轧钢用直流电动机的使用及维护

Operation and Maintenance of DC Motor for Rolling Mill

分析了直流电动机在使用过程中常见的影响直流电机换向的几个因素。例如:直流电动机在安装时基础不牢固、直流电动机与所带机械对组不同心、换向器表面不清洁、换向器表面有划痕、换向器表面磨损严重、换向器表面产生严重的变形、电机的几何中性线位置发生变化等等,上述原因均将引起直流电动机换向性能变坏,针对每种情况提出了相应的解决方法,同时也提出了如何正确使用和维护直流电动机。

Several common factors having influence on Commutating of DC motor during operation of it.Fox example,infirm base of motor,uncoaliality of the motor and driven mechanism unit,dirt,scratched,and strongly worn and deformed surface of the commutator,and changed position of geometrical center line of motor,etc.All above reason can damage the performance of commutating of DC motor.Bejing quoted at each condition,relevant solutions are presented,and operation and maintenance of the motor are also presented.
