Abstract
A motor having flux-concentrating permanent magnets, the motor including a stator with windings and a rotor including a shaft, a sleeve surrounding the shaft for holding rotor laminations, and permanent magnets. The motor being characterized in that said sleeve is constituted by unitary sleeves (2) separated by disks (5), the sleeves and the disks being clamped together by tie bars (6) connected to at least one end cheek plate (7) which is fixed to the shaft (1).
