EDW—2L型和EDW—450—L型采煤机是装有电牵引部采煤机。其中,EDW—450—L重型采煤机装备有一台450kW中枢电机,驱动两个滚筒。两个电牵引部中的每个牵引部分别用一台25kW直流分激水冷电机驱动。一、驱动装置采煤机电机均装在机体中,作为整个采煤机的动力,但也可以单独驱动截割部。在后一种情况下,为了牵引采煤机和一些辅助装置,装有附加的驱动电机。采煤机电机是普通的水冷电机。水冷电机的主要优点是体积小,结构坚固,操作中无需清理,过载能
EDW-2L and EDW-450-L Shearer is equipped with electric traction shearer. Among them, EDW-450-L shearer is equipped with a 450kW hub motor that drives two rollers. Each of the two electric traction units is driven by a 25kW DC sub-cooling water-cooled motor. First, the drive Shearer motor are installed in the body, as a whole Shearer power, but can also be driven separately cutting. In the latter case, an additional drive motor is provided for towing the shearer and some auxiliary equipment. Shearer motor is a common water-cooled motor. The main advantages of water-cooled motors are small size, rugged construction, no need to clean up in operation, overload
