摘要： To downsize a bearing assembly with a rotation detection device, a magnetic generating element (2) having a directionality about a rotation axis O is provided on an inner race (21) side of the bearing assembly (20). A rotation sensor (3) capable of detecting a magnetism of the magnetic generating element (2) and outputting information descriptive of rotation or angle is fitted to an outer race (22) side in alignment with a bearing axis. The magnetic generating element (2) is fixed to a fixing member, for example, a rotary shaft (10) that is fixed to an inner diametric side of the inner race (21) of the bearing assembly (20).

摘要： To provide a compact bearing assembly equipped with a rotation sensor capable of detecting not only pulse signals for detecting the number of revolution, but also a home position signal, the bearing assembly equipped with the rotation sensor includes a rotatable member (2) and a non-rotatable member (3) with rolling elements (4) interposed between the rotatable and non-rotatable members (2) and (3) to permit the rotatable member (2) to be rotatable relative to the non-rotatable member (3). The rotatable member (2) is provided with a magnetic encoder (7) and the non-rotatable member (3) is provided with magnetic sensors (8A) to (8C). The magnetic encoder (7) includes first and second to-be-detected elements (7A) and (7B) each having a plurality of equally spaced, opposite magnetic poles defined therein so as to alternate with each other in a direction circumferentially thereof. The first to-be-detected element also has a magnetic characteristic disturbing element (15) provided at a predetermined site on a circumference of the magnetic encoder (7) for agitating a periodicity of the opposite magnetic poles. The two magnetic sensors (8A) and (8B) for detecting the first to-be-detected element (7A) are spaced in a circumferential direction a distance greater than a circumferentially extending width of the disturbing element (15), and are so positioned as to be held in substantially phase-matched relation with a cycle of repetition of the opposite magnetic poles.
