摘要： A low speed alternating current motor having motor shaft speeds of about (300) is provided, and such motor has application in numerous industries and devices, such as, for example, in top drive drilling systems. Because of the low shaft speed, mechanical speed reduction equipment may not be necessary. In addition, the motor shaft may be hollow to facilitate the flow of fluid, such as, for example, drilling mud.
摘要翻译： 提供具有大约（300）的电机轴转速的低速交流电动机，并且这种电动机可以应用于许多行业和装置中，例如在顶部驱动钻井系统中。 由于轴转速低，机械减速设备可能不是必需的。 此外，马达轴可以是中空的，以便于流体的流动，例如钻井泥浆。
