摘　　要：该文详细论述了异步起动的同步电动机起动过程中,投励转差率大小及投励方向对同步电动机正常起动的影响;首先通过分析同步电动机异步起动过程中,平均转矩和脉振转矩的变化规律,得到同步电动机投励时的转差率;其次通过分析起动过程中功角θ变化,而得到最佳投励方向。最后,提供了正确的选择方法和实施方案。This paper analyses the influence that the slip ratio and the direction of giving current has on the starting of synchronous motor during its asychronous starting;Frist through analyses rule of average torque and nervation torque of synchronous motor during its asychronous starting ,receives the slip ratio of giving current ;Second through analyses transformation of power-angle θ,receives the optimum direction of giving current. In the end, supplies the selecting method and project of them.
