2. SETUP AND OPERATION_______________________
2.1. SETUP
During the stage of setting up the vibration motor, it should be taken into consideration that the
vibration motor can be easily reached during maintenance and repair times.
Vibration motors to work outside; The sun's rays should not come directly into the vibration
motor.
During normal operation, the vibration motor body may become too hot to touch. Therefore, the
vibration motor must not be touched.
2.2. INSULATION RESISTANCE
In case of vibration motors to be used after a long storage or waiting period, the insulation resistance
of the windings must be measured before commissioning. In the insulation resistance measurement process,
DC 500V is applied to the windings with insulation resistance measuring device (megaohmmeter) and the
resistance is read at the end of one minute.
Insulation resistance value measured at 25 ° C; 10 MΩ’ in a new vibration motor and 1 MΩ in a vibration
motor that has worked for a period of time.
If the measured insulation resistance value is below the limit values; winding must be cleaned and dried.
If the insulation resistance value is still low, the windings must be dried. Drying can be done in an oven or
with a heat gun. (heat gun temperature is 80 ° C)
Using DC voltage with the help of a transformer, drying can be achieved by applying a current not
exceeding 10% of the rated voltage and 20% of the rated current to the terminals U1 and V1 of the winding.
The insulation resistance must be checked again after the vibration motor has cooled down.
Do not touch the terminals during and after the measurement due to high voltage. After
measurement, the windings must be discharged immediately.

2. SETUP AND OPERATION
2.3. VIBRATION GENERATION METHOD
There are basically two vibration generation methods
2.3.1. Circular Method
In this method, vibration force is obtained in a circular direction in 360 ° clockwise and counterclockwise
using a vibration motor.
(Figure-1.a).
2.3.2. Single Direction Method
In this method, vibration forces are obtained in only one direction and sine curve by using two vibration
motors.(Figure-1.b).
a. Circular Method b. Single Direction Method
Figure-1. Vibration generation methods
2.4. SETTING THE CENTRIFUGAL FORCE
Vibration motors are vibrated with eccentric hammers on both sides of the motor. A total of four eccentric
hammers are available in a vibration motor with two fixed and two adjustable.
Our vibration motors are shipped with the eccentric hammers set to step 3 (85%).
The vibration force is increased or decreased by changing the positions of the tuned hammers. As the
angle between the fixed and tuned hammers increases, the vibration force decreases.
To adjust the vibration force:
 Remove the safety cover on both sides of the vibration motor.
 Loosen the bolts on the adjustable (outside) hammers.
 Rotate the adjustable hammers over the shaft to set them to the appropriate setting for your system.
 Tighten the bolts on the adjustable hammers.
 Install the safety cover on both sides of the vibration motor by checking that the sealing piece (oring)
between the vibration motor cover and the safety cover is properly installed.

6
2. SETUP AND OPERATION
The vibration motors must not be operated when the safety cover on both sides of the motor is
not installed.
The position of the hammers on both sides of the vibration motor, must be the same (parallel).
If the adjustment is made in a different direction, the position of the hammers on both sides is
not the same (parallel), the vibration motor shaft, the vibration motor mounting bolts and / or
the chassis to which the vibration motor is connected are damaged.

2. SETUP AND OPERATION
2.5. FIRST START AND RUNNING
Our vibration motors are manufactured as standard only for direct starting. For this reason, our
vibration motors have 3 pole outputs in the terminal boxes.
The suitability of the network that will feed the vibration motor to the vibration motor plate
information must be checked and the supply cables should be selected according to these values. If the voltage
difference is greater than ± 5%, the vibration motor windings may be damaged.
Check the tightness of the nuts at the terminals. Loosely nuts cause the vibration motor to
malfunction.
The user has the responsibility to protect the vibration motor against overload. The vibration
motor must be connected to the mains via a thermal-magnetic switch which is capable of
protection against overcurrents. The current setting of the switch must not be more than 1.05
times the rated current of the vibration motor. Otherwise, the vibration motor is not covered by
the warranty.
Overload protection will only be possible by sensing excessive heat caused by overload and other
reasons (two phases, excessive ambient temperature or altitude, excessive starting stop, etc.). Install a
thermistor in the winding and to connect the terminals coming from the thermistor to the thermistor relay is
necessary for overload protection.
PTC thermistors are mounted as standard on 132, 160, 180 and 200 types of vibration motors and
Phase Protection Relay is given as free of charge. On request, our smaller vibration motors are supplied with
a thermistor and are supplied with a relay.
Vibration motors of type 132, 160, 180 and 200 should be used with thermistors. Otherwise, the
warranty terms will be invalid.
2.6. ROTATION DIRECTION
Our vibration motors are designed to operate in both directions. The rotation direction of the vibration
motor can be changed by replacing any two of the mains phases in the connection diagram L1, L2 and L3.

