| 摘要 |
The invention refers to an electromagnetic force device arranged to provide a force, a shock absorber with such a force device, a scale with such a force device, a sewing machine with such a force device and a handling device with such a force device. The force device includes an elongated holder element ( 1 ), a first magnet element ( 2 ), which is connected to the elongated holder element ( 1 ) in such a way stationary in relation to the holder element, a second magnet element ( 3 ), which is slidably connected to the elongated holder element ( 1 ) in such a way that it is displaceable along the holder element towards and away from the first magnet element ( 2 ). At least one of said magnet elements ( 2, 3 ) includes an electromagnet. An effect unit ( 10 ) is arranged to provide an electric effect to said electromagnet for generating a force in a first direction.
