Abstract: A method of manufacturing a rotor (4) for an electric motor is described, said method comprising the steps of: a) providing a magnet made of a sintered magnetic material, said magnet having a first diameter; b) providing a radial holding sheath made of a composite material, said sheath having an inner diameter which is smaller than the said first diameter; c) reducing said first diameter of said magnet to a second diameter; d) fitting said radial holding sheath onto said magnet when said magnet has the diameter; and e) letting the cylindrical magnet with the sheath fitted thereon interfere, thus allowing the sheath to exert inward pressures on the cylindrical magnet. The invention also describes a rotor which can be obtained with the method described above.
