To improve the evaluating ability of the electrical contact properties of the materials, a test device with a good comprehensive performance is designed based on eddy current repulsion mechanism. The working principle, mechanical structure and driving circuit of the device are introduced. A prototype of the device is made and tested. The result shows that the device has a wide range of speed regulation, wide application scope and small volume.
