Abstract:
A rotor of a reluctance motor, the rotor having an axis of rotation and comprising:a cradle having recesses and an axis corresponding to the axis of rotation of the rotor, wedge-shaped members received in the recesses of the cradle so as to be arranged about the axis of rotation of the rotor, each of the wedge-shaped members being a section of a solid composite body and comprising an arcuate surface defined by coaxial arcuate regions of at least one of a soft magnetic region and at least one of a second region of a material with dissimilar magnetic properties to the soft magnetic region so that the second region serves as a flux barrier to the soft magnetic region, the soft magnetic region of each of the wedge-shaped members being formed of a compacted soft magnetic powder material, the wedge-shaped members being arranged in their respective recesses so that their arcuate surfaces are adjacent the axis of the cradle and face each other; and a binder bonding the arcuate surfaces of the wedge-shaped members to the cradle to form the rotor of the reluctance motor.
