ABSTRACT:
An electrical machine, such as a transverse flux motor, incorporates a stator core assembly1. The stator core assembly1comprises a stator frame4upon which stator cores2,3are located with spacer elements7therebetween. A number of stator pole members10,11are located such that channels13in these members10,11accommodate limbs5,6of the cores2,3. The stator pole members10,11straddle more than two limbs5,6in order to provide greater structural stability for the assembly1despite magnetic flux cycling and other distortion effects. By such greater structural stability more accurate control of a gap between the stator core assembly1and a rotor in the machine can be maintained.
