ZIEHL ABEGG EC BLUE FAN MOTOR | TROUBLESHOOT AND TEST 

Awesome vid. recently ran in to these motors and didnt jump the dc output to the ai which i could of now seeing the video but instead used a 9 volt battery lol

We used these in our chillers and so far they are ok . We use 24 volt start signal from a control board then analog the 0-10 vdc

Great video. Thank you for sharing. Have a nice weekend. First time, I see this type of this motor. You opened my eyes ^_^

I want to learn HVAC, but there are those who say the learning period is 6 months, and there are those who say 2 years, and there are those who say 4 years, which is true?

Those are heavy suckers too. Thx!!

Saludos...como programo el ventilador para que trabaje con voltaje de 10vcd?

Esta conectado original al am-modus y no trabaja...me gustsria tratar de hacerlo trabajar por 0-10vcd

Those ECM condenser fan motors are junk. So many of them fail, and its not just one brand....its all of them. We service a site that has 2 RTAF'S. Each chiller has 14 fans and between the 2 chillers we have replaced 12 motors already, same with RTAC's. Had it happen with dry coolers, chillers, fan walls etc etc. Give me a conventional synchronous motor and a VFD

Hai bro,how to check the winding in this EC fan motor? Please make video

Ya realice el puente y no trabaja

Ive only had to replace one of these motors, it was already diagnosed

You wasted time with those screws. You could have fast forwarded that to get to the real content of the video
