    Abstract: The invention relates to an arrangement for indicating a fault in an electrical machine having a stator and a rotor with an air gap between it and the stator. In order to detect impurities or similar objects entering the air gap, a means of supervision is arranged on the stator surface facing the rotor. The means of supervision is at least partially protruding from the stator surface, and the integrity of the included detection element, such as a copper wire, is established using a supervision circuit connected to the detection element.

    Abstract translation: 本发明涉及一种用于指示具有定子和转子的电机中的故障的装置，其中定子和定子之间具有气隙。 为了检测进入气隙的杂质或类似物体，在面向转子的定子表面上布置监督装置。 监控装置至少部分地从定子表面突出，并且所包括的检测元件（例如铜线）的完整性使用连接到检测元件的监督电路来建立。

    Abstract: The object of the invention is a method for manufacturing a winding coil for an electrical machine, as well as the corresponding winding. The electrical machine comprises a stator sheet pack in which slots are arranged at the edge of the inner circumference of the sheet pack for fitting the winding coils. In the method, a winding coil is made of flat wire so that one coil turn (42, 44) goes around a tooth (2) between adjacent slots. According to the invention, the coil turns (42, 44) are manufactured so that one coil end (46) is bent substantially close to the edge (50) of the sheet pack, and a second coil end (60) is bent at a distance from the edge (50) of the sheet pack. The first and second coil end bent at different positions are fitted to the slot one on top of the other around the tooth (2).
