    摘要: A motor includes a stator formed of a stator iron-core having salient pole iron-cores and windings, and a rotor having a rotor iron-core in which permanent magnets are buried. A magnetic pole centerline connecting a rotary center of the rotor to a magnetic pole center crosses an external shape of the rotor iron-core at end point X, and the magnetic-pole boundary line connecting the rotary center to a magnetic pole boundary point crosses the external shape of the rotor iron-core at end point Z. A straight line angled at a given angle θa from the magnetic pole centerline has end point A. Then a sectional view of the rotor iron-core shows an arc drawn between the end points X and A, and the arc's center is the rotary center. The end points A and Z are connected by one or more than one straight lines in series.

    摘要: A motor includes a stator and a rotor. The stator is configured by winding a coil around a stator core which includes a salient-pole core. The rotor has a rotor core made by laminating thin and highly permeable iron sheets. The rotor core has multiple permanent magnet embedding holes, and a permanent magnet is embedded in each of the permanent magnet embedding holes. A cross-section of the permanent magnet is a rectangle with a long side in a rotating direction and a short side perpendicular to the long side. A cross section of the permanent magnet embedding hole is formed by an embedding hole's long side corresponding to the long side and an embedding hole's short side corresponding to the short side. The embedding hole's short side has a first protrusion and a flat portion. The embedding hole's long side to an inner diameter side has a second protrusion on its both ends.

    摘要: The invention makes it possible to perform effective A/D conversion on pixel signals read from a pixel array part, to achieve a reduction in power consumption and reductions in the size and the price of an image pickup device as well as simplification of the construction of the device, and to realize a high-quality image output. The device includes an pixel array part having a plurality of unit pixels, a CDS (correlated double sampling) circuit, and an A/D converter. A pixel signal read from a pixel array part via a signal line is subjected to CDS processing (noise elimination processing) in the CDS circuit, and then this pixel signal is inputted into the A/D converter which performs A/D conversion on the pixel signal. The A/D converter includes a ΔΣ modulator and a digital filter to perform highly accurate A/D conversion. The invention can also be applied to a construction in which an A/D converter is provided at the front stage of the CDS circuit.
