220V Double Ball Bearing Mute Inner Rotor Drive Motor DIY High Voltage Generator The tail of the 775 motor can be connected to a 12v Batteries or other power supply to generate electricity Please note: The electricity sent out can only be small power. This generator is mainly because the current is not large and cannot be used with household appliances. There is no problem with charging the light bulb for mobile phones. The magnetism of the rotor is very good, but because it is a brushless motor and has double ball bearings, the shaft of the motor turns lighter than a brushed motor. That's why it is more suitable for DIY into a generator.
