4 Max motor spec?

[SIMON CRAGG]

In the process of purchasing a 5055 - 595 from 4 Max.

58amps, but no watts mentioned in the spec.

Anybody any idea please?

Generally speaking 58A x however many volts you will run it on - within reasonable voltage limits! Assuming it's listed as 4-6S then you can assume that it will be good for 1300 or so watts. I've certainly found my HK supplied SK3 5055 430s good for an easy 1300W on 6S. Don't forget it all depends on available cooling, how much time is spent at or near full throttle (for most mortals that will probably be <25%) so use these figures as a rough guide only!

1500W max on Hobbyking Simon

The spec suggests 5s to 8s Lipo, so with a max amps of 58 the watts will depend on the voltage you pick.

With a weight of 303gms I would suggest keeping the power to no more than 900watts until you see how warm it gets in flight. Not a scientific figure, just a reasonable rule of thumb.

Just times the max amps with the lipo nominal voltage and that will give you the max watts on that battery.

So on an 8s the max watts is 58 x 3.7 x 8 = 1700 watts, on a 6s = 1280 watts.

It's not watts that damage a motor but the amps which is why it is better to quote them maximum amps as that doesn't change regardless of the supply volts.
