PIEZOELECTRIC STEPPING MOTOR Russian patent published in 2001 - IPC

FIELD: actuating mechanisms in electrical engineering, telemechanics, etc. SUBSTANCE: motor has frame accommodating locking assemblies and moving part. Locking assemblies have at least two shifting-and-locking piezoelectric unit and revolving-and-locking one arranged in longitudinal plane in tandem or in transversal plane. Shifting- and-locking unit has interconnected shifting and locking piezoids, insulators, and frictional member; revolving-and-locking piezoelectric unit has interconnected revolving and locking piezoids, insulators, and frictional member. Piezoelectric units arranged in transversal plane are sector-shaped. EFFECT: simplified design facilitated manufacture, enhanced positioning force and precision. 3 cl, 16 dwg
