ERH INDIA 9V DC Dynamo Motor for Science Projects, High Power Dynamo Motor, Power Generator 2 PCs

Works fine new one

All motors working, although a little high rpm which causes need to rotate it faster to generate electricity. In my setup it was generating about 10v without load but decreased with load, but I think that might be my setup's problem. But still low rpm motor with high voltage and current generating dynamo will be more valued. Or you can include some kind of gearbox and gears system compatible with the motor.

First it was not working now its working with battery

The motors i recieved aren't working at allAs the product is 9v dc motor i connected those with a verified 9v batter though its not working .Its quite harsh that defected products are delivered
