Abstract
The present invention relates to a linear drive with a stator, a runner, and two rotative drive units provided for driving the runner. It is provided according to the invention that the linear drive comprises two magnetorheological clutches, wherein the first drive unit can be coupled to the runner using a first magnetorheological clutch and the second drive unit can be coupled to the runner using a second magnetorheological clutch. The output torque of the first drive unit acts upon the runner in the opposite direction to the output torque of the second drive unit.
