Electrical machine with hybrid tooth design

Provided is a stator segment for the stator or the rotor of an electrical machine including a segment body circumferentially extending about a longitudinal axis of the stator segment between two circumferential ends. The segment body includes: a plurality of teeth protruding according to a radial direction orthogonal to the longitudinal axis, each tooth circumferentially extending between two respective side faces, the teeth being circumferentially distributed between two end teeth of the teeth, the teeth including at least one intermediate tooth circumferentially included between the end teeth, a plurality of slots, the plurality of slots including a plurality of intermediate slots circumferentially included between the two end slots, wherein side faces of the two end teeth are inclined with or parallel to each other and the side faces of the at least one intermediate tooth are respectively parallel to each other or inclined with respect to each other.
