Abstract：This paper proposes a novel rolling-type generator mechanism for the Salter-Cam wave energy device. The generator mechanism can convert the bi-directional rolling motion into uni-directional high-speed rotation and drive the generator to generate electricity. This paper tests the performance of the prototype of the proposed generator mechanism and analyzes the measured data. During the experiments, the time histories of the input mechanical torque, angular velocity, output voltage, and output electric current were measured. Firstly, based on the information, the power generation efficiencies are calculated under various working conditions. Then, the influences of the rolling amplitude and rolling period on the power generation efficiency of the generator mechanism are investigated. The obtained results indicate that the proposed generator mechanism can generate electricity stably. This work proves the effectiveness of the design. At the same time, it reveals its drawbacks and points out the improvement direction.
