Abstract:In view of the problems of the ferromagnetic material used in the traditional coupling device in the non-contact communication system, such as the wide temperature variability of the inductance, the limited application of a large number of vibration levels and the installation of the rotating end face, the new coupling device uses the printed copper wire group or the spiral disk made of multiple groups of wires to replace the traditional ferromagnetic material to form the communication medium, so as to realize the high-quality communication between the primary and secondary sides and ensure its engineering practicability. Combined with the example installation and temperature test verification, the device shows the characteristics of flexible installation and wide temperature adaptability.
