Abstract
A magneto rotor assembly is disclosed in which a magnet is clamped in position between a pair of pole pieces within a cavity in a rotor. The pole pieces are provided with at least one tapered surface which engages a or the corresponding tapered surface(s) of the rotor cavity to prevent movement of the pole pieces and magnet. A fastener is also provided to hold each pole piece in engagement with the rotor cavity.
Claims7
A magneto rotor assembly in which a magnet is maintained in position between a pair of pole pieces within a cavity in said rotor, said pole pieces are provided with two tapered surfaces and said cavity is provided with two corresponding tapered surfaces, one of said tapered surfaces extending in a radial direction to hold said pole pieces against outward movement away from said magnet and the other of said tapered surfaces holding said pole pieces against radial movement each said pole piece and said rotor cavity tapered surfaces being mutually engagable to clamp said pole pieces against said magnet within said rotor wherein a fastener holds each pole piece in engagement with said rotor said two tapered surfaces having normals which are substantially mutually perpendicular and lie approximately in a plane and which is substantially perpendicular to the longitudinal axis of said fastener.
