潜液式液化天然气(liquefied natural gas，LNG)泵低温电机(简称LNG泵低温电机)是LNG泵的核心部件。为了便于LNG泵低温电机的研制，该文对该类型电机的发展情况及相关技术进行了综述。文中详细调研了已存在的几种类型的低温电机的特点及其发展现状。根据备选电机的特点和LNG泵的应用环境，总结了LNG泵低温电机关键技术及发展现状，提出了亟待研究的技术问题，设计了LNG泵样机的试验平台及相关测试原则。根据LNG泵的应用环境，该文提出的LNG泵低温电机的选用原则指出，低温异步电机和低温永磁同步电机适合作为LNG泵的备选电机，并认为在技术不成熟的初期阶段，低温异步电机更为适合作为LNG泵低温电机进行研制；随着技术的积累，LNG泵低温永磁电机将逐步研制成功。这些工作为LNG泵低温电机的研制提供参考。

As the cryogenic electrical motor is the key component of the submerged liquid natural gas (LNG) pump, this paper summarized the development of cryogenic electrical motors to promote the research of the cryogenic electrical motor for the LNG pump. All kinds of the existing cryogenic electrical motors was presented and analyzed in this paper. And the key technologies and status were summarized so that the technical problems of the cryogenic electrical motor for the LNG pump were proposed. Based on the selection principle of the cryogenic electrical motor for the LNG pump, cryogenic induction motors and cryogenic permanent magnet synchronous motors are suitable for the LNG pump. And the cryogenic induction motor is more suitable for the LNG pump at the exploratory stage. With the developing of the cryogenic induction motor, the cryogenic permanent magnet synchronous motor can be developed further. The work lays the foundation for the development of the cryogenic electrical motor for the LNG pump.
