摘要： The oscillating mechanical device comprises a shaft on which an oscillating member is mounted, and which is resiliently urged towards a middle angular equilibrium position, together with a single-phase induction motor whose rotor is coupled to the shaft so as to enable oscillations of the shaft to be sustained. According to the invention, the stator of the single-phase induction motor is fed with an alternating drive signal whose frequency is adjusted to the vicinity of the natural frequency of oscillation of the mechanical device. More particularly, the frequency of the drive signal of the stator is set to lie in the frequency range �f-0.8 Hz; f+0.1 Hz!, where f represents the natural frequency of oscillation of the mechanical device, and is preferably set to the natural frequency of oscillation of the mechanical device with a tolerance of plus or minus one-tenth of one hertz. The device is applicable to card web combs used in the textile industry.
