Scientists of Forschungszentrum Jülich have developed an innovative actuator concept offering double-acting linear movement without friction and without lubrication. This technology is particularly suitable for use in extreme environments and has been implemented as a linear motor for a shutter and as a linear drive for a sensor in an ITER experiment. The linear drive can be used as a servomotor for an orifice plate / shutter release or as drive mechanism for a sensor movement and could be suitable for use with different fluids, i.e. gases or even liquids in many industrial applications.
