Abstract

PURPOSE: To make a rotation signal detection unit small-size by using the field magnetic flux of a motor as the energy source of the speed detection part.
CONSTITUTION: Disc 1 where concaves and convexes and convexes are cut on the outside circumference is connected to rotor field system magnet 2 into one body. Hall elements 101W103 are fixed to stator magnetic path material 3 through insulating materials 501W503 at a pitch of 120° and detect the magnetic flux of rotor field system magnet 2 on the course 300 passing through disc 1. The current supply quantity to Hall elements 101W103 is controlled according to the output of Hall elements to enlarge the output. From the output is Hall elements 101W103, signals corresponding to the rotation position and the rotation speed of the rotor are taken out.
