Marke,
I know that PSC motors Efficiency is best for the loading that they were wound for. The application is hermetic HVAC compressors that have a load for rating and a wide range of loadings depending on the system, weather conditions, controlled space set point etc. etc. The need is to...
Finally someone asked about the run and start capacitors. I don't think that a fault in this area would cause bearing failure though. At this point should opt for misalignment and check for it. Be agressive. Cut the motor open with a cutoff wheel or something. Especially if it occurs again...
What are the best techniques for improving PSC motor part load efficiency? The application load is frictional VS inertial.
Also 3-Phase motors, same type of load?
