Patent number: 7683518Abstract: 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 ?a 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.Type: GrantFiled: February 28, 2007Date of Patent: March 23, 2010Assignee: Panasonic CorporationInventors: Yuichi Yoshikawa, Kiyomi Kawamura, Hiroshi Murakami, Hideharu Hiwaki, Yasushi Kamada, Hiroki Sato

Patent number: 7622841Abstract: 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.Type: GrantFiled: May 31, 2007Date of Patent: November 24, 2009Assignee: Panasonic CorporationInventors: Yuichi Yoshikawa, Hiroki Sato, Yasushi Kamada, Hiroshi Murakami
