线性电动机及其操作方法
摘要：
本发明提供线性电动机及其操作方法。本发明涉及线性电动机，所述线性电动机具有定子和相对于所述定子可轴向运动的转子，其中，所述转子由沿其纵向轴线具有第一周期长度的周期性的转子磁场永久激励，其中，所述线性电动机包括位置检测装置，所述位置检测装置被设计成检测所述转子相对于所述定子的位置，其中，所述位置检测装置至少包括第一磁场传感器和第二磁场传感器，其中，所述第一磁场传感器和所述第二磁场传感器沿着所述转子的纵向轴线以第一距离彼此间隔开地布置在所述定子上，其中，所述第一距离至少约为所述第一周期长度的六分之一的奇数倍。
摘要（英）：

The invention provides a linear motor and an operating method thereof. The related linear motor includes a stator and a rotor that is axially moveable relative to the stator, wherein the rotor is permanently excited by a rotor magnetic field which is periodic with a first period length (PP) along its longitudinal axis, wherein the linear motor comprises a position detection device, which is designed to detect a position of the rotor in relation to the stator, wherein the position detection device comprises at least a first magnetic field sensor (S1) and a second magnetic field sensor (S2), wherein the first magnetic field sensor (S1) and the second magnetic field sensor (S2) are arranged on the stator spaced apart from each other by a first distance (d1) along the longitudinal axis of therotor, wherein the first distance (d1) is at least approximately an odd multiple of one-sixth of the first period length (PP).
