    • The invention relates to a magnetic circuit structure in an apparatus in which the first machine means is a stator (1) with a winding (3) and the second machine means is a rotor (2). The magnetic circuit is arranged to generate a force effective between the stator (1) and the rotor (2) in the axial direction of the rotor (2), particularly to provide axial magnetic bearing. The separation between the parts of the magnetic circuit effective in the stator (1) on one hand and in the rotor (2) on the other hand is arranged in that part of the magnetic circuit in which the direction of the magnetic flux deviates from the axial direction of the rotor (2), and that the different parts of the magnetic circuit are partly adjacent to each other in the axial direction of the rotor (2), to direct the magnetic flux effective in the magnetic circuit at least partly in the axial direction of the rotor (2).

    • An electromagnetic radial bearing (30) has diametrically opposite pole arrangements in pairs (15'1, 15'3 and 15'2, 15'4) which have limbs (191A, 191B, 191C, 192A etc.) spaced apart circumferentially of a rotor (11), each limb carrying both bias coils (311A, 311B, 311C) and control coils (331A, 331B, 331C). All of the bias coils of all of the limbs are connected in series and driven by low voltage (5 volts) bias current source (34), the bias coils of any pair of pole arrangements facing the rotor are connected with the same current direction relative to the rotor and deliver oppositely directed forces. The control coils of each facing pair of pole arrangements are connected in series with each other and fed from a single high voltage control current source (35) associated with that pair of pole arrangements. The control coils of the pair are wound with opposite current directions relative to the rotor, so that for a particular current direction through the coils, the bias and control coils of one pole arrangement produce aiding fluxes whilst the coils of the opposite pole arrangement produce opposing fluxes. The rotor is suspended between the pole arrangements by the magnetic flux generated by the bias current and displacement of the rotor axis on a radial axis (161) due to external forces sensed by sensor (2216) causes the control current to alter the flux in the opposing pole arrangements to compensate, any tendendy for changes in current to be induced in the bias circuit upon changes in the inductively coupled control coils is cancelled by said opposite winding senses in the pole arrangements of the pair. The above arrangement associated with a single radial displacement axis may also be added to an analogous axial bearing in which annular pole arrangements are disposed each side of a radially extending rotor collar. Axial and radial bearing components may exist within the single bearing arrangement and share a common bias current source.
    • 电磁径向轴承(30)具有直径相对的磁极布置成对(15'1,15'3和15'2,15'4),其具有沿着圆周方向间隔开的四边形(191A,191B,191C,192A等) 转子(11),每个支承带有偏压线圈(311A,311B,311C)和控制线圈(331A,331B,331C)的支路。 所有四肢的所有偏置线圈串联连接并由低压(5伏)偏置电流源(34)驱动,面对转子的任何一对极配置的偏置线圈与相同的电流方向相关 转向转子并提供相反方向的力。 每个面对的极配置对的控制线圈彼此串联连接并从与该对极配置相关联的单个高压控制电流源(35)馈送。 该对的控制线圈相对于转子以相反的电流方向缠绕,使得对于通过线圈的特定电流方向,一个极配置的偏置和控制线圈产生辅助通量,而相反极配置的线圈产生相对的 通量。 转子通过由偏置电流产生的磁通和由于传感器(2216)感测到的外力而在径向轴线(161)上的转子轴线的位移而悬置在极配置之间,导致控制电流改变 用于补偿的相对的磁极布置,在电感耦合的控制线圈的变化中在偏置电路中感应的电流变化的任何趋势被该对的极配置中的所述相反的绕组感测所抵消。 与单个径向位移轴相关联的上述布置也可以被添加到类似的轴向轴承,其中环形磁极布置设置在径向延伸的转子轴环的每一侧。 轴承和径向轴承组件可能存在于单个轴承装置内并共用一个共同的偏置电流源。
