    摘要: Provided is a reactor that enables high inductance to be generated with stability in a wide current range, while minimizing noise, processing cost, and eddy-current loss. The reactor (D1) has the ratio (t/W) of the width (W) to the thickness (t) of a conductive member that composes an air-core coil configured to be 1 or less, and preferably, 1/10 or less. Furthermore, the reactor also has the absolute value of a value ((L1−L2)/L3) that has had: the difference (L1−L2) between; the space interval (L1) between an inner wall face of a first core member (3) and an inner wall face of a second core member (4), at the innermost circumference position of the air-core coil (1); and the space (L2) between the inner wall face of the first core member (3) and the inner wall face of the second core member (4), at the outermost circumference position of the air-core coil (1); divided by an average value (L3); configured to be 1/50 or less.

    摘要: This DC brushless motor (1) is provided with a stator (2) that has exciting coils (31, 32) and a rotor (4) that is positioned coaxially to the stator (2). The stator (2) has a quasi-E-shaped cross-section in the axial direction at the radius part; a plurality of protrusions (212, 222, 232) serving as magnetic poles are formed on the respective 3 parallel sections (211, 221, 231) of the E in the same number in the circumferential direction; and of the magnetic poles (212, 222, 232) formed at the 3 parallel sections (211, 221, 231) of the E, the top and the bottom magnetic poles (212, 232) are respectively positioned so as to be shifted in the opposite directions in the circumferential direction with respect to the center line of the middle magnetic pole (222). Changes in the magnetic resistance between the stator (2) and the rotor (4), which are caused by the flow of a magnetic flux generated around the exciting coils (31, 32), are utilized as a driving force. The DC brushless motor (1) configured in said manner exhibits excellent space efficiency at low cost and is less affected by temperature changes.
