Due to the large torque density of magnetic gears(MGs), magnetic-geared permanent magnet machines(MGPMs) have become promising competitors in the family of direct-drive machines. According to the deployment of armature stators, MGPMs can be generally classified into three types, viz., MGPM with inne...

In this paper, an outer-rotor parallel-hybrid-excited vernier machine is proposed. In order to realize the parallel hybrid excitation, the homopolar configuration is adopted to artfully combine the permanent magnet (PM) flux path and the electromagnet flux path together. Firstly, the structure of th...

Availability is an important factor to be considered when designing wind turbine generator systems. The quest for increased availability is based on the following five design approaches - design for component reliability, active control for reliability, design for fault tolerance, prognostics...

The movement of waves propagating over a horizontally submerged perforated plate with waterfilled chambers bellow the plate was investigated by using linear potential theory. The analytical solution was compared with laboratory experiments on wave blocking. The analysis of the wave energy dissipatio...
