Title: (EN) Pole retention configuration for electric machine rotors
Abstract: front page image
(EN)

A retention system in which rotor pole pieces are retained within complementarily shaped channels in a rotor hub, permanent magnets are secured between the pole pieces and within clamp members, and wedge-shaped pieces are used to apply positive locking forces along the axial length of each clamp member and of adjacent pole pieces. A curable resin preferably in disposed within gaps between the permanent magnets and the clamp members.
