75m cable length possible thanks to our sine filter

Not all the applications allow the control panel to be placed near the motors. In this case, we wanted to verify if the use 75 m cables between the control panel and the motor is possible. Why do we do it? I'll tell you in my next post.

In order to minimize losses of power and control quality, we inserted a KEB sine wave filter right after the drive output.

Additionally, we controlled two 2,2 KW asynchronous motors with a single 5,5KW drive. Only one of the two motors has an encoder and this is connected to the single drive.

The three motors are mechanically connected. The two shafts motor in the middle gives us the possibility to test different loads for the other two motors.

This kind of setup can be use in different applications allowing a clear cost reduction. 

Karel Sehnal from KEB Czech Republic and Mario Zellhofer from KEB Austria worked together to build up the test bench and start-up the system. Well, it works quite fine – well done guys!
