The invention relates to a method for manufacturing a rotor core or a stator core (205) of an electric motor. The method comprises preparing (110) a continuous strip pattern (202) from an electrical sheet (200). The continuous strip pattern (202) comprises structural features (204, 206) of the rotor core or the stator core (205). The method further comprises applying (120) an adhesive (208) along at least part of a first side of the continuous strip pattern (202) and reeling up (130) the continuous strip pattern (202) to a spiral to form the stator core or the rotor core (205). The invention relates also to an electric motor comprising a rotor core and/or a stator core (205) obtainable by the method, an elevator hoisting machine comprising the electric motor, and an elevator comprising the elevator hoisting machine. 本发明涉及用于制造电机的转子芯或定子芯(205)的方法。该方法包括从电气片(200)制备(110)连续条状图案(202)。该连续条状图案(202)包括转子芯或定子芯(205)的结构特征(204、206)。该方法还包括沿着连续条状图案(202)的第一侧的至少一部分施加(120)粘合剂(208)和将连续条状图案(202)卷起(130)成螺旋状以形成定子芯或转子芯(205)。本发明还涉及包括可由
