1. Reference data of the generator: after rectification at 96 revolutions per minute, approximately 12V DC is output.2. After 192 revolutions per minute, approximately 24V direct current is output.3. After 384 revolutions per minute, approximately 48V DC is output. After 960 revolutions per minute, approximately 120V DC is output.4. After 2400 revolutions per minute, approximately 300V direct current is output.5. The output of the motor increases by 1 Volt every 8 revolutions. The faster the rotating speed, the higher the voltage.
