Abstract： Aiming at the problems of large volume and high cost on traditional singleaxis servo drive， to meet the needs of servo drive with a compact structure in the industrial automation market， a dualaxis digital permanent magnet synchronous motor（PMSM） servo system was designed based on a single STM32F103 Two advanced control timers， three high speed AD， two quadrature encoders and other on chip resources were used Two IPMs were constructed as the parallel inverter Synchronous control algorithm was also designed in the programThe system is compact, and the experimental results show that the performance of this dual axis servo drive can meet the requiements in the application
