Abstract

A rotor of a high-speed electric machine comprises a shaft (1), a magnetic circuit (2) embracing the shaft (1), a tread ring (3) and permanent magnets (6) mounted between the tread ring (3) and the magnetic circuit (2). The tread ring (3) is fixed to the shaft (1) by means of coupling elements, whereas the permanent magnets (6) are mounted on the internal surface (5) of the tread ring (3) with a gap (7) in relation to the magnetic circuit (2).
