The latest version replaces the original SQUIGGLE motor’s monolithic piezoelectric elements with advanced multi-layer piezoelectric elements from TDK-EPC to achieve the reduced operating voltage. The NSD-2101 drive circuit was developed in partnership with ams using New Scale’s control algorithms to increase motor efficiency and refine the motor control capabilities.
U.S. patent # 8,217,553 was issued July 10, 2012 to inventors Qin Xu, David Henderson and Daniele Piazza.
