SHAFT POSITION DETECTION DEVICE AND MAGNETIC LEVITATION MOTOR

摘要

A shaft position detection device and magnetic levitation motor, comprising: an eddy current displacement sensor probe (201) and an integrated proximitor (202) connected thereto, wherein the eddy current displacement sensor probe (201) comprises ten or more eddy current displacement sensor probe heads (2011), and two or more of the eddy current displacement sensor probe heads (2011) are provided to sense each of five degrees of freedom of a magnetic levitation motor shaft. The embodiments of the invention can efficiently save a space and facilitate device integration.
