can you use the ice charger as a motor dyno as well ???

dakrat

no

serpentrush

oh ok then thanks

the duratrax ice intellipeak charger have a motor tester i use it alot to find out how my motor is driving

How do you test your motor with the ICE?

dakrat

it dont mean anything. it just shows u how much amps the motor is getting.

Rasmus TbEvo IV

yes and that tells you wich motor is in best condition and i had alot of motor parts and a amature from a motor i tryed putting some of the stuff together. and then testing the amps and it worked alot better after that

The amperage a motor pulls at no load has little to do with how it will perform on the track. A motor that pulls 7 amps can perform just as well, if not better than a motor that pulls 10 amps.

serpentrush,
The motor break-in feature on the ICE helps to determine how many amps your motor is "pulling" from the ICE. If the brushes are seated well on the comm, and the comm is round, generally speaking, the motor will pull more amps from the ICE. This can be used as a "rough estimate" to see if it's time to cut the comm, clean the motor, and/or install new brushes.

Keep in mind, this is not a dyno though. This does not give you how much power your motor is generating. In fact, if you grab a hold of the motor axle, during the test, you'll see the amps go up.

But for the most part, with no load, you can use this as a quick test to see if your motor is in good shape.

Set your break-in voltage to be 3.0V. You should see anywhere from 2 amps to 10+ amps. More is generally better. (If it goes over 10 amps, the ICE will stop the test since it thinks something is wrong.) Most motors properly tuned (or new) will be over 5 amps. The average motor I've tested will be 5-7 amps range.

One motor example: I ran a P2K2 motor about 40-50 runs and it fell to 2 amps. The motor was performing badly on the track. After a comm cut, cleaning, new brushes, and break in, it went to 6 amps, and the motor performed much better on the track. So as you can see, this amp draw number can give you a quick idea of the condition it's in.

Now if only there were some inexpensive load dynos for sale... that would rule.

higher isn't always better...with the low IR of the latest generation cells a slightly lower amp draw has helped keep theheat of the motors down slightly to keep the motor from going soft in the middle of your run..

james thanks for your help will play around with it over w end
