A push-pull electromagnetic AC vibrator comprises two electromagnets having two windings located from opposite sides of an electromagnetic armature fixed to a movable system, and two identical resonance circuits formed by a second winding of each electromagnet and a capacitor attached to it. A first winding of each electromagnet is connected to an AC source via a capacitor of the resonance circuit connected in series to it. On each electromagnet, a third winding connected in series with the second capacitor is located, each connection is connected in parallel to the first winding of the opposite electromagnet. On each electromagnet, a fourth winding connected in parallel to the second capacitor the opposite electromagnet is located. |
