In order to solve the problem of traditional high-voltage disconnector mechanism jamming and improve the thrust of the drive mechanism, a direct-drive magnetic field modulation transverse flux motor (MFM-TFM) is proposed in this paper. First, the three-dimensional structure of MFM-TFM is introduced. The expression of air gap flux density is derived according to the permeability method. The air gap flux density of the lower air gap dominated by the sixth harmonic is modulated into the air gap flux density of the upper air gap dominated by the fifth harmonic. The increase in the amplitude of low-order harmonics can increase the average thrust. Secondly, the upper and lower air gap widths, permanent magnets, iron cores, pole shoes and modulators are optimized. The optimized motor has good no-load back EMF and current waveform sinusoidality. Through core lamination, the loss of the transverse flux motor is effectively reduced. The rated average thrust of the motor reaches 612.54 N. Finally, the prototype was manufactured and the experimental test platform was built. The thrust and back EMF were measured and compared with the experimental values to verify the rationality of the proposed topology and the accuracy of the calculated results.
