I'm back looking at controllers since the one I bought turned out to be defective. A few that I'm considering have a 3-way switch. I've always thought those switches simply limit power in some way (current, voltage, etc.) for the middle and lower settings, with full power on the high setting.
Looking more closely, I'm now wondering whether the switches are implemented differently depending on the controller and whether the middle setting is actually the full/normal power setting, based on reading the various product descriptions. One in particular states "Max speed up 20%. Sine wave controller's max effective flux weakening speed-up can be 20%...". I see other descriptions that don't mention flux weakening, but describe something that sounds like it.
So my question is, do most controllers with 3-way switches use some sort of flux weakening for the hi position?
