摘要
将牵引风机常温的试验结果作为基础数据,通过理论换算得出-40℃下的牵引风机的启动时间,从而推导出牵引风机的启动转矩特性曲线,并将其与电机启动转矩特性曲线进行对比,结果表明电机提供的转矩在整个启动过程中都满足牵引风机需求。
Taking the test results of traction fan at room temperature as the basic data, the start time of traction fan at-40 ℃ is obtained by theoretical conversion. The starting torque characteristic curve of traction fan is deduced and compared with the starting torque characteristic curve of motor. The results show that the torque provided by the motor meets the needs of the traction fan in the whole starting process.
