介绍了磁力金属带传动的工作原理，分析和探讨了其有效拉力、线速度及弹性滑动率等传动性能，并通过实验测定了相关性能参数。结果表明，磁力金属带传动主要是利用磁场吸引力与初拉力的耦合作用来增加摩擦力进而传递运动和动力的，其传动效率可达95%～98%，而弹性滑动率一般在0.1%以下。

The characteristics of metal belt drive with magnet (MBDM) are introduced in this paper. The transmission characteristics are also analyzed and discussed, such as effective tension, linear velocity and elastic sliding ratio. Finally, some performance parameters involved are determined by experiment. The results show that the friction force between pulley and metal belt can be increased by a great extent because of the coupling action of magnetic attraction and initial tension. The transmission efficiency of MBDM can reach from 95 % to 98 % , but the elastic sliding ratio is usually not more than 0.1%.
