Abstract: A brushless motor comprising a frame; a rotor assembly comprising a shaft, a rotor core and a bearing assembly, the bearing assembly being mounted to the frame; and at least one stator comprising a C-shaped stator core, the stator core comprising a back and first and second arms, wherein at least one of the first and second arms includes a protrusion that contacts the frame so as to inhibit radial movement of the stator core towards the rotor assembly.

Abstract: A method of manufacturing a rotor assembly, the method comprising: providing a magnet in an uncured state comprising a magnetic powder and a binder; providing a shaft onto which the magnet is to be fixed; and assembling an intermediate rotor assembly in which the uncured magnet is positioned on the shaft. The method then comprises heating the intermediate rotor assembly to cure the magnet and to allow a quantity of the binder to leach from the magnet, creating an adhesive bond between the magnet and the shaft.

Abstract: A hair care appliance including a motor for generating an airflow through the appliance, the motor comprising: a frame for supporting a rotor assembly, the frame including an outer wall; and a rotor assembly including a shaft and an impeller, the impeller including a plurality of blades. An impeller housing portion of the outer wall surrounds the impeller. An inner surface of the impeller housing portion includes at least one groove extending in an axial direction and positioned such that the at least one groove extends along at least the axial extent of the blades of the impeller.
