用于测量转子参数的设备和方法
摘要：
本发明涉及一种用于测量转子参数的设备(1)，其具有：‑与转子或定子无相对转动地连接的增量大小具体化元件(11)，其具有增量标记(12)，‑与所述增量大小具体化元件相对置地布置的增量大小传感器(15)，当所述增量大小具体化元件与所述转子无相对转动地连接时，所述增量大小传感器布置在所述定子上，并且，当所述增量大小具体化元件与所述定子无相对转动地连接时，所述增量大小传感器布置在所述转子上，‑和评估单元(30)，其中，所述设备具有测时器(40)，该测时器在增量标记每次从所述增量大小传感器旁经过时被复位并且重新开启，并且，其中，所述评估单元根据所述测时器的值来确定转子参数用于所述转子的中间转动位置，所述中间转动位置位于所述转子的两个转动位置之间，所述两个转动位置相应于两个相邻的增量标记(12.1，12.2)，所述转子先后从这两个相邻的增量标记旁经过。此外，本发明涉及一种用于测量转子参数的方法以及一种用于减小转子的转动不均衡性的方法。
摘要（英）：

The invention relates to a device for measuring a rotor parameter, including: an incremental material measure, which is connected to a rotor or stator in a rotationally fixed manner and which has increment marks, an increment-measure sensor, which is arranged facing the incremental material measure and which is arranged on the stator if the incremental material measure is connected to the rotor in a rotationally fixed manner and which is arranged on the rotor if the incremental material measure is connected to the stator in a rotationally fixed manner, and an evaluating unit. The device has a timer, which is reset and restarted each time an increment mark passes by the increment-measure sensor. In dependence on a value of the timer, the evaluating unit determines the rotor parameter for an intermediate rotational position of the rotor lying between two rotational positions of the rotor that correspond to two adjacent increment marks that the rotor passes by in succession. The invention further relates to a method for measuring a rotor parameter and to a method for reducing rotational differences of a rotor.
