Blue Printing Your Motor
by Mick A & Tyson Jyoce
Part II

Taking the motor apart and installing the Magnahone Brush Tool to radius the motor brushes right inside the endbell to get the most accurate brush radius.
Before installing the motor brushes to be radiused they are marked left and right so they will be installed back the same way they were radiused
Installing the motor brush to be radiused, check that the brush slides in and out with out no hang ups.
With both motor brushes and motor springs installed, add a tire or a cordless drill to turn the Magnahone Brush Tool to radius the motor brushes.
After radiusing the motor brushes it's time to clean them up. Use a Q-Tip to remove the motor brush dust.
Before and after shot of the motor brushes. Noticed the brush on the right has been radiused all the way to the edges as to make breaking in of the motor a lot faster.
Making sure that there is no hang up on the motor brushes Tyson checks to see if the motor brush falls in and out on its own.
Since this is a Twistor Motor (Parma Rotor motor will do the same job), the timing is twisted up by twisting the endbell clock wise or away from you to crank the timing up!
Allready to break it in, motor is oiled with JK Glidex oil.
Break in time! Using a Wright Way Power supply the motor is broken in at 4 volts for approx. 5-8 min.
And there you have it! That was a basic blue printing of a motor which can be applied to any D or C-can motor. You can get into more detail such as magnet matching, soldering in the can oilite, com cutting, etc., but we just wanted to cover the basics of motor building.
