    摘要： The invention relates to an electric motor (1) having an armature shaft (10) which is mounted in at least one floating bearing (12), wherein the floating bearing (12) comprises a bearing inner ring (12.1), which is arranged on the armature shaft (10), and a bearing outer ring (12.2), which is accommodated in a bearing seat (14), and a fluid pump for a vehicle fluid system having such an electric motor (1). According to the invention, lubricant is provided between the drive shaft (10) and the bearing inner ring (12.1), which lubricant forms a hydrodynamic lubricant film (16) and generates a constant relative movement between the drive shaft (10) and the bearing inner ring (12.1).

    摘要： The invention relates to a method (71) for diagnosing a heatable exhaust gas probe (11) of an internal combustion engine, wherein a predetermined temporally varying or constant voltage (U
    1 , U
    2 ) or a predetermined temporally varying or constant current (I
    1 , I
    2 ) is generated by means of a voltage source (41, 51), the voltage (U
    1 , U
    2 ) or the current (I
    1 , I
    2 ) is applied to terminals (APE, RT, I PN, RE, ALE, I PE, 37) of the exhaust gas probe (11), a current (I
    1 , I
    2 ) that flows through the voltage source or a voltage (U
    1 , U
    2 ) that is applied to the voltage source when a voltage (U
    1 , U
    2 ) or a current (I1, I2) is applied is detected, and the current (I
    1 , I
    2 ) or the voltage (U
    1 , U
    2 ) is evaluated for diagnosing the exhaust gas probe (11). In order to provide a method (71) for diagnosing the exhaust gas probe (71), which allows a reliable and accurate diagnosis of the exhaust gas probe (71) and permits information to be derived about the type of error potentially present in the exhaust gas probe (71), according to the invention the method (71) is carried out independently of an open and/or closed loop control unit of the internal combustion engine, wherein an operating temperature of the exhaust gas probe (71) is adjusted to a predetermined temperature value by way of a control element (59) that is separate from the open and/or closed loop control unit.
