Abstract

An electric machine () comprises a turbomachine rotor () having a hub () and an axis of rotation (A-A) about which the turbomachine rotor is arranged to rotate. The turbomachine rotor includes a plurality of blades (). Each blade has a root () attached to the hub, a tip () remote from the hub, a leading edge () and a trailing edge (), a pressure side and a suction side (). A stator () is located circumferentially around the turbomachine rotor. Each blade further comprises a rotor element at the tip comprising a permanent magnet having a first pole () and a second pole (), the first pole being located adjacent the suction side of the blade and the second pole being located adjacent the pressure side such that a magnetic flux path extends perpendicularly through the blade tip.
