GEARS & GEARBOXES
reliable and sustainable solution for electric marine propulsion systems of all sizes, whether the power requirement is kilowatts or multi-megawatts. For the rail industry, its high-torque to
low-size ratio gives designers greater flexibility, while ensuring torques are at appropriate speeds for the direct drive of vehicle wheels, even within the limited space of a wheel hub. Its design can also withstand the shock loads of wheel hub applications. What’s more, by removing mechanical gear stages, efficiency and reliability are increased and maintenance
requirements are reduced. Another area where the PDD can play a significant role is in the renewable energy
highest torque density motor for electric actuation systems, while its magnetic gear can function as a passively resettable torque fuse, eradicating the need for a clutch or shear pins in case of jamming. With a torque density of >30Nm/kg, these lightweight motors can also be of benefit to the aerospace electric propulsion sector. Furthermore, the technology has potential
for commercial and military marine use, with PDD thrusters providing an efficient,
sector. When used in wind turbines, a PDD generator can provide savings from increased efficiency whilst reducing the cost of installation, decommissioning and maintenance. In tidal current generators, its compact size helps to reduce flow restriction while increasing the system’s hydrodynamic efficiency, providing greater power output at lower cost points. Additionally, the PDD also has potential
in various other areas, including energy efficiency projects, micromobility, industrial motors and hybrid vehicles.
