LINEAR INDUCTION DRIVE Russian patent published in 1995 - IPC

FIELD: robotics; machine-tool drives. SUBSTANCE: linear induction drive has inductor built up of separate cores carrying coils of multiphase winding, electricity conducting secondary element of cylindrical shape, and switching device that connects coils with voltage supply. Switching device is coupled with voltage supply through knife-switch. Coils are connected to voltage supply so that rotating magnetic field is excited while crossing secondary element which rotates and performs stepping motion. EFFECT: improved design. 7 dwg
