    Abstract For the selection of large capacity water pump motor, capacity of the motor is calculated according to the technical data of the pump station; voltage class of the motor is determined through economical comparison of the cost for distributing cables and the line loss; staring mode of the motor is decided by calculating the relative value of the voltage at the bus and the terminal of motor.

    Key words Pump station Water pump motor selection Voltage class Starting mode of motor

 

    摘 要 大容量水泵电机的选择，需根据泵站的工艺资料计算电机容量；对配线电缆的造价、线损作经济比较，以确定电机的电压等级；计算电机启动时母线及电机端子处的电压相对值，以确定电机启动方式。
