Abstract: An oscillating pendulum-based power generation mechanism of a power generator includes a stator device, a rotor device and a shaft-driving device. The stator device has a stationary base and multiple first magnetic bars mounted on an inner surface of the stationary base. The rotor device has a spindle, multiple pendulum assemblies and multiple second magnetic bars. The spindle is rotatably mounted through the stationary base and is connected with a shaft of the power generator and the shaft-driving device. Each pendulum assembly is connected with the spindle and includes a weight. The second magnetic bars are distributed across the weights of the multiple pendulum assemblies and are identically oblique to the weights and repel the first magnetic bars. The repellant forces between the first magnetic bars and the second magnetic bars allow the pendulum assemblies to be rotated to drive the power generator for power generation.

Abstract: An oscillating pendulum-based power generation mechanism of a power generator includes a stator device and a rotor device. The stator device has a stationary base and multiple first magnetic bars mounted on an inner annular surface of the stationary base. The rotor device has a spindle, multiple pendulum assemblies and multiple second magnetic bars. The spindle is rotatably mounted through the stationary base and is connected with a shaft of the power generator. Each pendulum assembly is connected with the spindle and includes a weight. The second magnetic bars are distributed across the weights of the multiple pendulum assemblies and are identically oblique to the weights and repel the first magnetic bars. The repellant forces between the first magnetic bars and the second magnetic bars allow the pendulum assemblies to be rotated to drive the power generator for power generation.

Abstract: A horizontally rotating driving apparatus is connected with a longitudinal rotating shaft and includes a frame, a rotating unit, multiple electromagnetic units and multiple sensor switch units. The frame is mounted on the rotating shaft and has an inner space formed inside the frame. The rotating unit is located in the inner space of the frame and is horizontally and rotatably mounted on the rotating shaft to form a rotation path. The electromagnetic units are disposed in the inner space of the frame and are arranged along the rotation path of the rotating unit. The sensor switch units are mounted in the frame and are disposed in the inner space of the frame at identical intervals. When one of the magnetic portions passes the sensor switch units, the sensor switch units sequentially control the electromagnetic units to start or to stop generating magnetic force and rotate the rotating unit.

Abstract: A gravity-assisted rotating driving apparatus is connected with a horizontal rotating shaft and includes a frame, a pendulum unit, at least one electromagnetic unit, and at least one sensor switch unit. The frame is mounted on the rotating shaft and has an inner space formed inside the frame. The pendulum unit is located in the inner space of the frame and is rotatably mounted on the rotating shaft to form a rotation path. The at least one electromagnetic unit is disposed in the inner space and is arranged along the rotation path. The at least one sensor switch unit is mounted in the frame and is disposed in the inner space. When the pendulum unit passes the adjacent sensor switch unit, the corresponding sensor switch unit controls the corresponding electromagnetic unit to start or stop generating magnetic force and to rotate the pendulum unit.

Abstract: A fan system including a motor with a coil, a storage unit, a driver, and a buffer circuit is provided. The coil module has a first connection terminal and a second connection terminal. The storage unit electrically couples with a voltage source, stores electrical energy when the voltage source is available, and releases the stored electrical energy to carry out a brake operation when the voltage source is unavailable. The driver electrically couples with the first and second connection terminals of the coil module to control a direction of an inductor current passing through the coil module. The buffer circuit electrically couples with the coil module. In the brake operation, the buffer circuit operates to form a transient potential between the first and second connection terminals of the coil module and to consume electrical energy of the inductor current, for gradually stopping the motor in a buffering time period.
