Abstract: A brushless motor has a stator assembly, a rotor assembly, and a frame within which the stator assembly is housed. The stator assembly has a plurality of stator core sub¬ assemblies each comprising a stator core, a bobbin attached to the stator core, and a winding wound about the bobbin. The frame is overmoulded to the stator assembly. The frame comprises a plurality of apertures for introducing airflow to the rotor assembly in use.

Abstract: A brushless motor having a stator assembly, a rotor assembly rotatable relative to the stator assembly, and a frame within which the stator assembly and the rotor assembly are housed. The rotor assembly includes a shaft, first and second bearings attached to the shaft, and a permanent magnet attached to the shaft between the first and second bearings. The rotor assembly includes an impeller attached to the shaft, with the first bearing located further away from the impeller than the second bearing. The rotor assembly includes an o-ring mounted between the first bearing and the frame.

Abstract: A brushless motor has a stator assembly, and a frame within which the stator assembly is housed. The stator assembly has a plurality of stator core sub-assemblies each comprising a stator core, a bobbin attached to the stator core, and a winding wound about the bobbin. Each stator core has a back and first and second arms extending from the back. The frame is overmoulded to the stator assembly such that at least a portion of the back and the first and second arms of each stator core is exposed through the frame.
