摘要:
A rotary electrical machine has a mechanism capable of varying an output characteristic, without increasing mechanical loss, or without consuming the electric power that does not contribute to increasing torque. The rotary electrical machine has a rotor with N pole and S pole magnets alternately and fixedly disposed thereon. An end surface, (which opposes the rotor), of each of a plurality of first teeth positioned on a first stator section is broader than that of the opposite surface thereof, and a winding is wound around a portion between both of the end surfaces. A second stator section has second teeth, corresponding the number of the first teeth, and which has no winding. The second teeth are disposed to oppose the end surfaces of the respective first teeth, and each second tooth is reciprocally movable between a reference position at which the second tooth directly opposes the respective first tooth and a maximum movable position located at the right center position between the respective end surfaces. At the reference position, a strong magnetic flux flows into the entire first tooth from each magnet. At the maximum movable position, a weak magnetic flux flows over the end surface of each first tooth. A middle amount of the magnetic flux flow occurs at a middle moved position.
