<p>An electrical machine such as a brushless permanent magnet motor comprises a housing (6), a stator and a rotor defining an axis of rotation (A). The housing includes a main body and heat dissipating fins (10) extending from the main body; the heat dissipating fins extend at an angle intermediate a plane normal to the axis of rotation and a plane parallel to the axis of rotation (A).</p> |
