Abstract

A stator arrangement for a small motor, particularly of the claw-pole type. The stator arrangement is provided with first and second stator subassemblies which are formed from respective pairs of pole laminations which are contained within a common housing. The common housing is provided with axial slots having predetermined circumferential width and axial depth for engaging radial protrusions of the pole laminations. In this manner, the axial and rotative orientation of the pole laminations, and the stator subassemblies, are advantageously predetermined within the cylindrical housing.
