Drive Device with an Input Shaft and an Output Shaft Particularly for Driving a Contact Piece of an Electrical Switching Device

摘要

A drive device has a rotatable driving shaft and a driven shaft. The driving shaft, or input shaft, and the driven shaft, or output shaft, are joined to each other by way of a magnetic coupling. The driven shaft can be blocked in a direction of rotation such that magnetic forces emanating from the magnetic coupling cause the driven shaft to move in a direction opposite that of the direction of blocking. The driven shaft moves in a springing manner.
