METHOD FOR MANUGACTURING A PERMANENT-MAGNET EXCITED ROTOR FOR A HIGH SPEED ELECTRIC MOTOR
摘要
The invention relates to a method for manufacturing a permanent-magnet excited rotor for a high speed electric motor, according to which method a support sleeve (1) is mounted with a pre-tension around the rotor body (2), characterised in that the sleeve is expanded by a liquid that solidifies and is solid at the working temperatures of the rotor, said liquid is injected under pressure between the sleeve and the rotor body and held under pressure during solidification.
