The pulse tube refrigerator is one of the most commonly used small-scale cryogenic refrigerators. The linear compressor driven by a linear motor is a key component of the pulse tube refrigerator. The two main types of linear motors used in pulse tube refrigerators were introduced,including various structures of the moving coil type and moving magnetic linear motors,as well as the characteristics of various types. The linear motor design,monitoring and operation were described. The development trend of the linear motor for pulse tube refrigerators was pointed out,which would provide reference for scientific researchers in this field.
