Abstract

PURPOSE:To reduce an eddy current loss through equalization of a magnetic flux distribution by providing direct current electromagnets for guidance of an identical pole around a rotary shaft at regular interval and connecting the edges of iron cores of the direct currnt electromagnets of every pair of identical poles with each other. CONSTITUTION:The top and the bottom of a direct current electromagnet 5 for lifting are provided with direct current electromagnets 7 and 9 for guidance, and these direct current electromagnets 7 and 9 consist of direct current electromagnets 7a-7d and 9a-9d consting of 4 pieces each around secondary iron cores 14 and 15 provided around a rotary shaft 16 and ring plates 8a, 8b, 10a and 10b made of a magnetic substance. Then, the surroundings of the secondary iron core 14 of the upper side of the electromagnet 7 for guidance is provided with the direct current electromagnets 7a-7d for guidance of an identical pole at regular intervals, and a N pole side and a S pole of the edges of an iron core of the each direct current magnet is shortcircuited with the ring plates 8a and 8b made of the magnetic substance at the circumference of the rotary shaft 16. And the lower side of the electromagnet 9 is the same as above also.
