Abstract
The motor () has a rotor () which can rotate around a rotation axis (A), and a specific number (N) of magnetic poles (). Furthermore, the motor () has a stator () which is arranged coaxially with respect to the rotor () and has three stator teeth () for each two magnetic poles (), which stator teeth () are distributed uniformly around the rotation axis, with center points of mutually adjacent stator teeth () being separated from one another by one slot pitch (Pc). The stator teeth () have free surfaces (Ss') which are opposite the magnetic poles (). Each stator tooth () is provided with one, and only one, projecting element (), which extends radially from the respective free surface (Ss′) in the direction of the rotor ().