2.7. FINAL CHECK
If the mechanical and electrical connections of the vibration motor are technically
appropriate, it shall be appropriate to start the operation after the following checks.
1. The operating conditions must be compatible with the vibration motor plate. (3~380V %5, 50Hz
%2)
2. If the vibration motors are not used for a long time, the insulation resistance values must be sufficient.
3. All mechanical and electrical connections must be tight.
4. The moving and energized parts must be fully protected against touching.
5. The position of the hammers on both sides of the vibration motor must be the same (parallel).
When the vibration motor is being serviced, the vibration motor must not be connected to the
mains power (no power) and must be de-energized in the auxiliary circuits (heater etc.).

3. MAINTENANCE
3.1. CLEANING
Before and after work, dust accumulated on the body should be cleaned.
3.2. BEARINGS
Vibration motors are equipped with long-life bearings that can carry axial, radial and combined loads without
problems.
3.2.1. Lubrication of bearings
Vibration motors are equipped with lubricating nipples and oil drain channels. The grease type and lubrication
range are indicated on the vibration motor plate.
In order not to deteriorate the chemical and physical properties of the greases, different types
of greases should never be mixed. When lubricating, be sure to use the type of grease indicated
on the vibration motor plate.
In the case of initial lubrication, no grease should be expected from the discharge duct. After
several lubrication, dirty grease will appear in the discharge duct.
 For re-lubricating bearings;
 Remove the grease drain plug
 Clean the dirty grease on the drain and make sure the drain is open.
 Clean the grease nipple and the tip of the grease gun.
 Pump up to half the grease of the quantity indicated in the table on page -11.
 Operate the vibration motor at full speed for several minutes.
 When the vibration motor stops, pump the remaining grease into the bearing.
 Install the grease drain plug.

3. MAINTENANCE
Refer to the vibration motor plate for current bearing and lubrication information.
3.2.2. Bearing Replacement
Dismantling of bearings:
 Roller bearings: The inner ring must be heated with flame and removed by means of a puller. If not,
the inner ring should be turned and refuted.
 Ball Bearings: After the inner ring has been heated slightly, it should be removed by using puller.
Never use hammer.
Mounting of bearings:
 The inner rings of the ball bearings and roller bearings must be heated to an average temperature of
80 ° C in the induction heater or in the oil bath (open bearings only). The heated bearing can be easily
installed on the shaft.
 When the bearings are mounted on the shaft, impacts from the outer ring must not be applied. Instead,
light impacts can be applied to the ring-type tools and the bearing inner ring made of the shaft diameter.
 When attaching the vibration motor bearing covers, suitable tools should be used with the cover
diameter.
To replace the bearings, the rotor and shaft assembly must be removed. During this time, the
stator windings must be observed and the windings must be protected.
A bearing must not be unpacked until it is installed. They must be protected from dirty and dusty
environments.
3.3. SEALING COMPONENTS
The sealing components (eg oring) between the vibration motor cover and the housing must be
correctly seated in the housing. Damage must be prevented when adjusting the vibration force.
Oil seals with 112 and 132 types and 160 types of vibration motors (excluding 7,5 kW - 1000 1 /
min) must be fitted with suitable tools.
The sealing components can be lubricated with machine oil before assembly. The sealing components
must be installed in the correct axis to the mounting locations. When they are not fitted on the right axis, they
cause excessive friction.
