摘　　要：针对目前市场上主流人工心肺机中泵送血液的驱动装置存在结构复杂、体积较大、易对复杂手术环境造成干扰等问题,通过借鉴永磁无刷直流电动机设计原理和相关经验公式,根据市场上主流血泵结构设计了一款结构简单、体积小的小型平面回转驱动器。为实现高转速泵血需求,对已设计的定子结构,进行多组定子绕组匝数和励磁电流的单一变量实验测试,探究绕组匝数和励磁电流大小对运行转速的影响。结果表明:小型平面回转驱动器运行转速随绕组匝数或励磁电流的增大而增大,且运行转速与绕组匝数、励磁电流之间满足一定的函数关系。In view of the problems existing in the driving device of pumping blood in the mainstream artificial cardiopulmonary machine in the market at present,the structure is complex,the volume is large,and the complicated operation environment is easily disturbed.Based on the design principle and relevant experience formula of permanent magnet brushless DC motor,a small plane rotary driver with simple structure and small volume was designed according to the structure of mainstream blood pump in the market.In order to realize the blood demand of high speed pump,the single variable test of the number of turns and excitation current of stator windings has been carried out on the designed stator structure,and the influence of the number of turns and the magnitude of excitation current on the running speed has been explored.The results show that the running speed of the small planar rotary actuator increases with the increase of winding turns or excitation current,and the running speed satisfies a certain functional relationship with the number of winding turns and the excitation current.
