摘要： A tooth of a stator has a tapered shape in which a tooth width decreases toward a distal end portion thereof. A winding is formed of an edgewise winding wound around the tooth in a row. The winding is supplied with power so that a terminal on a base portion side of the tooth may have a higher voltage than that of a terminal on the distal end portion side thereof. A tooth width Th of the base portion is set within the range of Tmin

摘要： One end of each of phase conductors wound around a stator core in a wave winding arrangement is connected to a positive electrode terminal of a DC power supply through a first positive electrode side switch and is connected to a negative electrode terminal of the DC power supply through a second negative electrode side switch. The other end of the phase conductor is connected to the negative electrode terminal of the DC power supply through a first negative electrode side switch and is connected to the positive electrode terminal of the DC power supply through a second positive electrode side switch. The first positive electrode side switch, the second negative electrode side switch, the first negative electrode side switch, and the second positive electrode side switch are controlled by a controller, whereby amplitude and phase of current passing through each of the phase conductors are individually controlled.

摘要： Given a first intersection point of the surface of a rotor and a straight line that joins a central point of a permanent magnet on a stator side and a tooth tip section closest to the central point of the permanent magnet on the stator side, a flange is formed outward of an arc having, as the radius thereof, a distance from a second intersection point of the inner peripheral face of the stator and a straight line that joins the rotation axis of the rotor and the first intersection point, up to the tooth tip section.

摘要： Provided are: a synchronous machine having permanent magnets as a field system; a stress estimator that estimates stress acting on the permanent magnets; and a first magnet temperature corrector that calculates an amount of demagnetization due to stress of armature interlinkage magnetic flux on the basis of the estimated stress, estimates an amount of demagnetization due to stress of the armature interlinkage magnetic flux on the basis of the rotor position of the synchronous machine, a current command and a voltage command, and the amount of demagnetization due to stress of the armature interlinkage magnetic flux; and outputs a permanent magnet temperature estimated value after correction, having factored therein the amount of demagnetization due to stress of the armature interlinkage magnetic flux from the estimated armature interlinkage magnetic flux.

摘要： A pole-number-changing rotary electric machine includes: a rotary electric machine; an n-group inverter; and a control unit for controlling the n-group inverter, wherein the control unit controls current phases of a current flowing through stator coils such that a current phase degree of freedom, which is a number of current phases per pole pair controllable by the n-group inverter, is equal to a number of groups n×a number of phases m/2 at a time of high polarity driving and the number of groups n×the number of phases m at a time of low polarity driving, where the number of groups n is a multiple of 4 and the number of phases m is a natural number of 3 or more and relatively prime to the number of groups n.

摘要： A rotating electric machine including a rotator including a small-angle rotator portion and a large-angle rotator portion respectively having different inter-magnet end angles, each being a plane angle formed between a line connecting one outermost peripheral-side end of a permanent magnet and an axial center of the rotator and a line connecting an outermost peripheral-side end of another permanent magnet and the axial center of the rotator. The rotator includes three layers of the small-angle rotator portion, the large-angle rotator portion, and the small-angle rotator portion, which are laminated in the stated order along an axial line of the rotator. Therefore, demagnetization due to a temperature rise of the permanent magnets is suppressed. In addition, a temperature distribution in the permanent magnets in the axial direction of the rotator is reduced.

摘要： Permanent magnets that form individual magnetic poles are configured by arranging three magnet blocks to be spaced apart from each other circumferentially, the three magnet blocks are each formed such that cross-sectional shapes that are perpendicular to a central axis of a rotor core are radially outwardly convex, and circumferential widths are narrower in magnet blocks that are further away from a magnetic pole center, and the three magnet blocks that are arranged circumferentially are formed to have mirror symmetry relative to a plane that passes through the magnetic pole center and the central axis of the rotor core.
