Abstract

PURPOSE: To secure the assured detection for the change of the forward/backward turns of the shaft through a simple constitution by forming the element to be detected to the shaft plus three units of contactless-type detectors to detect the approach of the detection element.
CONSTITUTION: The detection element like groove 1a or the like is formed to shaft 1 of the rotary electric machine or the like, and medium, higher and lower contactless detectors 2W4 are provided around shaft 1. Thus the forward or backward turn is detected for shaft 1 by detecting the front and back parts of the output of detectors 3 and 4 against detector 2.
