Claims (1)
ータに設けた磁気抵抗素子により検出して速度制
御を行うＦＧ機構を備え、外周面にＦＧ用磁極を
円周方向に交互に着磁した環状磁性部材のロータ
軸に直交する２つの端面にそれぞれ異なる単極を
着磁し、該磁極により発生する滋界により磁気抵
抗素子を検出磁界と直交する方向に磁気バイアス
したことを特徴とするＦＧモータ。 It is equipped with an FG mechanism that controls the speed by detecting a large number of FG magnetic poles provided on the outer circumferential surface of the rotor using a magnetic resistance element provided on the stator, and has an annular magnetic structure in which the FG magnetic poles are alternately magnetized in the circumferential direction on the outer circumferential surface of the rotor. An FG motor characterized in that two end faces of a member perpendicular to a rotor axis are magnetized with different single poles, and a magnetic field generated by the magnetic poles magnetically biases a magnetoresistive element in a direction perpendicular to a detected magnetic field.
