Rewind Freewing 2845-3000

Regularly called 2845-3000, this motor has a label that identifies it as 2826-3000. and it is accompanied as an up-grade for any EDF of 5 and 6 blades of 70mm. which brings a 2839-2750 motor of 87 grams of weight and is used in an approximate of 500 W.

to an edf of 8 blades. and which consumes 1000 watts with 4 slipo.

Changing an motor that consumes around 500 watts to one of 1000, is a good increase in weight in the motor.
Actually this motor only weighs 99.5 grams vs 87 grams of the one it replaces.

By increasing 13 grams of weight in the motor and charging it up to 1000 watts, it only makes it an extremely inefficient motor.

at 14.6 volts, 69.6A, 32,869 rpm for u Kv Effy of only 75%.

The plan is to change the kv to approximately 2720 so that it only consumes about 800 watts. a more appropriate amount for the motor.

Is that a six magnet motor? They must do that to keep the permutation rate down some on those higher Kv motors.

I am working very slowly with this motor.
Work has not given time.
I have to to make a new tool to remove the stator.
And I could not rewind it with the base set in the stator.
