Reading A Motor Name Plate

In a motor nameplate the main data are motor power in kw(HP), motor rpm(revolution per minute), volts, F.L.A.(full load ampere).


On the above name plate we can see the motor company - Motor & Co GmbH,

It is three phase motor, if it is connected delta then its phase to phase voltage will be 400V and if it is connected in star then its phase to phase voltage will be 690V.

Here we can notice another thing is when phase to phase voltage is 400V then full load current is 29A and when phase to phase voltage is 690V then its full load current is 17A.

Its maximum power is 15 kW and power factor is 0.85. Its rpm is 1430 rev/min and supply frequency is 50 Hz.










If you want to run a motor in delta connection then connect the six terminals above.









If you want to run a motor in star connection then connect the six terminals above.

Thanks a lot for this moment. Still many important topics are waiting for you.
