Low-inertia permanent-magnet electrical machine rotor |
摘要 |
A rotor (11) for an electric machine with low-inertia permanent magnets (13) located between the poles (15) of the electric machine and a rotor hub, where the rotor hub is comprised of an internal ferrule (21) and an intermediate ring (23) between it and said magnets (13), with said intermediate ring (23) being made of an amagnetic material (such as aluminum, a composite material or a plastic material) of minimum thickness which prevents flux losses, and with the internal ferrule (21) being made of a metal material (such as cast iron or steel) with sufficient thickness to resist, together with the intermediate ring (23), the mechanical stresses caused by rotor (11) operation. |
