How does a resonant SQUIGGLE drive work?
A series resonant tank circuit is created by adding an inductor to the output of the SQUIGGLE driver. The electrical resonance of the tank circuit is tuned to exactly match the SQUIGGLE motors mechanical resonance. In this way, high voltage drive signals can be applied to the SQUIGGLE motor phases with much lower input voltage and higher efficiency operation. Control and drive techniques used for direct drive also apply to the resonant drive method.

The electrical resonance of the tank circuit is “tuned” to exactly match the SQUIGGLE motor’s mechanical resonance.
