Default 6 and 8 poles 1/8 buggy motors

Hello,

just discovered Tenshock brand with their 6 poles motors.

What does it change compared to a standard 4 pole motor?

Are there other brands making motors with more poles? Thanks

they offer a different torque band, and are usually higher quality/much more expensive...


90% of 1/8 e racers can't tell the difference between a wye/delta wound motor, much less a 4/6/8/10 pole motor...

Tenshock isn't more expensive than Tekin .

Not noticing the difference doesn't mean the car desn't run more efficient on the track . Is there a difference of range between 4 ou 6 poles motor? What is the plus of running a 6 poles motor then? When is the torque delivered?

This is true, but the car/running equipment will notice, at least in theory.

Should be able to run a wider range of gearing + higher efficiency, yea?

A (very) rough way of looking at it would be to say a 2 pole motor has twice the RPM and half the torque of a similarly wound 4 pole motor.

So you gain torque and loose rpm when you go up in poles, ok. Now is a 6 poles smoother than a 4 poles running the same kv?

I drive 1/10 and try to look for a setup in 1/8 that would be simiilar in smoothness (lol). It will never be the same but you know what I mean

If you geared them the same and ran the same voltage, the 4 pole would be 'smoother' than the 6 pole because of the decreased torque.

Smoothness in 8th scale really comes down to the esc. I find the closest setup to 10th scale smoothest in 8th scale is the Tekin rx8 and 1700 to 1900 kv 4 pole motors.

Ok then I prefer the smoother feeling . Would it be possible to have a 6 poles motor that is as smooth as a 4 pole by just changing the pinion? Or should I go down in kv?

Sorry for all the questions but it's kind of hard to find these answers on the web.

If you wanted to smooth out the 6 pole you should go down in kv and gear up.

I had a RX8 and T8 1400kv motor on 6S but was just a little bit not smooth enough for me . I love the feeling of 1/10 motors since I switched from the 1/8. This is one of the main reason with the fast corner speed why I moved to 1/10 (I have more pleasure to drive it). Still I love the scale in 1/8 so I try to figure out how to make them smoother feeling/ lighter/ faster in the corners. I almost got there with a lightened 808 on MMP and SC4X 550 motor but it just wasn't powerful enough for bigger tracks (I ran it indoor)

Default Poles

Doesn't more poles work the ESC harder? I am thinking of running a Plettenburg shadow in a sct . I'll probably have to gear up though.

You're comparing many more factors than just the motor between 1/8 and 1/10. The 1/8 car is 2.5x heavier. To power it adequately smoothness will drop down the list of attributes. A 1/10 car is practically weightless under it's power by comparison, ie. the power system is far less stressed.

6 poles motors? Tenshock? I have seen Sct 4x4 n 1/8 Ep wheelie in that setup. Not very good for racing. Too much torque!
