Abstract:
A stator (12) of a rotary electric machine includes a stator core (21), coils (22) and magnetic bodies (44). The stator core (21) comprises a plurality of teeth (23) protruding towards the rotor and being spaced apart from each other and a plurality of slots (24) arranged between two adjacent teeth (23). The coils (22) are formed out of coil bodies (42) being stacked in radial direction, thus the direction into which the teeth are extending, and are wound inside of slots (24) around the teeth (23). The magnetic bodies (44) are arranged between adjacent coil bodies (42). The thickness of the magnetic bodies (44) in radial direction increases with increasing length of the tooth (23) or with decreasing distance towards the air gap between rotor (14) and stator (12).
