Abstract: Miniaturization represents a pivotal research focus that drives the advancement of servo motor technology. A dual-stator disk-type axial-flux permanent magnet synchronous motor was proposed that benefited the advantages of high torque density and flexible spatial design, resulting in the highly integrated motor designs and reduction of drive systems' volume. A dual-stator disk-type axial-flux permanent magnet synchronous motor with a rated power of 5. 4 kW and a rated speed of 3 000 r / min was designed, as well as the main electromagnetic performances were analyzed. Two approaches were introduced to reduce torque ripple including optimization of tooth-pole design parameter and asymmetric stator disk structure. The impact of the asymmetric stator disk structure on the structural strength of the rotor was investigated. The
feasibility of the motor and its key performance parameters were validated through experimentation.

Key words: transverse flux permanent magnet synchronous motor( TFPMSM), disk motor, torque ripple, servo motor
