•External vibrator (General-purpose vibrator) includes asynchronous electric motor with a shaft-circited rotor and unbalances mouted on the both ends of the shaft.
•Vibrator design provides for chatter stability of stator winding and mechanical strength of rotor shaft, bearing unit and unit parts.Electric motor stator is embedded into aluminum or cast-iron body that features terminal box and reinforced fastening elements to vibrator gear.
•Rotor shaft rests upon bearings.Unbalance adjustable units are protected with shrouds.
•Terminal box features a terminal bolck to connest stator terminals to.
•Current-carrying cable.Centrifugal force and vibration range may be adjustd by means of changing unbalances positions.
•When electric motor rotor starts to rotate,circular vibrations of vibrator and the gear attached hereto arise.
