LINE STEPPING MOTOR Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: line stepping motor is designed for electric drives. In proposed motor piezoelements are inserted instead of system of excitation winding on poles and system of their commutation. They are placed between groups of poles 3 with equal shift over teeth grooving and cover 2. Groups of poles 3 are mounted in bottom 5 of armature frame for vertical movement of armature frame. EFFECT: simplified design and increased speed of response. 2 cl, 6 dwg
