Abstract

PURPOSE:To decrease the centrifugal force due to eccentricity by mounting a stationary transformer and a rotary transformer opposed thereto to the inside of the rotary shaft so as to reduce the mass of the rotary transformer. CONSTITUTION:A groove (b) is provided either an outer circumferential face 3b of a rotary drum 1 or a bearing inner circumferential face 4c of a stationary drum 4 to form a gas dynamic pressure bearing. Then the rotary shaft 3 with a large diameter is used and the rotary transformer 17 and the stationary transformer 18 opposed thereto are arranged in the inside. Thus, the rotary transformer 17 with a small mass is contained with high accuracy. Thus, the centrifugal force due to eccentricity is reduced.
