Zusammenfassung:A rotor assembly for a permanent magnet electric motor defines an axis of rotation and includes a jacket member and a magnet member that is received within the jacket member. The magnet member defines a central aperture. The rotor assembly also includes a shaft structure with a base member and a biasing projection that projects from the base member. The biasing projection is received within the central aperture of the magnet member. The biasing projection biases the magnet member toward the jacket member in an outward radial direction away from the axis of rotation for retaining the magnet member and the jacket member together.
