Number of Poles On T-Motor 2216

I have a faint recollection that there’s something different about the number of poles on the T-Motor 2216 motor.

When I look from the bottom of the case and count the magnets, there appears to be 14 - just as one might expect.

For some strange reason, eCalc shows that the number of magnets for motor is 10.

I can’t find a data sheet for this motor anywhere.

I’m having a little trouble with this motor and AM32 firmware. The AM32 firmware configuration needs to know the number of poles - and is set to 14 - perhaps a default.

I know a lot of people have used this motor - and I have a faint recollection of this question coming up for me a long time ago.

If anyone knows of some specifics, I’d appreciate the help. Thanks!

I was going to suggest verifying the pole count on your topic regarding misbehavior of this copter. Seems a logical place to start. I do not have any more info about that motor combo, though.

I have one of the Hexsoon branded versions of that motor handy and it’s 14. If that helps…

Thank you @Yuri_Rage and @Allister - Yes it the motor does seem to have 14 poles.

I’ve been chasing down a problem with my first AM32 ESC that caused the motors to violently vibrate on the workbench without props doing a motor runup in stabilize.

I found out this afternoon that the problem was with option called Complementary PWM.

As I read the info I could find, this option should improve motor efficiency - but it requires ESC hardware to work. So I guess mine doesn’t have it.

I think I may stick with BLHeli_32 until AM32 is developed a bit further - with documentation to match.

Complementary PWM is for Dynamic Motor Braking.
