Currently, we have tested several brushless motors and now need to work on the exact specifications for a custom design. We have extrapolated requirements from smaller test motors (the speed controllers of these motors log critical data so we have a lot of information available) and are about to test our latest.
Using some of the advanced technology from the RC community we have a motor with the following specs:
10 kw continuous power with 20 kw surge
Weight 6.0 lbs Height 4.5" Length 3.5"
10,000 RPM max geared down to 4:1
Kv 117
Max volts 85
We run this motor with 4 4s LiPo in series (16 total)
In early tests we can see we are drawing > 300 Amps but measuring torque is proving difficult. (> 175 NM)
Question 1: It works for our application but how can we optimize efficiency? So far it has been trial and error (and error is getting expensive). Ideally we would like this motor to be in a pancake configuration
Question 2: How can we find an engineer to add to our team? We are a two person startup with some very promising new technology (patents applications are in the PTO).
Thanks in advance,
