Team Power Brushless Motor Checker

As I heard from the TP motor checker manufacturer, the usage of lipo battery in the TP checker because the lipo battery output voltage is quite steady with a sudden high current drawn by the motor. Also, the lipo can provide a constant voltage curve for a period of time and this is the reason why it is commonly to use the lipo in most RC model car today, so the lipo battery can provide a stable source to the checker and make the output results more consistence.

The Kv reading will be unaffected by the drop in voltage so that will allow you to compare any motor to previous tests even with a half charged pack. if the system is any good it will have a "soft start up" to eliminate huge current draw with low turn motors. This is a nessesatiy if you are going to use aligator clips like those in the pics anyway. High current would most likely melt them or make the very hot real quick.

In IIC race, there is a TP checker to have demo. I see there are 8 power levels LED on top of the checker. At the start of running, it is default to set as power level 3 and it can use up, down key to increase the power level, so I think it can prevent a huge current drawn by the motor from the start up on the lower start up power level.

good news!

It's no good asking about Kv ratings as they prove nothing.
As is mentioned everytime a motor checking thread appears, rev's without torque is useless and you can't check torque without putting a load on the motor.
It will have less variables than when we were testing brushed motors but there will still be inaccuracies.

yes. the measured result will be more accurate if any loading can on the motor. However, this kind of motor checker can allow anyone to check and compare different brand or same brand of BL motors with the same platform. At least the user can know which one is better at the same platform and if the motor is healthy or not. One more important note, I found the ampere reading shown on the checker that can really reflect the punch power to the rc car. In other words, for high ampere reading for the motor which can have more punch power!!

any one have comment on it?

Charlie b, I thought the same thing too regarding using a power supply. But if my mind serves me right, wouldn't a high amp draw be needed sometimes like much over 30 amps? I know that these lipos can handle quite a bit of amp draw and maybe that is why they are using a 2 cell lipo........
Then again, maybe amp draw would not be a problem since there is no load from what I can see.
Just my .02 cents.....and thoughts
