	The paper presents an analysis of vibrations in the electric propulsion system for a test stand for a prototype helicopter main rotor. The propulsion system includes an induction electric motor to provide power to propel a main rotor equipped with prototype blades of variable geometries. Mounted in the blades, the actuators made of shape memory material are capable of changing the geometric twist angle of the blades during the main rotor operation. Such an element can additionally affect the vibration of the entire propulsion system. The resonance phenomenon can lead to the disintegration of the entire structure of the test stand or the rotorcraft. The dynamic instability phenomenon results in machinery, vehicle or aircraft malfunctions. In the investigated high-speed system, vibrations have a key diagnostic role, which explains the need for their detailed analysis
