Abstract: An armature includes a multi-phase armature coil and an armature core. The armature core includes a back yoke, a plurality of large-width teeth and a plurality of small-width teeth having a smaller circumferential width than the large-width teeth. The large-width teeth each radially protrude from the back yoke and are spaced from one another in a circumferential direction of the armature core. The large-width teeth have the armature coil concentratedly wound thereon. The small-width teeth each radially protrude from the back yoke and are spaced from one another in the circumferential direction of the armature core. The small-width teeth are arranged alternately with the large-width teeth in the circumferential direction of the armature core. Moreover, 1≤W1/W2≤2, where W1 is a radial width of the back yoke and W2 is the circumferential width of the small-width teeth.

Abstract: An electric rotating machine includes a power transmission mechanism and an armature. The power transmission mechanism is equipped with a first, a second, and a third rotor. The first rotor includes n soft-magnetic members. The second rotor includes k soft-magnetic members. Note that n and k are an integer more than one. The third rotor is made up of magnets whose number of pole pairs is m where m is an integer more than or equal to one. The armature faces the third rotor. The first, second, and third rotors are arranged so as to establish a magnetic coupling among them. The soft-magnetic members of the first and second rotors and the magnets of the third rotor meet a relation of 2m=|k±n|. This arrangement is capable of achieving the transmission of power regardless of electric energization of the armature.

Abstract: A double-stator includes outer and inner stators each having magnetic poles. Outer-stator and inner-stator windings are connected in series in phases, thereby generating winding magnetomotive force. Outer magnets and inner magnets of a rotor are arranged in a rotor core in the circumferential direction, the outer and inner magnets being alternated between a radially outward portion and a radially inward portion, at a pitch equal to that of the poles of the outer and inner stators so as to be magnetized so that a radially outer side thereof will serve as N poles or S poles and that a radially inner side thereof will serve as S poles or N poles. The rotor core includes outer poles formed between the outer magnets circumferentially adjacent to each other in the radially outward portion, and inner poles formed between the inner magnets circumferentially adjacent to each other in the radially inward portion.

Abstract: An AC excitation synchronous rotating electric machine includes a multi-phase coil, an armature core, an outer yoke core, a field-winding-less rotor and a controller. The armature core has the multi-phase coil wound thereon. The rotor is rotatably disposed so as to face the armature core and includes magnetic poles each having a facing portion and a magnetic reluctance portion. The facing portion is provided at one axial end of the magnetic pole so as to face the outer yoke core and allow magnetic flux to flow therebetween. The magnetic reluctance portion is provided at the other axial end of the magnetic pole to impede the magnetic flux from flowing therethrough. The controller controls supply of multi-phase alternating current to the multi-phase coil so that magnetomotive force generated in the armature core is applied to the magnetic poles, thereby causing the magnetic poles to operate as a DC field.

Abstract: In a double drive shaft motor, a stator and a field rotor are arranged at a radially outer side of a magnetic modulation rotor. The stator and the field rotor are arranged in series in an axial direction of the motor. This structure increases an amount of a winding coil of the stator and magnets in the field rotor, and an output torque of the motor. When a field magnetic flux passes through soft magnetic material members in the magnetic modulation rotor, because the generation and the reception of the magnetic flux can occur at a radially same side of the magnetic modulation rotor, this structure cancels an eddy current generated in the soft magnetic members and supporting members made of non-magnetic metal which tightly support the soft magnetic member. This structure provides a reduced axial size of the motor with high performance.

Abstract: A dual-rotor electric rotating machine includes a stator and first and second rotors that are arranged with the stator interposed therebetween. The stator includes a stator core, at least one stator winding and a stator core support. The at least one stator winding is formed of a plurality of electric conductor segments each of which is substantially U-shaped to have a base and a pair of end portions. The electric conductor segments are received in slots of the stator core so that the end portions of the electric conductor segments are located on the same side of the stator core as the stator core support and the bases of the electric conductor segments are located on the opposite side of the stator core to the stator core support. Each corresponding pair of the end portions of the electric conductor segments are electrically connected with each other.

Abstract: A rotor includes a rotor core and permanent magnets. The rotor core includes annular bodies that are stacked in a stacking direction and each formed of core segments arranged along a circumferential direction. The number of the core segments in each of the annular bodies is set based on k, where k is the number of magnetic poles formed by the permanent magnets. The rotor core has n through-holes, where n≧k. The rotor further includes n fixing members each of which extends in the stacking direction through one corresponding through-hole of the rotor core. Between each circumferentially adjacent pair of the core segments, there is formed a gap that is greater than a clearance provided between the through-holes of the rotor core and the fixing members. At least one of the annular bodies is circumferentially offset from another annular body by an integer multiple of one magnetic pole.
