how long a motor can last

I am using an atomic stock r motor, I think I used it for 10 times, around 4 hours each time, and I use LiFe battery. Recently I feel it not as fast as before. I guess it is due to the battery, but today I tried a new pack, seem no improvement.... I wonder, does motor has a lifespan? If so how long it normally last?

MINI-Z用有刷摩打, 用得耐個刷會蝕, 要換刷, 或者換新摩打,

之前有師兄文章教維修摩打, 麻請自行爬爬文章.

我都係MINI-Z新玩家, 玩左幾次, 所以未清楚MINI-Z既摩打壽命.

A motor could last for years if you service it regularly

百零二百排電到啦，無話用幾多個月，or幾多年既~

    亨利兄,我已經超越百零二百排電,
直至有刷變無刷為止,都唔記得玩左幾很耐

我o個粒都玩左.. mmmmm.. 2年以上, 但係都只不過百零排齡

thx chings, after changing the brush it become as fast as when it is new, thanks for the tips
