1. A rotor for an electrical machine having a plurality of poles, wherein each of the plurality of poles comprises a radial axis centrally through the pole, each of the plurality of poles further comprising:
a first slot configuration having a magnet, the magnet being substantially perpendicular to the radial axis; and
a second slot configuration having a pair of magnets located at spaced apart positions within the second slot configuration, the pair of magnets located each side of the radial axis and at an acute angle to the radial axis to form a generally V-shaped second slot configuration,
wherein the first slot configuration is located between the second slot configuration and an outer perimeter of the rotor,
wherein each of the plurality of poles further comprises two first slot configurations, an inner one of the two first slot configurations comprising a first slot portion which is perpendicular to the radial axis, with the magnet located within the first slot portion, a third slot portion and a fourth slot portion,
wherein the third slot portion and the fourth slot portion are at opposite ends of the first slot portion, and the third slot portion and the fourth slot portion are at an acute angle to the radial axis, and
wherein an outer one of the two first slot configurations comprises a first slot portion but not a third slot portion or a fourth slot portion.
