Würges electric vibrators HVE/VFLE are de-
signed and built to state-of-the-art standards
and operate safely if used as intended.
They conform to Category 2 for explosion
hazardous areas of Dust Zone 21/22 and Gas
Zone 1/2.
The provisions of EN 61241-1-2 have to be
heeded, e.g. pertaining to temperatures and
dust accumulations.
The Operating Instructions have to be read
and understood by every person at the user’s
company who is assigned with assembly,
setting up, start up, the maintenance and
repair of vibration motors. This also applies
for additional instructions in case of modified
devices.
The instruction manual must be
read carefully and in full before
using the vibrator motors.

The following information and hazard symbols are used in these installation and operating
instructions:
2. Symbols Used
ATTENTION Important information regarding operations or
procedures to which particular attention is to
be paid.
EXPLOSION HAZARD Refers to the possibility of fatal, severe or
irreversible injuries caused by use of the
product in an explosive atmosphere.
HAZARD Refers to the possibility of fatal, severe or
irreversible injuries caused by live parts.
WARNING Refers to the possibility of fatal, severe or
irreversible injuries caused by general hazards.
HOT SURFACE Refers to the possibility of severe or irrevers-
ible injuries caused by touching hot surfaces.
DISCONNECT Refers to the fact that the motor must be
MOTOR FROM MAINS disconnected from the electricity mains and
secured against being switched back on
again before any work is carried out on the
motor.
ENVIRONMENTALLY Refers to the obligation to ensure environ-
COMPATIBLE DISPOSAL mentally compatible disposal.

3.1. Intended use
Electric vibrators are not independently
functioning machines. They are used as the
drives of vibrating machines such as vibratory
conveyor troughs, conveyor pipes, screening
machines, grading/sorting machines and
knock-out grids.
These machines use vibrations to screen,
convey, remove, compact and sort or grade.
Any other use is deemed to be not as inten-
ded or misuse.
Electric vibrators are designed to generate
forces that can be destructive.
The vibrating machine must be designed for
the forces generated by the electric vibrators.
The operator shall bear responsibility for the
operation of vibration motors in explosion
hazardous areas.
3.2. Skilled personnel qualifications
The installation/assembly, startup and main-
tenance may only be carried out by authorised
and qualified skilled personnel.
3. Safety

3.3. General safety instructions
Electric vibrators generate vibrations. The owner of vibration machines must
protect their employees against actual or possible risks to their health and safety
caused by the effect of vibrations.
Würges Vibrationsmotoren GmbH refuses to accept the responsibility for any
damage to property or personal injuries if technical changes have been made to
the product or the instructions and regulations in this instruction manual have
not been noted and followed.
Live parts can cause severe or fatal injuries.
Electric vibrators must be safely disconnected from the electricity mains before
any work is carried out on them. The required procedure is as follows:
1. Switch off vibrator motor
2. Secure against being switched back on again
3. Test for safe disconnection from the power supply
4. Allow the vibrator motor to cool
Do not touch the vibrator motors while they are running or soon after switching
them off. The surface temperature of the vibrator motors can reach such high
values during operation that there is a risk of burns.
Always use a torque wrench when tightening screws or bolts! Tightening
torques see page 10. Attention to maximum tightening torques on page 14.
Vibrator motors of the HVE/VFLE series may be deployed in the explosion hazar-
dous areas 1/2 and 21/22.
The permissible ambient temperature must be between -20°C and +40 °C.

4.3 Design and function
The electric drive of the HVE model range is
an asynchronous motor.
The stator in the HVE 2 and VFLE 2 sizes
was cast under vacuum thus forming a fixed
assembly with the housing. There are unbal-
anced eccentric discs on the motor shaft
ends.
The unbalance is a rotating body whose mass
is unequally distributed in its rotational sym-
metry, and so causes a vibration as it turns.
This vibration can be dosed via weights and
counterweights.
Please see the data sheet of the motor for
additional technical specifications, or our
catalogue.
Possible voltage variants:
Motor type Hz V
HVE/VFLE 2/2 50 42 – 550
HVE/VFLE 2/2 60 42 – 550
HVE/VFLE 2/4 50 42 – 400
HVE/VFLE 2/4 60 42 – 440

When they are delivered the motors must be
checked for visible transport damage!
If the motor is visibly damaged
it must not be started up. The
vibratory motor must be examined
and if necessary returned to the
manufacturer for repair.
Until they are installed the electric vibrators
should be stored in enclosed, dry rooms at a
max. ambient temperature of 40°C.
Vibrator motors must always be stood on their
bases or footings!
Do not stack vibrator motors!
Do not lift up the motor by its
installed connection cable.
Note and follow the local accident prevention
regulations.

6.1. Assembly/Installation
Electric vibrators can be installed in any
installation position. Vibrator motors may only
be built on to machines with flat, oil, grease
and paint-free and flexurally rigid mounting
surfaces.
Surface quality
Only bolts in quality class 8.8 > EN ISO 4014
(DIN 931);
EN ISO 4017 (DIN 933) and nuts in quality
class 6 > 8.8 EN ISO 4032 (DIN 934) may be
used.
The bolts must be secured against mechani-
cal loosening by means of spring lock was-
hers DIN 127 Form A, DIN 7980 or Schnorr
washers.
The fixing bolts must be checked
for secure fit after approx. two
operating hours and if necessary
retightened. Other checks should
be carried out daily!
Improper fixing results in the
breakage of the feet of the
vibratory motor.
