摘要： A rotating electric machine includes a stator and a rotor. The rotor includes: a field core having at least one boss portion, a pair of disc portions and a plurality of claw-shaped magnetic pole portions; a field coil arranged between the at least one boss portion and the claw-shaped magnetic pole portions; a plurality of permanent magnets each of which is arranged between one circumferentially-adjacent pair of the claw-shaped magnetic pole portions; and a ring-shaped fixing member fixed to radially inner parts of the claw-shaped magnetic pole portions to support the claw-shaped magnetic pole portions from the radially inner side. Moreover, a d-axis magnetic circuit and a magnet magnetic circuit are at least partially coincident with each other to share a common circuit portion. When field current is supplied to the field coil, the permeance of the d-axis magnetic circuit is lower than the permeance of a q-axis magnetic circuit.

摘要： A rotor for a rotary electric machine, the rotor including first and second pole pieces each having a respective magnetic hub arranged for rotation about an axis along which they are spaced. Pluralities of magnetic first and second pole fingers are spaced from each other and extend between the hubs. Each pole finger has a proximal end connected to its respective hub, and an axially opposite distal end. The first and second pole fingers circumferentially alternate about the axis, and each pole finger has a respective radially inner surface defining a cavity that extends axially from the distal end to a cavity terminus. Relative to each pole finger, at a respective axial position between the distal end and the cavity terminus the radial distance between the axis and the radially inner surface is substantially greater inside of the cavity than outside of the cavity.

摘要： A rotor includes a first rotor core, a second rotor core, a permanent magnet and a resin layer. The first rotor core includes a first core base and first claw-shaped magnetic poles arranged at equal intervals on a peripheral portion of the first core base. The second rotor core includes a second core base and second claw-shaped magnetic poles arranged at equal intervals on a peripheral portion of the second core base. The first rotor core and the second rotor core are combined with each other so that the first and second core bases are opposed to each other and the first and second claw-shaped magnetic poles are alternately arranged in the circumferential direction of the rotor. The permanent magnet includes at least a main field magnet. The main field magnet is located between the first and second core bases in the axial direction, and is magnetized in the axial direction. The main field magnet causes the first claw-shaped magnetic poles to function as first magnetic poles, and causes the second claw-shaped magnetic poles to function as second magnetic poles. The resin layer covers at least a portion of a surface of the permanent magnet.

摘要： A motor includes a rotor and a stator. The rotor includes a first rotor core including a plurality of first claw-like magnetic poles, a second rotor core including a plurality of second claw-like magnetic poles, and a magnetic field magnet arranged between the first and second rotor cores. The first and second claw-like magnetic poles are alternately arranged in a circumferential direction. The magnetic field magnet causes the first and second claw-like magnetic poles to function as magnetic poles different from each other. The stator includes a first stator core including a plurality of first claw-like magnetic poles, a second stator core including a plurality of second claw-like magnetic poles, and a coil section arranged between the first and second stator cores. The stator is configured to cause the first and second claw-like magnetic poles of the stator to function as magnetic poles different from each other and switch polarities of the magnetic poles on the basis of energization to the coil section. At least ones of the claw-like magnetic poles of the rotor and the claw-like magnetic poles of the stator are formed in a shape in which circumferential centers of distal end portions are shifted in the circumferential direction with respect to circumferential centers of proximal end portions.

摘要： The invention relates to a rotor for a rotating electrical machine, comprising: a central shaft, an annular core coaxial to the shaft, a winding extending radially around the core, a first claw-pole and a second claw-pole arranged axially on each side of the core and the winding. Each claw-pole of the rotor comprises a plurality of triangular teeth having a base that is tangent to the pole wheel and comprising a first side, denoted a, and a second side, denoted b. The ratio of 1-a/b is between 0 and 0.5, or 0 and −0.5. The tip of the teeth of one of the claw-poles is equidistant between the ends of the bases adjacent to the tip of the teeth of the other claw-pole.
