Abstract
A rotor (10) comprising a cylindrical structure (30, 31) including a portion made from a fibre reinforced composite (38, 39) wherein magnetic filler within the matrix (44) of the composite and wherein the loading of the magnetic filler material varies through the matrix whereby the average mass per unit volume of the structure (10) decreases with distance radially from the axis of the structure (10). As a result, strain matching across the rotor can be achieved even when the rotor is spinning at high speed, such as when used in a flywheel energy storage and conversion apparatus.
Claims16
A rotor comprising a cylindrical structure including a portion made from a fiber reinforced composite wherein magnetic filler material is incorporated within the matrix of the composite and wherein the loading of the filler material varies smoothly and continuously through the matrix whereby the average mass per unit volume of the structure decreases with distance radially from the axis of the structure.
