Abstract
The invention relates to a motor shaft sensor based on a graphene coating, comprising a graphene coating, a probe and an output circuit; the graphene coating is coated on the outer surface of the motor drive shaft; the probe includes a rigid metal detector and a built-in piezoelectric crystal , the rigid metal detector is fixedly connected to the stator of the motor through the support, one end of the rigid metal detector is in contact with the graphene coating, and the other end of the rigid metal detector is connected to the built-in piezoelectric crystal; the built-in piezoelectric crystal is used for Sensing the pressure of the rigid metal detector from the drive shaft of the motor under test, and outputting a corresponding charge signal; the output circuit is used to receive the charge signal, and convert the charge signal into an electrical signal for output. The motor shaft sensor based on the graphene coating has the advantages of simple structure, small size, light weight, high precision and reliable performance, and is suitable for high-precision motor testing, especially micro-motor testing.
Description
technical field [0001] The invention relates to the technical field of sensors, in particular to a graphene coating-based motor shaft sensor. Background technique [0002] Electric motors are widely used power equipment, and are indispensable basic products in various fields such as industrial automation, agricultural modernization, weapon equipment modernization, office automation, and family modernization. It will be further expanded. The performance of various motors varies greatly, and its performance parameters are difficult to clarify uniformly. Generally speaking, those used to drive machinery focus on the performance indicators during operation and starting, while the control micromotors focus on static and dynamic characteristic parameters. The description of various performances needs to measure the operating parameters of the motor, mainly including speed, torque, rotor position and so on. At present, the accurate measurement of these parameters is based on met...
