- Experimental data is fitted against partial overlap between the stator and the translator to different powers from one to four to see which relations can be found between electric power, copper losses, other losses, and the dampening force. The other losses consist of iron losses and frictional losses together. The results differ depending on whether the translator is moving up or down, especially for the electric power. Why that is would need further studies to explain. The electric power shows mainly a quadratic dependence on partial overlap, but a cubic dependence as well cannot be excluded, especially when the translator is moving down. The copper losses shows aquadratic dependence on partial stator overlap. The other losses show mostly a linear dependence on the partial stator overlap. The dampening force shows mainly a linear dependence on partial overlap, but a quadratic dependence as well cannot be excluded, but this is probably since the electric power and the copper losses affect the dampening force except when there is no load.
