PIEZOELECTRIC STEPPING MOTOR Russian patent published in 2000 - IPC

FIELD: piezoelectric actuating motors. SUBSTANCE: motor has frame incorporating locking assemblies and moving part. Locking assemblies are made of at least two revolving, displacing, and locking piezoelectric blocks arranged lengthwise in tandem within frame. Each piezoelectric block is made of revolving piezoid, displacement piezoid, locking piezoid, and frictional member with insulators in-between. Spaces between piezoids are filled with plastic insulating material. EFFECT: simplified design, facilitated manufacture, enhanced force, and improved precision of positioning. 14 dwg
