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 having a stator core, a bobbin attached to the stator core, and a winding wound about the bobbin. Each bobbin has a connection portion for connecting to an adjacent bobbin in the stator assembly, and the frame is overmoulded to the stator assembly.
