|PCT/CN2012/000743||TSAI, Jui-An||TSAI, Jui-An|
Disclosed is an energy-saving apparatus able to rotate in a semicircle and reset in the reverse direction by virtue of gravitational force, wherein in the first half of a cycle in a cyclical operation, the apparatus firstly controls the rotation of a transmission shaft of a motor rotor, making same drive a first rotary shaft to rotate in one direction by virtue of a first variable-speed gear mechanism and synchronously drive the motor rotor to move from the lowest position up to the highest position along a circle defined with the first rotary shaft as the centre of the circle and a support arm as the radius, thereby accomplishing a semi-circular rotation. Then, when entering the latter half of the cycle, the apparatus controls the transmission shaft of the motor rotor so as to stop rotating, making the motor rotor reset from the highest position to the lowest position by virtue of its own gravitational force, taking the same semi-circular trajectory. In this way, cyclical semi-circular rotation is achieved by the motor rotor, bringing about sustained unidirectional rotation of the first rotary shaft, thus achieving the effect of energy-saving usage.
