Abstract

An electricity generation device with low power consumption has an operating module, a first motor, and a second motor. The electricity is inputted to the first motor to actuate the first motor in a short time, the first motor drives a transmission assembly of the operating module to rotate, and the transmission assembly drives a flywheel of the operating module to rotate. A generator rotor is mounted around the flywheel, and a generator stator is mounted around an inner peripheral surface of the body. The second motor is driven by the transmission assembly. When the flywheel reaches a certain rotational speed, the second motor only needs a low current input to keep operating. That is, the second motor can be continuously operated, and the flywheel generates rotor power, thereby achieving power generation at low energy consumption.
