Abstract
A hub for a rotor of a permanent magnet motor comprises fluid conduits which extend radially outwardly to a region radially beneath each magnet of the motor and then radially inwardly. A rotor of a permanent magnet motor is also provided which includes a hub body having a plurality of lugs on an outer circumferential surface of the hub body, each lug substantially consisting of a tapered base portion and a head portion. The maximum width of the base portion of each lug in the circumferential direction substantially corresponds to the circumferential distance between the adjacent permanent magnets. Furthermore, a rotor of a permanent magnet motor comprises rotor segments having axially extending grooves defined in a radially extending sidewall of each rotor segment.
