Venquessa and vegasbs, thanks for the explanation. I've been googling and reading a lot and understand what you are saying, I see how the loads may be focused on one winding only at 1/3 throttle instead of spreading the load to all windings, very interesting.
Where I am going off of the tracks is with this example.
I'm looking at this Turnigy Motor
Dimension: 36mm x 51mm, 70mm(with shaft)
Weight: 181g (kv1450) (not including connectors)
Diameter of shaft:?strong>F5mm
Length of front shaft:?strong>F19.1mm
Lamination thickness: .2mm
Magnet type: 45SH
No. of cells: 3-6S
Max efficiency current: 45A-50A
No load current: 11.1/4.6A
Current capacity: 70A/20sec
Internal resistance: 0.010ohm
Prop: 7x5, EDF90
For EDF 1500~1800g model airplane.
Kv (rpm/v) 1450
Weight (g) 181
Max Current (A) 50
Resistance (mh) 0
Max Voltage (V) 22
Shaft A (mm) 5
Length B (mm) 51
Diameter C (mm) 37
Can Length D (mm) 30
Total Length E (mm) 70
The motor states it can take 1600 watts. If I deliver 22V (6S) and 50Amps (max rated), I am only delivering 1100watts. How would I ever get to 1600 watts without exceeding a limit??
People using this motor are reporting pushing this motor to 1597 watts but it takes 92amps. Are they vastly overamping the motor?? THANKS AGAIN!!
