提出了一种具有高力密度的新型齿轮齿的横通量管状直线机床。齿可以由用于管状线性开关磁阻或管状线性混合电机的硅钢片或永磁体形成。独特的改进齿形结构和短磁循环路径，可在减小电机重量和体积的情况下获得更大的推进力输出。基于有限元法的仿真验证了该机床设计的有效性。将所提出的电机与其他横向磁通线性电机进行了比较。结果表明，所设计的管状电机具有较好的输出性能和较高的力体积比。
A transverse-flux tubular linear machine with novel gear-shaped teeth for high force density is proposed. The teeth can be formed by silicon steel laminations or permanent magnets for a tubular linear switched reluctance or tubular linear hybrid motor. With the unique improved teeth structure and short magnetic circulation paths, larger propulsion force output can be obtained with reduced mover weight and volume. Simulation based on finite element method (FEM) verifies the validity of the proposed machine design. The proposed machines are compared with other transverse-flux linear machines. Results show that the proposed tubular motors exhibit better output performance with a higher force-to-volume ratio.
