Anyone check this and the Evergo? I remember some of you said you wanted a video of them. nope i didn't

i am guessing the fan being a little too fast at speed 1 may be due to the regulator, some regulators operate fans faster than they should be while some others operate much slower.. this kind of flaw usually occurs in transformer-type regulator i've seen several cases where the transformer-type regulator was the cause of speed difference MFD = UF. Two different abbreviations for the same thing. The value of the capacitor dictates the balance between the start winding and the run winding. The higher the number, the more current goes to the start winding, and the faster the motor will go. If the value is too high, the start winding will burn up. If the value is too low, the fan will go slower, and perhaps not start. 4uf is pretty low. I'd be surprised if it were lower than that. which winding is the start winding? the outer or the inner one? i remember we had a crompton parkinson that was operating on the replaced 2.25 uF capacitor for many years (originally it operates on 1.6 uF) the fan was operating much slower than it's maximum speed, when i obtained it and changed it's capacitor to 1.6, it works just fine, heats up almost as much as it used to with the 2.25 uF cap i also have an SMC (jul 1987) (HK-made SMC operates using 4 uF) that seems to have an originally installed 13 uF capacitor, it operates with very low acceleration as compared to other HK-made SMCs but faster, heats up a little more than other SMCs, should i go for changing it's capacitor?

Nah, like I said earlier in this thread AND in in the video, I've tried this fan with two different controls, a transformer type and a capacitive type that usually makes fans runs much slower and still it was the same speed as with the 5-speed control.

Happy ceiling fan day! Here's a revisit of this very powerful 1980 4 Saisons 90 cm with four metal curved blades originally acquired in December 2011.
