| 简介 |
A rotor (10) particularly for a high speed electric motor has a rare earth magnet core (12) within a sleeve (14) forming the rotor shaft. The core (12) is axially compressed between opposed end pieces (16, 18) secured to the sleeve by welding, adhesive or heat-shrinking. Radial compression may also be applied to the core (12). A method of assembly of the rotor (10) has the steps of axially compressing the core (12) between the end pieces (16, 18) and securing the sleeve (14) to the end pieces (16, 18) while the core (12) is pre-stressed. |
