| Abstract: | The torque ripple directly influences the servo performance of permanent magnet AC servo motor, and influences the precision of machining. This paper researched deeply on the torque ripple of permanent magnet AC servo motor with surface-mounted rotor, calculated and analyzed the influence of end thickness of permanent-magnet choosing and pole-slot matching on the torque ripple. After verification, the calculation results approach to the experimental values. |
