中文摘要：
三相笼型异步电动机因集肤效应导致参数随转差率的改变而变化,采用机械特性实用表达式建立鼠笼式异步电动机启动特性模型,仿真结果与试验结果相差甚远。针对这一问题,利用转矩实用修正表达式绘制了启动特性曲线。实践证明,该曲线与试验所测曲线较为一致,从而验证了该方法的正确性和优越性。
英文摘要：
Because of the skin effect,the parameters of 3-phase squirrel cage asynchronous motor change complying with varying slip.The startup characteristic model is established by adopting mechanical characteristic practical expression,while the simulated result is quite different from the experimental result.For this case,with torque practical correction expression,the startup characteristic curve basically conforms to the curve obtained from the experiments.The correctness and superiority of the method are verified.
