SINGLE-PHASE STEPPING MOTOR Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: single-phase stepping motor is intended for discrete electric drives. Presence of two working gaps placed with axial displacement enhances reliability and accuracy of step execution. Magnetic core of stator is symmetric in three perpendicular planes and presents rod split in two and located inside hollow rotor 7 having two groups 9, 10 of teeth displaced axially. EFFECT: simplified design of motor thanks to reduced number of component parts, simplified manufacturing technology because of diminished number of component parts of magnetic system. 3 dwg
