How to winding brushless motor

Hello all

First, sorry for my english

I have a motor as on the pics it is a stator TRW power stering pump motor has 12 rotor slots 7 magnets.

The stator is wound in such a way that it has 8 pins.

I want to wind it like a standard brushless motor and use it for my bike

Power from this controller

Can you connect in the current winding?

If not how to scroll it?

what wire

how many turns

Thank you all for your help

A BLDC motor has to have an even number of magnetic poles, so "7 magnets" is a bit weird.

My guess is that each of those 7 segments is magnetised with 2 poles on the same face similar to those used in the actuator motors in hard disk drives.

That would make your motor a 12N 14P motor which are very common, and there are many online guides to winding them.

eg. This one.

Well, maybe I did not think about it.

How to wire up to get out of it as much power but to not overheat it and not burn it

How would I make 18 threads with 1mm wire would it be good?


I need to wind up to get 350-400 kV


maybe that's? https://www.youtube.com/watch?v=-sIVpOLYoqg

I have a choice of a lot of wire and Litz Wire
