FIELD: electrical engineering.
SUBSTANCE: wave piezoelectric drive contains a flexible wheel with external gear 1, which engages with the internal gear of housing 2, as well as with the internal gear of output faceplate 3. A pusher system is installed in housing 2, which is connected to flexible wheel 1. The pusher system consists of flexible multipliers 4, in which piezoceramic plates 5 are placed. Operation of a wave piezoelectric drive is carried out by supplying electrical energy to piezoceramic plates.
EFFECT: improved weight and size characteristics, increased reliability.
