applications and areas. In this case, the user must make appropriate protection arrangements during the

installation.

The following points should be considered for the matters not mentioned in this instruction,

1. Technical data given in the catalog and on the name plate

2. Information about the facility to use the vibration motor

3. Protective measures according to where the vibration motor will be used

Our vibration motors are 2 (TWO) YEAR WARRANTY. But; vibration motors not operated under

the conditions specified in this instruction, catalog, and name plate or not having the necessary

protection schemes in accordance with TS 10316 - EN 60204-1 are excluded from the warranty.

The structural changes to be made on the parts and repair and maintenance operations by

unauthorized personnel shall cause the vibration motor to be excluded from the warranty.

Bearings used in vibration motors are not guaranteed by the bearing manufacturer.

1.1. OPERATING CONDITIONS

Standard vibration motors, designed to operate at rated voltage and frequency (380 V, 50 Hz), -15 ÷

+40 °C ambient temperature and at sea level up to 1000 m.

Standard vibration motors within the scope of this operation and maintenance instruction are totally

enclosed, non-ventilated, and IP55 protection class. Measures should be taken for the vibration motors which

operating outdoors to protect against rain, snow, dust etc.

1.2. TRANSPORTING

80 and 90 frame motors have a lifting eye and bigger frames have lifting holes.

If the vibration motor has to be lifted together with additional loads, such as the chassis or the

driven machine; the additional loads must be lifted by their own system.

Vibration motors should never be placed on the fan covers and they should not be transported

and stored in this way.

1.3. STORAGE

The vibration motor must be checked visually if it is damaged or not during transportation. If the vibration

motor is to be stored for a long time, it must be kept a place which is clean, free of moisture and vibration.

1.4. SAFETY

Vibrating motors are connected to the power supply network and are rotated by magnetic induction. When

they transported, installed, used and maintained according to this operation and maintenance instruction, it

does not endanger any life

Vibration motors are industrial products. In this regard, the installation process must be carried

out by experienced and qualified personnel. Vibration motors are manufactured by taking

precautions against earth leakage and / or static electricity.

1. GENERAL INFORMATION

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.

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.).
