Abstract (en)
[origin: WO2020221866A1] The invention relates to a system comprising a first drive motor (120) and a second drive motor (20). The drive motors (20, 120) are provided for a suction device (400) or a machine tool in the form of a hand-held power tool (200, 300) or a semi-stationary machine tool or form components of the suction device (400) or the machine tool. Each of the drive motors (20, 120) has a stator (80) with an excitation coil assembly (86) and a rotor (40, 140) with a motor shaft (30, 130) which is rotatably mounted about a rotational axis on the stator or relative to the stator (80) using a bearing assembly (24A) and which passes through a shaft through-opening (42, 142) of a laminated core (41, 141) held on a holding portion (33) of the respective motor shaft (30, 130). The holding portions (33) of the motor shafts (30, 130) of the drive motors (20, 120) have identical outer circumferential geometries in the region of the laminated cores (41, 141), wherein the laminated core (141) of the first drive motor (120) is supported directly on the outer circumference of the holding portion (33) of the motor shaft (30, 130) supporting the laminated core (141), and the laminated core (41) of the second drive motor (20) is supported on the holding portion (33) of the motor shaft (30, 130) supporting the laminated core (41) via an electrically insulating insulation element (60A).
