Abstract: The method of integrating two sets of stator cores in the same armature makes the structure of transverse⁃flux permanent magnet (PM) linear motor with double Ω⁃hoop stator more compact, and space utilization, efficiency and power density high. On the basis of analyzing the new transverse flux permanent magnet linear motor with double Ω⁃hoop stator, two kinds of cylindrical transverse flux permanent magnet motors with double Ω?hoop stator transverse are designed. The finite element analysis (FEA) method is used to carry out the comparative analysis for the flux density waveform in the air gap, back electromotive force (EMF), flux linkage and electromagnetic torque of two kinds of motors. The results show that the three⁃phase structure motor has compact structure, and is applicable to the strictly⁃limited motor volume and high torque occasions; the single⁃phase structure motor is ideal for the magnetic flux density distribution, counter EMF, flux linkage parameter waveform, and is a better choice in high⁃precision occasion.
