Abstract

In this paper, the thrust density and thrust fluctuation of tubular C-core modular linear permanent magnet synchronous motor (TC-core MLPMSM) are optimized. In this paper, the characteristics of magnetic density distribution in the core of a tubular linear motor are analyzed. Based on the analysis, this paper proposes that trapezoidal stator slot will lead to a much larger thrust density than rectangular stator slot under the same volume and magnetic and electric load. Aiming at the problem of large force fluctuation in linear motor, modular structure is adopted and the detent force and thrust fluctuation are reduced. 2D finite element method (FEM) results are obtained to verify validity of the methods. Results show that the thrust density increases and the force fluctuation decreases after optimizations in TC-core MLPMSM.
