Title: Axially-split stator construction for electric motors

Abstract: This invention relates to the construction of stators for use in electric motors. A stator for an electric motor comprises an elongate tubular body defining a central cavity in which a rotor can be located, the body defining a series of axial slots extending parallel to the body axis and a series of electrical conductors extending along the channels to form electrical windings, wherein the body is formed from at least two part-circular segments of substantially the same length, the segments together defining the central cavity.
