Electrical Question
 
OK I have a Question about a electric motor I have. The Specs on the motor state

24V 2600R/Min
Rated Current 22A
350 Watts

What I am trying to figure out is Rated current. Does this mean what the motor will draw at a stall? or is it what is needs to produce 2600 RPM at 24V for 1 HR? If watts is Volts X Amps than I should be at 528 Watts. But if I Devide 350 by 24 I get 14.58 Is my motor drawing 14 amps rather than 22?

I read some place that Motor specs are usally 25% higher than actual tested ratings.....I don't know I am not real good with Electrical. Mechanical is more my thing. I am just trying to find this out so I can look for a controller that is rated properly....Thanks Guys

These are maximums. A motor curve is more representative (Mabuchi has curves for all their motors on their site).

The 22A is locked rotor before it burns up literally!;)

The wattage is a max power over extended time.

The ESC does not have to deliver this full load to be effective, this is more showing what size ESC it can stand before burning up.
