstly, the analytical expressions of the no-load air-gap magnetic field of SPPMSLM are derived by using the analytical method, and the results are verified by the finite element method, secondly, because the primary discontinuity in the structure of SPPMSLM results in the excessive magnetic resistance between the segments of the rotor, the size of the motor is simulated by the parameterized finite element method, the topology of adding auxiliary poles at both ends of the stator back iron is proposed, which is matched with the auxiliary teeth at the end of the primary stator unit, the effectiveness of the proposed structure in magnetic resistance reduction is evaluated by energy conversion method, which can provide some reference value for structure design and performance optimization of SPPMSLM.
