What to expect from motor upgrade

How-Tos & Esk8 mechanics

As said above I’m looking into new motors, not that I wanna buy one, but was wondering what I can expect from buying said motor. Bear in mind I just assume for now the ratings are true.
My battery is 14s4p 403.2Wh

Im currently using 2*250w hub motors

The hubs I found 2*450w (I choose those because they have the same “fitting” for pu sleeves

I know there is no Kv rating and the information is sparse but what changes can I expect from getting more wattage? Torque, range, speed etc

Also anything I need to consider if I change my hubs to more wattage

Thanks in advance and to those who saw my battery post, I will buy a new battery first for sure :wink:

If you can’t change settings in the esc, bigger motors will not change anything.

Well that sort ends this thread thanks😅
Except someone knows how to program ling yi Esc with st link

Bigger motors should run cooler or at least have more mass to soak up the heat but that depends on why there bigger and how hot the old ones got

Yeah true but bigger motors are also a little less efficient, so if you don’t change settings you’ll probably end up worse off

With all other things being equal (KV, ESC power limit, etc), bigger motors will run cooler, and that’s about it.

Depending how close the original small motors are to saturation, you may see some slight improvements in torque and efficiency, but it’d be minor.

Yes and no. if you running you motor to the max and hot a larger motor will be more efficient. If you not useing the full potenchal of a small motor because the setting limit it then a larger motor is less efficient. All depends on the balance of the system components.

Not only this, but motor ratings are useless and the only way to really test motor power is to test them IRL. 250W vs 400W means nothing on these chinese hubs. By my own experience, in order of least to most powerful, the 90/97mm hub by power from chinese vendors that i’ve tried are along the lines of

I think my board uses the cdm 2016 hubs, well at least they look exactly the same

2015 huh? I’ve been riding with a 6 year old set of hubs jeez

You can kinda thank these hubs for the existence of most of the industry, they as well as the original ying li ESC opened up massive exports of boards from china and big investment into companies which lead to the entire budget board and chinese ESC industries :slight_smile: We’d probably still only have evolve and boosted if it weren’t for them
