Wave energy is a source of renewable energy that converts the slow oscillating motion of sea waves into electricity. One of the many challenges to this immature technology is the development of a power take off which must take variable velocity slow oscillatory motion and convert it into fixed frequency electrical power. The Blue Star wave energy device floats on the sea surface and consists of two floats separated by a hinge. In this paper a Vernier Hybrid Machine is developed for use as the power take of in the Blue Star wave energy converter. Firstly, the topology and operation are presented, a short design study conducted to assess the impact of rotor tooth and magnet geometry. The process of developing a prototype is described, detailing the benefits and complexities of modular manufacture. FEA simulations are validated against the experimental prototype and analysed. Finally, design options to further optimise the machine are given.
