Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a self-charging integrated rotary machine speed sensor and a speed calculation method thereof. Background technique [0002] Traditional speed sensors include laser speed sensors, eddy current speed sensors, encoded speed sensors, etc., which have the following disadvantages: [0003] (1) Traditional speed sensors generally use wired power supply, which cannot realize automatic power supply and speed measurement; [0004] (2) The laser speed sensor requires a laser probe and a smooth reflective surface, which is not easy to install under harsh working conditions; [0005] (3) The eddy current speed sensor needs to open a keyway on the rotating shaft, and calculate the speed through the induction recording pulse time interval between the keyway and the eddy current probe. Opening the keyway of the shaft requires changing the design of the shaft system, which is not conducive to ...
