GOOD VIBRATION
Supplied by Audimat, official Italvibras distributor : mechanical exciter with rotational motion for medium and large vibrating machines. No built-in motor — it is driven by an external motor.

The VR 17500/6-S08 is a mechanical exciter, size 310, with rotational motion. Depending on the weights fitted, it delivers 348 to 386 kN. It is driven by a motor rated at 18,5 kW.
The force is set simply by choosing the additional weights. Audimat is an official Italvibras distributor.

| Configuration | Part no. | Static moment | Max. speed | Force | Weight of pair |
|---|---|---|---|---|---|
| 1U — minimum weights | 0605054 | 18685 kgmm | 1303 rpm | 348 kN | 382+382 kg |
| 2U — maximum weights | 0605055 | 35175 kgmm | 1000 rpm | 386 kN | 450+450 kg |
The working moment is twice the static moment. Fitting more weights increases the moment but lowers the maximum permissible speed.
The difference is fundamental. A conventional vibrator motor contains its own electric motor and is wired directly. A mechanical exciter does not : it is a set of eccentric weights mounted on bearings, driven by an external motor that you select and size yourself. That is why the catalogue quotes a rating in kW rather than a voltage or a current.
This approach makes sense on medium and large machines : separating the vibrating part from the driving part reduces the loads on the motor and extends the service life of the whole assembly. The catalogue also stresses the care taken over noise reduction and over the durability of bearings and gears. The exciter is built around an induction motor driven from outside.
The force is not adjusted by phasing weights as on a vibrator motor, but by choosing the additional weights. The table above gives the two extreme configurations ; several intermediate values are available between them.
