    • The invention relates to a magnetic bearing control device and the use of a three-phase converter for controlling a magnetic bearing. According to the invention, a three-phase converter (70) is used for controlling a magnetic bearing (10, 66, 68), all three phase currents (40, 42, 44) of the converter (70) being used for controlling the magnetic bearing (10, 66, 68). A first solenoid of a couple of solenoids (10) of the magnetic bearing (10, 66, 68) is connected to a first (U) and a third (W) phase current output of the converter (70) while a second solenoid of the couple of solenoids (10) is connected to the first (U) and a second (V) phase current output of the converter such that the couple of solenoids (10) can be differently controlled by means of said one converter (70). The converter (70) can also be connected to magnetic bearings that already have a bias winding, which is advantageous for retrofitting such existing magnetic bearings, for example.
    • 本发明涉及磁轴承控制装置和三相转换器用于控制磁轴承的用途。 根据本发明,三相转换器(70)用于控制磁轴承(10,66,68),转换器(70)的所有三相电流(40,42,44)用于控制 磁性轴承(10,66,68)。 磁性轴承(10,66,68)的一对螺线管(10)的第一螺线管连接到转换器(70)的第一(U)和第三(W)相电流输出端,而第二螺线管 螺线管(10)的一对连接到转换器的第一(U)和第二(V)相电流输出,使得可以通过所述一个转换器(70)不同地控制螺线管(10)的对。 转换器(70)也可以连接到已经具有偏置绕组的磁性轴承,这对于改进现有的磁性轴承是有利的。

    • The invention relates to a method for determining the angular position (theta) of a rotor (2) pertaining to an electric motor (1) and comprising a number of pairs of poles. Said method consists of the following steps: a pulse pattern (PM1,PM2,PM3) with a pulse duration (T) flows through at least one stator coil (7) of the electric motor (1), such that the rotor (2) does not rotate by more than 90 DEG, divided between the number of pairs of poles, during the pulse duration (T); the angular acceleration (alpha) of the rotor (2), caused by the pulse pattern flowing through the at least one stator coil, (7) is detected; and the angular position (theta) of the rotor (2) is determined by means of the correlation between the flow through the stator coil (7) and the angular acceleration (alpha) of the rotor (2).
    • 本发明涉及一种用于确定属于电动机(1)并包括多对极的转子(2)的角位置(θ)的方法。 所述方法包括以下步骤:具有脉冲持续时间(T)的脉冲模式(PM1,PM2,PM3)流过电动机(1)的至少一个定子线圈(7),使得转子(2) 在脉冲持续时间(T)期间不旋转​​超过90°,在极对数之间分配; 检测由流经至少一个定子线圈(7)的脉冲图案引起的转子(2)的角加速度(α); 并且借助于通过定子线圈(7)的流量与转子(2)的角加速度(α)之间的相关性确定转子(2)的角位置(θ)。
