Abstract: A drive motor (10) for a vacuum cleaner or a machine tool, wherein the drive motor (10) includes a stator (20) with a stator coil arrangement (26), and a rotor (30) wherein a sensor arrangement (60) is arranged in a stationary manner with respect to the stator in order to detect a respective angle of rotation position of the rotor (30) with respect to the stator, said sensor arrangement comprising at least two sensors (67A, 67b, 67C). It is provided that the at least two sensors are configured to detect two waves of a magnetic rotating field (FB) of the rotor (30) wherein the sensors generate the switching signals in a manner dependent on a wave of the magnetic rotating field (FB) exceeding or undershooting a switching threshold (SH, SL) of the sensor (67A, 67b, 67C).

Abstract: A drive motor 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. The drive motor (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 (D) on the stator or relative to the stator (80) by means of a bearing assembly (24A) and which passes through a shaft through-opening (42, 142) of a laminated core (41, 141) held on the motor shaft (30, 130). The rotor (40, 140) has a magnet assembly (50) with at least one permanent magnet such that the rotor (40, 140) can be rotated about the rotational axis (D) by energizing the excitation coil assembly (86).

Abstract: A portable power station that includes a box-shaped housing, an energy storage device which is arranged in the housing and is configured to provide an AC voltage, an AC voltage port arrangement at which the AC voltage for an external consumer, in particular a power tool and/or a vacuum cleaner, can be tapped, and a coupling interface for coupling the portable power station to at least one coupling object designed as a system box or vacuum cleaner, in order to form a vertically tension-proof stack together with the at least one coupling object.

Abstract: A system including 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).
