    摘要： A stator core for a concentrated winding type brushless DC motor that has a plurality of spaced teeth extending inwardly of the core outer diameter to a core inner diameter to define slots between two adjacent teeth for a winding. Each tooth has right and left distal ends projecting in opposite directions transverse to the tooth with the opposite distal ends of two adjacent teeth each being linear and defining an aperture into a slot between the two teeth. The distal end of each tooth also has an angled edge at the side facing the core outer diameter so that the distal end is wider at the aperture than at the point where the distal end extends from the tooth. Also, there is a distance T between a line connnecting the end points of the right and left distal ends of a tooth facing the core outer diameter at the aperture defined by each said distal end and a tangent line at an inner core diameter of the tooth and such that T≧0.

    摘要： It is an object to provide a rotor of an electric motor in which an adverse influence due to through holes for caulking and fixing is reduced, and moreover, the number of parts is small and an assembling operation is simple, so that high characteristics can be obtained, which is constructed by: a rotor core constructed by laminating a plurality of iron plates for the rotor; at least two slots which are formed in the rotor core along the axial direction of a rotation axis; and at least four flat permanent magnets which are inserted to the slots, and in which as the permanent magnets, each pair of magnets which face each other between adjacent magnetic poles are arranged in parallel at predetermined intervals so as to sandwich a normal line of the rotor. In addition, the permanent magnet rotor is made to satisfy the condition: L/D being between 0.3 and 1.2 and t/I being between 0.02 and 0.2, wherein L is the thickness of the laminations, D is the diameter of the rotor core, t is the thickness of the permanent magnets, and I is the length of the permanent magnets.
