Could I get your advice about my choice of motor.
I would like to use a motor to generate electricity when being turned passively and charge batteries like a wind generator. When the wind speed drops below a set point I want to activate the motor to maintain minimum RPM on the fan to function like a cruise control for the wind. I'll use an Arduino with a rotary encoder to measure RPM, control the motor and charging.
Design goals are to generate up to 2A @ 5000RPM for charging batteries, Then be able to run at up to 5000RPM by the motor. The motor should be small, lightweight and inexpensive.
Ideal shape would be flat like a pancake and have low drag when being turned passively. Possibly frame-less.
What motor do you think would work best in this situation?
Thank you, I appreciate your advice
