Brushless Motor cw -ccw?
#1
hello, i was looking for motor pickup and i wanna pick one of the brotherhobby returner r2 or r4, and i noticed that all sellers of those motor have CW Screw Thread. After a search i confused with the cw and ccw direction. So if i pick these motors i choose direction from betaflight or i have to find ccw motor? The diference between brushed and brusless motors is that brushless motors spins both direction an brushed spin 1 direction?

You are correct that brushless can spin both directions. CCW and CW are just the screw thread shaft directions. Companies used to make most motors with CCW and CW threads. The purpose was when the motor is spinning, the nut self tighten. Currently, most companies only make CW thread, just because it is easier to find CW nut. You will not find a CCW thread for your motor because it does not exist. Just use a nut with nylon. You can set motor whatever direction you like in blheli suite (not betaflight).

For some motors and propellers, these might be too tall, but you can also get low profile ones:

If when you say threat (thread) you mean rotation, then yes, you are correct

I always order only CW motors if I can. Then you only need one kind of nylock nut.

Ordering motors with CW and CCW threads is only necessary if you are going to use standard nuts without the nylon locking ring. Standard nuts will unscrew themselves if you don't correctly match the motor rotation with the screw thread.

Edit: sorry RENOV8R, I meant the OP is a little confused not you.

I think you (OP) are a little confused. CCW and CW props will go onto either CCW or CW motors and vice-versa. There is no threads on the props. The nut is what holds down the prop.

Like unseen said, do yourself a favor, just get CW motors and CW nuts. That way you only have one kind of nuts to deal with. If your are desperate and run out of aluminum lock nut, you can always go to the hardware store and buy CW steel lock nut just to get you back flying.

You will have to shift to props that do not have the nut as an integral part of the prop, such as though for camera drone like DJI and JYU.

Thanks Vu.

Sometimes you wonder if anyone is listening.
