Yes, racers just want the best. The motor analyzer is to check the equal precision of the 3 sensors, the magic timing value at a certain current and check a before and after rebuild if it did improve or you did do something wrong.

The rotor checker is just to compare and check the condition magnetism of rotors.

Still a killer product. Just used it again to recheck my rotor. Was hoping to test the new Tekin but caught the Vid early this week so can’t test it until the following weekend.

Did you get the Tekin R2?

One question, Will this help in figuring out the best shimming for the rotor in the motor can?

No, it only checks the strength of the magnet outside the housing.

Roelof is correct. This tool only checks the rotor's magnetic strength.

When shimming, there are a few ideas on what is the best way to shim a motor.
  • Shim the rotor to be as close to the sensors as possible so the readings are more accurate.
  • Shim the rotor so it is centered in the middle of the stator. The theory is, this will give it more power.
Whichever way you choose, the main reason for shimming is to allow as little side-to-side slope as possible, with your rotor. Just make sure you don't shim the rotor to be too tight.

Taking into account every motor is different, what is best practice to determine how much play are you looking for. In looking, and talking with people there is seems to be a difference of opinion.

In my opinion, you might want to leave around 1mm of play. The just about all materials expand when they get hotter, so you might want to leave enough room for that. As for too much play, this could cause erratic reading between the sensor points. Is it going to make that much of a difference? Well, many racers will spend hundreds of dollars to make their car go 0.5 seconds faster around a track. To those looking for all the juice they can get, shimming will be an option.

Every motor is different, but they all work off the same principle. IMHO, efficiency is the main goal. Slop, in a rotor, will take away some of that efficiency. With all the different motor brands, I have shimmed, they all responded the best when shimmed with about 1mm of slop.
