I'm designing a power assisted bicycle for my senior project in mechanical engineering and I have a few questions about the electric side of the design. I want to attach a small motor to be driven by the rear wheel to generate electricity to recharge the battery. The specs of the motor I was looking at are as follows
American Bosch Motor/Generator
-1/3 HP
-24 volt DC
-No-load speed 7800 RPM
-No load amps 1.5
-Full load speed 5900 RPM
-Full load torque 60 oz-in
-Full load amps 15
-Motor body: 2.5" diameter x 4.5" long
-Shaft: .25” diameter x .75”
-flatted on two sides.
-Two 10-32 mounting studs on front, .7” long, on 1.94” centers.
-self-resetting bi-metal thermal protection.
Now my question is, is there a way for me to calculate what kind of current is being generated at a certain rpm? I'm hoping there is a generic formula and its not totally dependent on the motor.
