Linear drive device of high power and mass density with simplified structure

摘要

Linear drive device of high power and mass density with simplified structure, comprehensivea power source for the supply of a power supply; anda drive force conversion module (6), which is rotatable with the drive source,characterised by the fact that the power source is an outboard motor comprising a stationary system with an iron core and a winding and a rotating system based on the stationary system, whereby:the drive force conversion module (6) includes a ball -spindle nut fixed to the rotating arrangement (4) and a ball -spindle adjusted to the ball -spindle nut (4) spirally -shaped (3); andthe rotating arrangement is a hollow -shaft structure on which the ball spindle (3) is mounted.
