Title:
電流源を含む磁気軸方向アバットメントを有するロータリーマシン
Document Type and Number:
Japanese Patent JP4091426
Kind Code:
B2
Abstract:
The rotary machine comprises a rotary shaft ( 2 ) supported by first and second radial magnetic bearings ( 5, 6 ) that are electrically controlled by a control device ( 13 ), said rotary shaft being fitted with an axial abutment device ( 100 ) comprising a rotor formed by a disk ( 101 ) secured to the rotary shaft ( 2 ) and interposed between first and second stators ( 102, 104 ) formed annularly around the rotary shaft and each including at least one annular coil ( 103; 105 ) controlled electrically by a system for servo-controlling the axial position of the rotary shaft. The stator ( 104 ) of the axial abutment device ( 100 ) further comprises a secondary induction circuit ( 106 ), and the disk ( 101 ) secured to the rotary shaft comprises a primary induction circuit ( 107 ) so that during rotation of the shaft, electricity is excited in the secondary induction circuit in order to supply energy to the radial magnetic bearings.
