The key innovation in the cascade linear drives is a proprietary gearbox technology that converts rotational to linear motion. The cascade gearbox is a compact and powerful device with several small gears and steps, enabling a high gear ratio and a possible high linear speed.
The cascade technology originates from the wave power company CorPower Ocean AB and the first invention was made by M.D. Stig Lundbäck in 2009. The gearbox technology has since been developed and optimized by the CorPower team.
