Expandable slot closure for an electric machine

The invention relates to a slot-closing device (7) for closing a slot (2) in a stator (S) or rotor (R) of an electric machine (E), said device (7) comprising a closure element (4) that contains a ferromagnetic material and includes a predetermined bending section (9) which extends along a longitudinal direction of the closure element (4) and via which two leg portions (10) that form an obtuse angle (11) of less than 180DEG therebetween are joined to one another. The aim of the invention is to be able to close the slot (2) in a low number of steps. For this purpose, an adhesive layer (5) is disposed on the edges (14) of the leg portions (10), and the adhesive layer (5) is designed to harden under the effect of heat. 本发明涉及种用于封闭电机(E)的定子(S)或转子(R)的凹槽(2)的封槽装置(7)，其具有封闭元件(4)，该封闭元件具有铁磁性材料并且沿着封闭元件(4)的纵延伸方向具有额定弯折区域(9)，经由这个额定弯折区域将两个相互之间以小于180°的钝角(11)布置的支腿区域(10)连接。所述凹槽(2)应能够利用少量的工作步骤封闭。为此在所述支腿区域(10)的相应的边沿(14)上分别布置有粘合层(5)，并且所述粘合层(5)设置用于通过加热来硬化。
