Abstract (en)

[origin: WO9745937A1] In a device for increasing the mechanical rigidity and natural frequency of the stator in a rotating electric machine, which stator is provided with teeth (10) between the slots (8) receiving the winding, the free ends of said teeth being located in the air gap (7) between stator and rotor, a spacer (11) increasing rigidity is arranged in each space between the free ends of adjacent stator teeth (10). These ends are thus fixed tangentially.
