3D Characteristic Analysis of 3-Leg Linear Permanent Magnet Motor With Magnet Skew and Overhang Structure

This paper presents the 3-leg linear permanent magnet motor (TLPMM), which has a novel structure. It has an advantage of reducing the entire volume due to the attraction force cancellation. The TLPMM consists of stator and mover modules, simplifying the manufacturing process and maintenance. The TLP...
