Re: Brushless motor Wiring

Make sure you know what direction you want the motor to be spinning then connect the motor to the esc, doesn't matter which way. IF the motor is turning the wrong way then switch ANY two plugs, does not matter which two.

You basically have a 50/50 chance of getting it right the first time.

Re: Brushless motor Wiring

Re: Brushless motor Wiring

I guess they don't bother with the colour coding on some as they run just as efficiently either way.

Depending on the application, you may have to alter are some or the ESC programming options. For example, with a heli you do not want BRAKE active which is the default setting on quite a few. On many you can also select which shutdown mode will take effect when it reaches the cutoff voltage point. Normal is SOFT which slowly drops power to the motor as it gets close. Personally I never liked this as it too often simulates what can happen if the battery actually runs out of juice. With LiPos that point is down into the damage range where you can kill the pack. The HARD cutoff does just as it sounds and immediately cuts motor output at that point.

There should be other options, such as motor timing, etc. If you are unsure, give us the make and model of both ESC and motor and perhaps someone will already have figured out the best combi.
I know there's money in aviation........I put it there!

Re: Brushless motor Wiring

I think I'm in good shape now

the documentation witht he speed control shows the 3 wires and says "To motor" If it does not matter what wire goes where then i should take all those curse words i said about the esc maker.

Its going in an indoor foam flyer plane.

years and years of wires having to go to certian wires had me a bit ocncerned i would let more majic smoke out
