Abstract
PURPOSE: To simplify constitution and to miniaturize this device, by miniaturizing a motor by unifying a rotor location detecting portion and a speed detecting portion while using the detecting portions as a double purpose for detecting the field system magnetic flux of a motor body.
CONSTITUTION: This device simultanesously detects the locations and speed of a rotor by means of a single detecting element, and uses magnetic flux as physical quantity to be detected, and matter that decides a pitch of rotor locations for detecting rotor locations, the first pitch, is a magnetic attaching magnetic pole pitch of the rotor, and the first variation element changing magnetic flux for deciding the locations is the N.S magnetic pole itself of the rotor. The second variation element for deciding a pitch of locations for detecting speed, the second pitch, is uneven wave-forms mounted to an outer circumference of a disc 1 fixed to a pivot or a side-wall of a rotor mganet. When magnetic flux changes containing the signals of two pitches by means of these two variation elements, the change is detected by means of the detecting element containing a magnetic core 51.
