RE: E-C/L ... 3 cell LiPo battery cut off

I know what 3-phase power is and how a 3-phase motor works - These are three phase motors. There are 3 distinct windings, connected internally in either delta or Y configuration. Either way, there...

The ESC -

The motors have three windings, connected to 3 leads and no commutator or brushes. All the commutation and "logic" of applying power to those windings takes place in the Electronic...

RE: E-C/L ... 3 cell LiPo battery cut off

These are brushless, 3 phase motors. You can't just connect power to the leads and have them run. They need an Electronic Speed Control (ESC) in order to turn at all - the ESC normally recognizes...

RE: E-C/L ... 3 cell LiPo battery cut off

Here is some info on Will Hubin's Flight Managers - there are other options, but you need more expensive esc's to take advantage of them, so I've only shown the two that are "plug and play" for the...

RE: E-C/L ... 3 cell LiPo battery cut off

Go to Lightflightrc.com - he has the "Suppo Cheap Combo" for about $18 - this is a motor and speed control. Get the motor with the highest Kv (a motor constant that kind of describes how it can run)...

I don't know if you guys are still interested in this thread or not, but I thought I'd show some pix of what it triggered - I decided that I'd just build something so anyone would be able to have a...

RE: E-C/L ... 3 cell LiPo battery cut off

Are you talking about brushed motors ? If so, then yes, you only need some kind

RE: E-C/L ... 3 cell LiPo battery cut off

Well, there are two issues - first, you must use an ESC, at least for a modern

RE: E-C/L ... 3 cell LiPo battery cut off
