Abstract
Conventional electromagnetic contact-drive systems suffer from the disadvantage that resonant oscillation cannot be obtained, and this is shown in the analysis included. A scheme which overcomes this defect by the use of a permanent magnet and a tuned drive circuit is described. The drive power efficiency is shown to be greatly increased or alternatively for a given power input greater amplitudes of oscillation are obtained.
