Re: Motor Comparison Chart
Also, I can't remember the last time I cared about free current.
It matters most if you are doing some sort of inferred sensing (e.g. I don't have a speed sensor and I want to estimate speed or torque buy measuring current and voltage -- in this case the free current is needed to model the motor correctly). Very nice data from Vexpro by the way. Thanks for pointing this out. Hold Strong, Dr. Joe J. |

Re: Motor Comparison Chart
I think the most valuable data is the 3 minute max power and the stall torque curves. Pretty interesting that the "high power" 775s lose to mini-CIMs after just 10 seconds. They probably lose even faster if you're accidentally on the wrong side of peak power.

Re: Motor Comparison Chart
Why do 775 Pros drop max power so suddenly?

Re: Motor Comparison Chart
The 775Pro's are intended for shooters and such, where they can run at high rpm. They are fan cooled, so if they stall they fry in 4 seconds.
