However, you might have to TAKE AWAY THE BRUSHES FIRST before you are able to check whether the armature stays at the centre of the magnetic field, which is not very convenient when you are using conventional motor cans.

Here are three ways to adjust the position of the armature to fit different motor cans. (CLICK TO ENLARGE) See if you have other ways.

I see, and what motor case and Magnet will you use on this one?

this is very interesting topic, it could be more helpful if Ching can explain the relations and secrets between the:

I only use 3 kinds of magnets: from strong to weak :silver thin magnets, plasma dash (tamiya) and magnets from kit motor.

Thin silver goes with anything lower than 40-turn.
Kit motor magnets go with a rotor of 60 and higher turn.
For something in the middle, around 40-60-turn, I use the plasma dash (black) magnets.

Note that magnets die easily when the temperature is high. When they are weakened, the temperature becomes even higher while the motor runs more slowly.

開正你個番呀暴暴!

Thanks for the info. can't wait to see the final figures..
but how about the N and S pole of the magnets, does it matters if I swap the poles, or how do I identify N or S poles?
how about the brushs' positions??
sorry I got a lot of questions, I'm just a new guy to this stuffs...Thanks

Very useful information and I will try it sometime

利害啊。

不過，我仲未買到漆皮線。因為，上次去買既時間唔啱，佢地趕住收工。仲有，佢現貨 D Size 古古怪怪咁。一係就要訂。

我諗住遲ｄ再去行下，睇下有無第二間。

我今日買左一卷 #29,  買左 1lb

This is how I find out the heavier side of an armature in order to balance it. The heavier side always goes to the bottom.

我搞噶...卑D意见.未做平衡.

點解有 d 銅線深色 d,有 d 淺色d,有咩分別呢?

To what I've experienced, colour doesn't matter. What you see is the colour of the coating. All you have to watch out is its thickness.
