用于电机的解算器
技术领域
本发明涉及一种用于电机的解算器，所述解算器包括解算器定子以及连接模块，其中解算器定子和连接模块一件式构成，并且其中连接模块具有第一插接部段和第二插接部段。
背景技术
在电机、尤其永磁同步电机中，需要相应的转子位置来对所述电机进行调节。作为角度传感器的解算器是一种可能的技术概念，以便测量对于电机的调节所需的转子位置角。
因此，“解算器(Resolver)”应理解为用于角度测量尤其电机的定子与转子之间的角度测量的系统。接下来，可以根据测量到的转子位置角确定电机的变量如马达轴的绝对位置从而确定电机的绝对转子位置、转速和/或旋转方向。
解算器具有可旋转的解算器转子和固定的解算器定子，其中解算器转子和解算器定子经由解算器气隙彼此间隔开。解算器转子尤其可以安装在可旋转构件例如电机的转子上。从现有技术已知各种解算器类型，其中原则上借助于至少一个线圈产生变化的磁场，并且借助于至少一个另外的线圈根据待测量的位置或角位置来探测所述磁场。
除了探测电机的转子的转子角位置之外，电机内的温度、尤其定子的定子绕组的绕组头处的温度是电机的待检测的重要变量。
所有检测的变量通常经由电机的功率电子装置检测。“功率电子装置”尤其应理解为电机的电子部件的可以影响、尤其切换电机的电流的部件。
为了能够设计出在构件和结构空间方面特别高效的电机，并且必要时能够保证在维修情况下进行简单以及成本优化的维修，希望在一个构件上组合尽可能多的电接口。
发明内容
本发明的目的是提供一种用于电机的改进的解算器，所述电机的特征尤其在于在构件以及结构空间方面高效的构造并且以紧凑的方式和方法具有用于检测转子角位置以及也用于检测至少一个定子绕组头温度的所有电接口。
所述需求可以通过本发明的根据独立权利要求1的主题来满足。本发明的有利的实施方式在从属权利要求中描述。
根据本发明的用于电机的解算器包括解算器定子和连接模块。
对应于本发明，解算器定子与连接模块一件式构成。
根据本发明，连接模块具有第一插接部段和第二插接部段。
根据本发明，第一插接部段具有至少一个第一接触销和至少一个第二接触销。根据本发明，第二插接部段具有至少一个第三接触销。对应于本发明，第一接触销与解算器定子电连接，并且第二接触销与第三接触销电连接。
在一个特别优选的实施变型方案中，第一插接部段可与第一配用插接器连接，并且第二插接部段可与第二配用插接器连接，其中第一配用插接器经由线缆束与用于与电机的功率电子装置连接的插接器电连接，并且其中第二配用插接器与电机的至少一个温度传感器电连接。
优选地，解算器定子和连接模块经由塑料灌封件一件式构成。
借助于根据本发明的解算器的构成方案、尤其通过连接模块的构成方案，展示用于记录解算器的信号以及也用于记录电机方面的温度值的电收集点。通过这种方式，朝向功率电子装置引导的信号线路的所有这些信息可以在线缆束中进行组合，并且可以创建在构件和结构空间方面特别高效的解算器。此外，通过这种在构件上的捆绑可以保证在服务情况下进行成本优化的维修。
