Abstract: A work output device is revealed. The work output device includes two motor rotors respectively arrange at two ends of a horizontal main rotating shaft. An outer transmission shaft of each motor rotor starts rotating after the power is turned on. The rotating outer transmission shaft drives the main rotating shaft to rotate in one direction through a speed change gear mechanism. The motor rotors are synchronously driven to rotate around the main rotating shaft and move from a lower position to a higher position. At the moment, the power is turned off and the motor rotors turn back from the higher position to the lower position with the help of gravity. Thus a cycle of repetitive up-and-down half circle rotation is completed. Moreover, the main rotating shaft drives a work output shaft to rotate by a torque controller.

Abstract: An energy saving device rotating a half circle and turning back with the help of gravity is revealed. In the first half cycle of a circle movement, a transmission shaft of a motor rotor is controlled to rotate and further drive a first rotating shaft rotating in one direction by a first speed change gear mechanism. The transmission shaft synchronously drives the motor rotor to rotate a half circle, from a lowest position to a highest position on a circumference of the circle. In the other half cycle, the transmission shaft of the motor rotor stops rotating and the motor rotor returns from the highest position to the lowest position with the help of gravity. Thus the half circle rotation of the motor rotor is completed and the first rotating shaft is driven to rotate in one direction continuously so as to achieve energy saving effect.
