Description

For the investigation of free rotary oscillations at different dampings (aperiodic, creeping and limit adjustment) and of forced oscillations (resonance curves, phase changes between exciter and resonator). Oscillation system consisting of ball-bearing wheel, which is connected to the driving rod via a spiral spring. Driven via eccentric by an electromotor with fine and coarse speed adjustment. Damping by electromagnetic eddy-current brake. With scale ring and pointers at exciter and resonator; can also be used for shadow projection. Includes electric motor mounted on base plate.
