Electric machines with stator or rotor sleeves have a wide range of application. Rotating sleeves for example are used for high speed rotors to protect magnets against centrifugal forces. Stator sleeves can be used to shield machine components from the process fluid, also called canned motor pumps. Composites are the first  choice for such applications as they are almost transparent for magnetic field, have an excellent stiffness,  strength and are easy to machine. AEC Kaiserslautern developed enhanced filament winding process has  considerable advantages over conventional techniques leading to superior outcomes in strength and  consistency. Filament winding technology provides an extreme pre-tensioning of the rotor magnets in radial direction which leads to extraordinary thin sleeve material. Low clearance between rotor and stator combined  with the transparency of composite materials for the magnetic field in combination with the high mechanical properties and noncorrosive properties leads to high efficient electric machines using filament winding technology.
