Default Team Much More Motor Master Platinum Edition

Hi Guys,

I am wondering if anyone knows how the "Team Much More Motor Master Platinum Edition" works when testing a motor.

I know it does RPM, but i don't know what the the AMP draw etc readings are suppose to represent.

Example: I was testing a 540 motor and it said it was doing 19000 RPM, considering most of the motors do around the 17000 RPM, i thought this would be a good motor. The problem i could see was that it had no torque.

I have a Team Much More Motor Master Platinum Edition, but i am now not sure how to read what is a good motor and what is not a good motor.

Any one have any ideas??

regards

you are right with the rpm, the more the better... usually

the amps is how much current the motor draws to spin at the given rpm, so the less amps it draws, the more torque it has theoretically.

but sometimes, you cant tell the difference between a dead motor and a rocket motor until you put it in the car and run it around the track...

You should be looking for something around 2.25A @ 15000 rpm, then you will have
a decent motor wich will not draw too much curent.If you can't do it contact Doc, he is the man for those motors!

here is the link for the manual of your motor checker:

Have a nice day!

Well, I know a little.

Generally speaking, the only valuable number you get from the motor checker is the RPM at 5 volts. Forget the reading at any other voltage.

Amp draw at any voltage is an unreliable predictor of torque or any other performance variable, because many things can cause a nominally higher amp draw (dirty comm, something stuck in themotor, tight bushings). That's why we use both a motor checker to test RPM and a dyno to test torque and power curve.

The motor checker is a good tool, but best used for portable work when you just want to know if your motor is going sour or needs to be cleaned.
