For this project I would like to invite every member of this forum to contribute.
My goal is to evolve an UAV (unmanned aerial vehicle) that my group are developing and try to get more autonomy with the same battery set that is running ours Outrunner Brushless motor.
I have good electronic skills, including design and assemble circuit boards using SMD components, which make circuitry smaller and better to embedded applications.
The current motor used at the UAV is an Outrunner Brushless which run a propeller 9x6" (for those whom are not familiarized with this number it represent a propeller with 9" of diameter and pitch of 6", which means the propeller go forward 6" for each revolution)
Outrunner Motor Specifications
Stator Diameter 30.0 mm (1.18 in)
Stator Thickness 20 mm (0.79 in)
No. of Stator Arms 12
Magnet Poles 14
Motor Wind 10 Turn Delta
Motor Wire 14-Strand 0.25mm
Motor Kv 890 RPM / Volt
No-Load Current (IO/10V) 1.42 Amps
Motor Resistance (Rm) 0.020 Ohms
Max Continuous Current 45 Amps
Max Continuous Power 780 Watts
Weight 166 Grams (5.86 oz)
Outside Diameter 37.50 mm (1.47 in)
Shaft Diameter 4.98 mm (0.196 in)
Body Length 45.75 mm (1.80 in)
Overall Shaft Length 74.5 mm (2.93 in)
Max Lipo Cell 5s (18.5V)
Motor Timing 5deg
Drive Frequency 8kHz
My first step is to figure out if Keppe Motor can perform similar workload with acceptable size and weight.
Does anyone have some theory or experience with this kind of development?
