A motor stator (12) having increased flux-carrying capacity and a method of increasing the flux-carrying capacity is described; a sleeve (14) of ferro-magnetic material is first inserted into housing (12) of ferro-magnetic material, thereby increasing the thickness, and consequently the flux-carrying capacity, of the housing, a mixture of plastic and magnet powder is then injection moulded into the housing/sleeve and passes through perforations (30) located in the sleeve to adhere to both the sleeve and the housing and form arcuate magnet segments (16, 18); resulting in stronger adhesion between the magnets and the housing/sleeve and increased flux-carrying capacity of the steel behind the magnets. |
