3. Safety
3.1. Intended Use
Vibrator motors are not independently functioning machines.
They are used to drive vibrating machines, such as vibratory feeders,
conveyor pipes, sieving machines, sorting machines and as flow aids in silos and
bunkers.
These machines use vibrations for sieving, conveying, loosening, compacting and
sorting.
Any other use is considered improper.
Vibrator motors generate destructive forces due to their design.
The vibrating machine must be designed for the forces generated by the vibrator
motors.
The operator is responsible for the operation of vibrator motors.
3.2. Qualification of staff
Installation, commissioning and maintenance may only be carried out by
authorized and qualified specialist personnel.
The electrical connection may only be carried out by a qualified electrician or
electrical trained person according to EN-60204-1.
3.3. Personal protective equipment
When working on vibrating motors, the following must always be worn:
- Protectice work wear
- Safety gloves
- Safety shoes
- Safety goggles

6
3.4. General safety information
Vibrator motors generate vibrations. The operator of vibration systems
must protect employees against actual or possible risks to their health
and safety from the effects of vibrations.
Würges Vibrationsmotoren GmbH accepts no responsibility for damage to
property or personal injury if technical changes are made to the product or
the information and regulations in these operating instructions are not
observed.
Live parts can cause serious or fatal injuries.
When working on the motors, they must be disconnected from the
electrical network. Proceed as follows:
1. Turn power off
2. Secure against being switched on again
3. Check that there is no voltage
4. Let the motor cool off
5. Ground the motor
The vibrator motors must not be touched during operation or shortly after
switching off. The surface temperature of themotor can reach such high
values during operation that there is a risk of burns.
Always tighten screws / nuts with a torque wrench! For the required
tightening torques for fastening, see page 12, the maximum tightening
torques for the unbalance fixing (pages 18 & 20) and the terminal board
nuts (page 15) must be observed.
Vibrating motors of the HV / FV / IV / INV / VFL / HF series must not be
used in potentially explosive areas.

4.3. Design and Function
The electric drive of the series is an asynchronous motor.
The exception is the type HV 2 GL, where it is driven by a permanent magnet-
excited direct current motor with carbon brushes.
There are eccentric unbalance discs on the two shaft ends of the motor.
This is understood to mean a rotating body, the mass of which is not distributed
rotationally symmetrically, and which thus generates vibration.
This vibration can be dosed by adjusting the weights.
You can find construction details from p. 25.

To prevent possible overloading, each vibrator must have its own motor
protection switch, the tripping current of which must be set in accordance with the
data on the nameplate.
If there are two, counter rotating motors running, it must be ensured that if one
motor fails, both motors switch off at the same time
(see circuit diagram on page 24).
Only flexible cables may be used for connection. We recommend the following
cable types:
HV 0,4 - HV 1: H 05 RN-F 4G0,75²
HV 2 - HV 85: H 07 RN-F 4G1,5²
from HV 75: NSHTÖU-J 4G1,5² (or H 07 RN-F 4G1,5²)
HV 2 GL: H 07 BQ-F 2x2,5²
HF: H 07 RN-F 4G1,5²
Plastic cables are unsuitable. Attach isolated cable lugs to the wire ends. Under
no circumstances solder cable lugs, as vibrations can cause the stranded wire to
break near the soldering point.

15
Insert the cable into the terminal box and connect according to the previous
diagram (see page 14).
Except for HV 0.4/2, HV 0.4/2-1 and HV 0.1, these have the appropriate cables ex
works.
When tightening the cable gland nut, make sure that the cable sheath is fully
covered by the seal. If this is not followed, the cable is not firmly clamped, not
strain-relieved and not watertight.
Carefully close the terminal box with the seal again.
The motor connection cable must be laid firmly approx. 0.5 m after exiting the
motor. The first fastening point of the cable and the motor must not be able to
move against each other during operation. The connection cable must be laid in
such a way that natural vibrations are avoided and no tensile stress
he follows.
During the initial start-up, the current consumption must be checked in all three
phases. Should this be larger than the one on the nameplate
specified value can be remedied by reducing the centrifugal force (see chapter 7).
The cable must be checked from time to time for chafe marks and, if necessary,
the cause must be eliminated.

6.3. Speed Control
With our three-phase vibrating motors, the speed can be regulated with frequency
converters.
The output power of the frequency converter should be approx. 1.5 times the
rated motor power (P1 / Pin).
Please inquire about the maximum permissible final speed for each motor type.
The speed reduction, up to approx. 20 Hz, is problem-free in any case
possible.
If the speed is increased above the value specified on the
nameplate, there is a risk of accident due to impermissibly
high centrifugal force.
The centrifugal force must be reduced!
The motors of the HF series require a frequency converter for power supply.
They can be operated with both a variable frequency and a fixed frequency.
When using a frequency converter, compliance with the EMC directive must be
observed.
In this case, we recommend using a shielded connection cable.
6.4. Permissible operating temperature
The temperature on the stator frame should not be higher than 80 ° C.
This limit can be exceeded if the current consumption is too high if the speed
specified on the nameplate is not reached. This can cause the winding to burn
out.
Possible cause is a centrifugal force that is too high for the application or an
insufficiently rigid construction.
By resetting the centrifugal force or using a device with more powerful
electric drive can help.
Ambient temperature must to be between -20 ° C and up to + 40 ° C
(for some types up to + 55°C)

17
7. Force Adjustment
Danger of crushing when setting the centrifugal force.
Make sure that the rotor shaft is fixed. The safety instructions
on page 6 must be observed!
If no special centrifugal force setting has been ordered, the motor is set to maximum
centrifugal force ex works.
The centrifugal force has a direct influence on the amplitude of the machine and
the current consumption of the motor.
To adjust the centrifugal force, dismantle both protective hoods (item 3, see p. 26
and following.) And loosen the unbalance fixation (item 30, p. 26 and following.).
7.1. Centrifugal force adjustment with plug-in
unbalance discs
For motors of size HV 0.4 to HV 15, HV 30/2, HV 55/2 and HF, the centrifugal
force is set in steps by means of plug-in unbalance disks.
The number of disks turned over must be symmetrical on both shaft ends (see
Fig. On page 18). Unbalance disks can also be removed for fine adjustment;
these must be replaced by spacers of the same thickness.
The centrifugal force is reduced by 180 ° by repositioning the unbalance disks on
both sides.
The centrifugal force of the motor is reduced in the case of a 180 ° rotated or
removed plug unbalance as follows:

7.2. Centrifugal force adjustment with swivel
unbalance discs
From size HV 12/4-60 (exception HV 30/2 and HV 55) the centrifugal force is
adjusted by turning the two outer unbalance disks.
The percentage centrifugal force can be either:
a) read off the scale on the shaft. One division corresponds to 10%.
or
b) read off the back (fixed) unbalance on the etched scale. One division
corresponds to 5%
The setting must be symmetrical (see illustration on page 20).

20
After the centrifugal force has been set, loosened screws
must be fastened again and the protective covers
reassembled (for tightening torques see below). Otherwise
there is a risk of accident! In order to guarantee the tightness
of the motor, it is important to ensure that the seals are intact
when dismantling and assembling the protective covers.
Damaged seals must be replaced.
Operating the vibrator motors without unbalance discs
is not permitted.
