摘　　要：在电机控制器的使用过程中,经常会由于电机控制器本身的过热保护,导致电动叉车不能按时按量的完成工作,特别是在环境温度较高的时候更是如此,从而严重影响了工作进度,为此,通过对电机控制器的重新设计改进,以及其影响散热的主要因素进行考察,最终验证电路板铜箔厚度才是影响电机控制器散热的最主要因素。Motor controllers often stops working because its temperature is too high to reach its temperature of protection, therefore, the work of electric forklift can not be completed as scheduled, especially in the environment of high temperature. The progress of work is seriously affected. The most important factor of radiation has been found after redesigning its motor controller. Result of the experiment shows that the most important factor of radiation is PCB board thickness of cooper foil.
