A drive motor () for a vacuum cleaner or a machine tool, wherein the drive motor () includes a stator () with a stator coil arrangement (), and a rotor () wherein a sensor arrangement () is arranged in a stationary manner with respect to the stator in order to detect a respective angle of rotation position of the rotor () with respect to the stator, said sensor arrangement comprising at least two sensors (A,C). It is provided that the at least two sensors are configured to detect two waves of a magnetic rotating field (FB) of the rotor () 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 (A,C).
