Abstract

I en anordning for å øke den mekaniske stivhet og naturlige frekvens hos statoren i en roterende elektrisk maskin, hvilken stator er forsynt med statortenner mellom slissene (2) som holder viklingen (12), av statortennene (4,6), hvis frie ender er plassert ved luftgapet mellom statoren og rotoren, minst et åk (14) dannet i et stykke med hosliggende stator- tenner, anordnet over hver statorslisse for mekanisk å feste statortennene i den tangensielle retning.In a device for increasing the mechanical stiffness and natural frequency of the stator in a rotary electric machine, the stator is provided with stator teeth between the slots (2) holding the winding (12), of the stator teeth (4,6), the free ends of which are located at the air gap between the stator and the rotor, at least one yoke (14) formed in a piece with adjacent stator teeth, arranged over each stator slot to mechanically secure the stator teeth in the tangential direction.
