ESC Setting up a YEP

[trainrider06]

Hey all I am setting up a YEP esc on the program card have the 500MX 1600kv motor, I think its a 6 pole from what i have read. Down on the PWM frequency setting I take my motor KV 1600 X battery cells X poles (6) divided by 20 and get 2,880. The card however only reads to 16 kHz....do I just set that to that or am I missing something???

Wouldn't that setting be 2.8kHz?

If you are running 6cell, then the formula is.
1600 x 22.2 x 6 / 20 = 10656
So you PWM would be 10kHz

Shows how long it's been since I did that lmao.

Lol yeah I had one of those slap your head moments last night when I realized it was KV X the actual voltage of the battery!
Duuuuuhhhh! Thanks Lee, Tony!
Although now my motor and ESC are getting hot. Should I lower the motor timming or something? It's on 18 I think right now.

 

[Tony]

I would, 18 is pretty high.

Low pole count motors require a lower timing.
Poles are the number of magnets in the motor, not the number of stator arms. (just to clarify)
On the program card set the PWM to 10 and the Timing to 6º.
If 6º doesn't make the motor hot, then you could try 12º, but i think 6º should be good.

Ok Thank you Lee will try that!
