INDUCTION MOTOR WITH OPEN MAGNETIC CIRCUIT Russian patent published in 1996 - IPC

FIELD: electric engineering. SUBSTANCE: device has inductor, which consists of core 1 and three-phase winding 2, and secondary unit, which consists of core 3 and winding, which rods 4 are short- circuited by common line 5 on one side and by short-circuit cylinder 6. They are mounted by means of clamps 7, which are located on bars 8, which are mounted on support 9. Handle 10 provides rotation of cylinder 6 around its axis. Short-circuit cylinder 6 has insulation and current-conducting areas. Latter part is designed as hollow cylinder which consists of smooth and tooth-shaped parts, which height is equal to height of recess in secondary unit, teeth of tooth-shaped part are shaped as rectangles. Device may be used in electric drives for rectilinear or reciprocal motion of actuating members. EFFECT: increased functional capabilities. 5 dwg
