I'm new to this forum. I work in HVACR. I've been getting some great information from the HVACTalk forum for refrigeration side of things. I am here to get the same quality of information about the electrical side of HVACR. The electrical and motors topics typically have the lowest scores for NATE and other industry tests for HVACR people. So, I want to learn more in those areas.
My question concerns EMC motors and their control modules. Several HVAC people have been complaining about the control modules acting up in a variety of ways.
Could a failure to maintain a single point ground (isolated ground) cause control problems with these ECM motors, or are these control modules not electronic proportional controls and therefore aren't affected?
