Very interesting link Les. Alot of good info. I'm sorry for distracting from the original thread topic, but I was wondering if BillA ever did the TIM test with the copper spacer in the middle?
Back on topic: Cathar, how did you arrive at the 50 to 60% figure for pump motors? I had read in another thread where myv65 said motor efficiency was around 75 to 85%. Is there something different with regards to pump motors that decreases it to your value, or was myv65 just wrong?
