电动机启动方法的分析和比较

Analysis and Comparison of Motor Starting Method

电动机的启动不仅需要具备较大的启动转矩,还要求启动电流小、操作简单、功率损耗小,通过对几种电机的启动方法进行比较,分析不同启动方法的工作原理和它们的优点和缺点,以及使用不同启动方法对电动机和电网系统其他设备产生的影响。

The motor starting not only needs larger starting torque, but also requires small starting current, simple operation, small power loss, the article compared several motor starting methods, analyzed the working principle of different starting methods and their advantages and shortcomings,and the affecting of different methods for starting motors to other equipment grid system.
