求翻译：9-11item分别是650kw，6000kw，7600kw电机冷却器风机电机，因为该电机可以正反双向旋转，所以每台电机需要配备2台风机电机是什么意思？

9-11item are 650kw, 6000kw, 7600kw motor cooler fan motor, because the motor can be both positive and negative bi-directional rotation, so each motor with 2 typhoon electromechanical machine

Item 9 - 11, 6000, 650 kW kW kW motor cooler, 7600 blower motor, the motor can be both positive and negative because bi-directional rotation, so that each motor will be equipped with mechanical and electrical machine 2 typhoon

9-11item respectively is the 650kw,6000kw,7600kw electrical machinery chiller air blower electrical machinery, because this electrical machinery may pro and con bidirectional revolving, therefore each electrical machinery needs to provide 2 typhoons mechanical and electrical machine

9-11item namely 650kw,6000kw,7600kw motor cooling fan motor, since the motors can be bi-directional rotating positive and negative, so each of the motors required 2 Typhoon motor
