摘要
针对异步电机的传统启动方式会产生很大的冲击电流、冲击转矩及冲击力矩,对电网、电机及其机械设备带来严重影响,尤其对大功率电机危害尤为严重。该文介绍的电机软启动器以FPGA作控制器,并设计了硬件电路;在此基础上,完成了实验验证,达到了设计的预期效果,具有重要的推广价值。
Because the traditional starting method of asynchronous motor will have a great impact,shock and impact torque current torque,and efficiency is very low;thus,the motor and its load of power grid equipment brings the serious influence,especially for the large capacity motor,this is especially serious harm.Motor soft starter is introduced in this paper,using FPGA as the controller,and the design of the hardware circuit;on this basis,completed the experiment,to achieve the desired effect design,has important application value.
